Understanding your choice of forged pipes options
Understanding the different types of forged pipes, their materials, and their specific uses will help you make an informed decision when selecting the best option for your project. Always consider factors such as material, size, thickness, surface finish, and adherence to industry standards when choosing the most suitable forged pipe.
What are forged pipes?
The forged pipe is a kind of pipe forging made by the forging method. The processing method of the forging tube uses special forging machinery to apply a certain pressure to the corresponding metal billet. The metal billet produces a certain plastic deformation, which can obtain certain mechanical properties, shapes, and sizes of forgings. This cold forging process technology not only improves the finish, dimensional accuracy, and surface strength of the inner bore of the forged pipe but also extends its service life, making its application in the pipeline system more effective.

Dimensions of Forged Pipes
The forged pipes’ dimensions, specifications, and the factors influencing their design.
Standard Dimensional Specifications
To ensure international standards, such as ASME, ASTM, and ANSI typically specify compatibility and interchangeability, forged pipe dimensions. These standards guide the pipe’s nominal size, outside diameter, wall thickness, and weight.
Nominal Size and Outside Diameter
The nominal size of a forged pipe refers to its approximate internal diameter. This value is expressed in inches or millimeters and is often designated by the acronym “NPS” or “DN” for metric sizes. The pipe’s outside diameter (OD) is measured in inches or millimeters and must adhere to specific tolerances specified by the relevant standard. Common nominal sizes range from 1/2 inch (DN15) to 24 inches (DN600), with larger custom sizes available for specialized applications.
Wall Thickness and Schedule
The wall thickness of a forged pipe is a crucial factor that affects its pressure rating and overall strength. Pipes are classified into schedules, designated by the term “Sch,” followed by a number. The schedule number signifies the wall thickness, with higher numbers indicating thicker walls. Common schedules include Sch 40, Sch 80, Sch 160, and Sch XXS. Each schedule has a corresponding pressure rating based on the pipe material and temperature.
Weight and Length
The weight of a forged pipe is expressed in pounds per foot or kilograms per meter and depends on its outside diameter, wall thickness, and material. Standard lengths of forged pipes are generally 20 feet (6 meters) or 40 feet (12 meters), although custom lengths can be manufactured upon request.
Dimensions of Steel Pipes ASME B36.10 and B36.19
1. Wall thickness in mm.
General: Different grades of stainless steel have different specific densities and hence their weight may be less than or greater than the weights listed in this table.
The Forging Process of Forged Pipes
ASTM A182 F91 forged pipe belongs to the sleeve type forgings and is an important raw material for boiler pipe fittings; the quality of the pipe fittings has a greater impact, so control of its quality is of great significance. 91 series steel is the original 9Cr-1Mo type steel based on the addition of strengthening elements V, Nb, N, and so on to the formation of metamorphic steel. Usually referred to as martensitic heat-resistant steel, but the amount of Cr in the U.S. standard is less than 10% as ferritic series, so the name of the standard is still ferritic type (in fact, the type of organization is available through different treatment processes and different phases, so do not have to be bound to the name). In China GB5310-2008, the similar steel grade is 10Cr9Mo1VNb (seamless steel pipe for high-pressure boiler) compared with another Chinese grade 1Cr9Mo1VNb, less N. The same as the U.S. 91 steel is 1Cr9Mo1VNb (N) heat-resistant steel. Now we will introduce the quality control of forging this material with the finished product φ400xφ280×980 as an example.
1. Design forging drawing
Design forging diagram, forging billet diagram, see Figure 1. 937Kg of ingot weight is selected by calculation, the choice of ingot weight, specifications are very important to consider the taper of the mandrel and the internal and external surface is not smooth polygonal additional material, but also consider the processing allowance and the amount of burn loss.
Figure.1 Forging billet diagram
2. Control of ingot
Northeast Special Steel produces the ingot; the smelting method is electric furnace smelting + extra-furnace refining and vacuum degassing; we require four types of non-metallic inclusions coarse and fine system ≤ 1.5, total ≤ 4.5, better than the provisions of GB5310-95; H, O content control in [H] ≤ 3PPM, [O] ≤ 40PPM; five harmful elements Pb, Sn, As, Sb, Bi content are controlled to 200PPM or less, chemical elements to meet the standard requirements, see Table 1 below.
Table.1 91 Steel chemical composition (wt. / %)
|Ni max||C||Cr||Mo||N||Si||Nb||V||P max||S max|
|Tensile strength:585 mpa min|
|Yield strength:415mpa min|
2.1 The harm of non-metallic inclusions
Sulfides reduce the corrosion resistance of steel and plasticity, toughness, and fatigue resistance.
Oxides and silicates destroy the continuity of the steel matrix and lead to stress concentration, thus reducing steel’s plasticity, toughness, and fatigue resistance.
Nitride makes the steel brittleness rise significantly, easy to form cracks.
2.2 Hydrogen and oxygen content control on the quality of steel ingots as follows
Hydrogen in steel is the main hazard of hydrogen cracking defects.
Oxygen will make the mechanical properties of steel decline, and the formation of oxidation inclusions also has the same reduction in steel plasticity, toughness, and fatigue resistance.
2.3 The danger of the five harmful elements
Their melting point and the melting point of steel than relatively low; when the steel is in a solid, they are still in the liquid. Therefore, they are called low melting point elements.
When their content in steel exceeds a certain limit, they will significantly reduce the high-temperature mechanical properties, increase the high-temperature brittleness of steel, and reduce steel’s strength and toughness, making steel brittle.
They are often co-born in one, causing serious segregation, and rarely exist alone, so the damage to the steel is greater.
3. Forging process control
Gas heating furnace heating to forging temperature, the beginning of the forging temperature is less than 1200 ℃, the actual control is 1180 ℃, the final forging temperature is greater than 800 ℃, and the actual control is 850 ℃. The heating time is more than 12.5h to achieve complete austenitization. Beginning forging temperature, the heating temperature of the billet is generally the starting temperature of forging called the beginning forging temperature. Generally lower than the liquid phase line 150-200 degrees, generally speaking, in the premise of not “overheating,” the heating temperature should be as high as possible. The higher the starting forging temperature, the better the plasticity of the material, and the smaller the deformation resistance; the higher the starting forging temperature, the wider the forging temperature range, the longer the forging time, the forging fire times (forging heating times), the less it can improve productivity and reduce energy consumption. At the final forging temperature, the billet in the forging deformation process, the heat gradually dissipates, the temperature drops, the tendency to work hardening increases, plasticity decreases, continue deformation difficulties, and may crack. Therefore, forging deformation must stop at the appropriate temperature, called the final forging temperature. The final forging temperature generally cannot be lower than the metal’s recrystallization temperature so as not to work hardening caused by deformation difficulties or even fracture the workpiece scrap. But it also cannot be much higher than the recrystallization temperature or stop forging recrystallization grain coarse, so the forging temperature range narrows. Heating and insulation, heating and insulation are to make the billet temperature uniform, uniform organization, and malleability uniform, but at high temperatures, for too long will produce an “overheating” phenomenon. Therefore, the heating insulation time to billet heat through the limit, depending on the heating furnace power, furnace temperature, and the thermal conductivity of metal materials.
Forging in 3150 fast forging machines, forging ratio requirements greater than 6, after pier coarse – pulling long – pier coarse – punching – pulling long – reaming, forging furnace cooling, and then annealing heat treatment. The heating curve is shown in Figure 2.
Figure.2 Heating curve diagram
4. Forging inspection
Forging inspection is vital in the manufacturing industry, ensuring that forged components meet the required quality and performance standards.

5. Heat treatment control
F91 AC1 and AC3 according to the difference in composition, AC1 temperature between 800 ℃ and 830 ℃, AC3 temperature between 890 ℃ and 940 ℃. Ms temperature (martensite transformation end temperature) in 100 ℃ (210 °F) or more; F91 material in a relatively wide range of cooling rate, austenite organization completely transformed into martensite organization, and this speed range is usually normalized to meet, so the heat treatment process of F91 material is generally normalized + tempering. The heat treatment curve is shown in Figure 3.
Figure.3 Heat Treatment Curve
6. Rough machining
After the forging is formed, various forgings specifications are processed according to product requirements, leaving a margin for precision machining.
7. Precision machining
The forged pipe forgings after rough machining and heat treatment are precision machined using CNC machine tools to ensure that the forged pipes’ dimensional accuracy, smoothness, and other aspects fully meet the forging drawings’ requirements.
8. Appearance inspection of forged pipes
The main purpose is to inspect whether the appearance of forged pipes meets the size specifications on the customer’s drawings. And carry out ultrasonic testing (UT), magnetic particle testing (MT), hardness testing, tolerance testing, carburization, and other inspections required by the drawings.
9. Mechanical performance testing
To meet customer needs, the mechanical properties of forgings must be tested, mainly yield, tensile, impact, and metallographic tests. Meet the needs of forged pipe inspection.
10. Surface treatment
After visual inspection, mechanical performance testing, and other quality inspections, it has been proven that the quality of the forged pipe product is qualified. Then, according to the customer’s requirements, carry out finishing work such as spraying, rust prevention, and painting.
11. Marking, Packaging, and Transportation: Delivering Quality Forged Pipes
Once the forged pipes have undergone precision machining, they are marked with identifying information, such as part number, heat number, and material grade. They are then carefully packaged to prevent damage during transportation. Finally, the pipes are shipped to their final destination, ready to be integrated into various applications across numerous industries.
How to Measure Forged Pipes?
I measure forged pipes and provide essential tips and best practices to ensure accuracy and precision.

Measuring tape or caliper: A measuring tape or a digital caliper will provide accurate measurements of the forged pipe’s outer diameter (OD), inner diameter (ID), and wall thickness.
Pipe schedule chart: A pipe schedule chart is a reference guide that lists standard dimensions for different pipe sizes and schedules. This will help you determine the correct nominal pipe size (NPS) and wall thickness for your application.
Straight edge and level: A straight edge and level are essential for checking the straightness and alignment of the forged pipe during the measurement process.
II. Measuring Outer Diameter (OD) and Inner Diameter (ID)
The outer diameter (OD) and inner diameter (ID) are critical measurements for determining the size and fit of a forged pipe. Follow these steps to measure the OD and ID accurately:
Measure the OD: Position the measuring tape or caliper around the outer circumference of the pipe. Ensure the tool is perpendicular to the pipe’s length, and measure several points along the pipe to ensure accuracy.
Measure the ID: If the pipe has a visible opening, you can measure the ID directly by positioning the measuring tape or caliper inside the pipe. Otherwise, you can calculate the ID by subtracting twice the wall thickness from the OD.
III. Determining Wall Thickness and Pipe Schedule
The wall thickness of a forged pipe is essential for determining its pressure rating and overall strength. Here’s how to measure the wall thickness and identify the pipe schedule:
Measure the wall thickness: Using a caliper, measure the distance between the outer and inner surfaces of the pipe at several points along its length. Make sure to take measurements at the thickest and thinnest sections of the pipe.
Identify the pipe schedule: Refer to the pipe schedule chart and find the corresponding schedule number based on the measured OD, ID, and wall thickness. The schedule number indicates the pipe’s pressure rating and overall durability.
IV. Assessing Pipe Straightness and Alignment
Ensuring a forged pipe’s straightness and proper alignment is crucial for its performance and longevity. Here’s how to check these aspects:
Check straightness: Place a straight edge along the length of the pipe. The pipe is considered straight if the straight edge rests evenly on the pipe without any gaps or deviations.
Verify alignment: Place a level on the pipe’s surface to check its horizontal and vertical alignment. If the bubble is centered within the level, the pipe is aligned correctly.
V. Documenting Measurements and Inspection Results
Documenting the measurements and inspection results is essential for quality control and traceability. Ensure you record the following information:
Forged pipe dimensions (OD, ID, wall thickness, and schedule number);
Straightness and alignment results;
Date and time of inspection;
Inspector’s name and signature.
