Abstract
This specification covers seamless ferritic alloy-steel pipe for high-temperature service. The pipe shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Grade P2 and P12 steel pipes shall be made by coarse-grain melting practice. The steel material shall conform to chemical composition, tensile property, and hardness requirements. Each length of pipe shall be subjected to the hydrostatic test. Also, each pipe shall be examined by a non-destructive examination method in accordance to the required practices. The range of pipe sizes that may be examined by each method shall be subjected to the limitations in the scope of the respective practices. The different mechanical test requirements for pipes, namely, transverse or longitudinal tension test, flattening test, and hardness or bend test are presented.
1. Scope
1.1 This specification covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for high-temperature service. Pipe ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Selection will depend upon design, service conditions, mechanical properties, and high-temperature characteristics.
1.2 Several grades of ferritic steels (see Note 1) are covered. Their compositions are given in Table 1.
Note 1—Ferritic steels in this specification are defined as low- and intermediate-alloy steels containing up to and including 10 % chromium.
1.3 Supplementary requirements (S1 to S7) of an optional nature are provided. These supplementary requirements call for additional tests to be made, and when desired, shall be so stated in the order together with the number of such tests required.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.
Note 2—The dimensionless designator NPS (nominal pipe size) has been substituted in this standard for such traditional terms as “nominal diameter,” “size,” and “nominal size.”
TABLE 1 Chemical Requirements
A New designation established in accordance with Practice E527 and SAE J1086, Practice for Numbering Metals and Alloys (UNS).
B Grade P 5c shall have a titanium content of not less than 4 times the carbon content and not more than 0.70 %; or a columbium content of 8 to 10 times the carbon content.
C Alternatively, in lieu of this ratio minimum, the material shall have a minimum hardness of 275 HV in the hardened condition, defined as after austenitizing and cooling to room temperature but prior to tempering. Hardness testing shall be performed at mid-thickness of the product. Hardness test frequency shall be two samples of product per heat treatment lot and the hardness testing results shall be reported on the material test report.

- Q: Can steel pipes be used for stadium construction?
- Yes, steel pipes can be used for stadium construction. Steel pipes are commonly used in stadium construction due to their strength, durability, and ability to withstand heavy loads. They can be utilized for various purposes such as supporting the stadium structure, creating frames for roof structures, and facilitating the installation of plumbing and electrical systems. Additionally, steel pipes can be easily fabricated, allowing for efficient construction and customization according to the specific requirements of the stadium design.
- Q: How do steel pipes handle ground settlement?
- Steel pipes are generally robust and durable, making them well-suited for handling ground settlement. The flexibility and strength of steel allow the pipes to withstand the shifting and settling of the ground without significant damage. Steel pipes have a high resistance to deformation, which means they can maintain their shape and structural integrity even when the ground settles or moves. When the ground settles, steel pipes can accommodate the movement by flexing and bending slightly. This flexibility allows them to adjust to changes in the ground without breaking or cracking. Additionally, steel pipes are often designed with joints that can absorb and distribute stress caused by ground settlement. Furthermore, steel pipes have a smooth interior surface that minimizes friction and resistance to the flow of materials. This feature is particularly important when the ground settles because it reduces the likelihood of clogs or blockages due to debris or sediment settling in the pipes. In summary, steel pipes are well-equipped to handle ground settlement due to their strength, flexibility, and resistance to deformation. They can adapt to the movement of the ground without compromising their structural integrity, making them a reliable choice for various applications, including underground infrastructure and pipeline systems.
- Q: Are steel pipes suitable for wastewater treatment facilities?
- Yes, steel pipes are suitable for wastewater treatment facilities. Steel pipes are commonly used in these facilities due to their high strength, durability, and resistance to corrosion. Wastewater treatment facilities typically handle corrosive and abrasive materials, and steel pipes are able to withstand these harsh conditions. Additionally, steel pipes are available in various sizes and configurations, allowing for easy installation and customization to meet the specific needs of the facility. Furthermore, steel pipes can be easily repaired or replaced if necessary, ensuring the longevity and reliability of the wastewater treatment system. Overall, steel pipes are a suitable choice for wastewater treatment facilities due to their strength, durability, corrosion resistance, and flexibility in installation and maintenance.
- Q: How do steel pipes compare to other types of piping materials?
- Steel pipes are known for their exceptional strength, durability, and resistance to corrosion, making them superior to many other types of piping materials. They can withstand high pressure and temperature, making them suitable for a wide range of applications. Additionally, steel pipes are cost-effective, readily available, and easily recyclable, making them a preferred choice in various industries.
- Q: How can galvanized steel tubes be painted on the surface?
- The market is commonly used in alkyd iron red primer, iron red epoxy primer are not suitable for galvanized parts, otherwise it is easy to fall off. It is important to point out that the saponification of the galvanized sheet with alcohol, acid and paint will result in the failure of the coating and the damage of the original zinc coating.
- Q: The difference between carbon and welded steel tubes
- Seamless steel pipe because there is no weld, so can withstand greater pressure, boiler tubes are generally used seamless steel pipe
- Q: Can steel pipes be used for hydropower generation?
- Yes, steel pipes can be used for hydropower generation. Steel pipes are often used in the construction of hydroelectric power plants to transport water from a higher elevation to lower areas, where the water's kinetic energy is converted into mechanical energy to generate electricity. The durability and strength of steel pipes make them suitable for this purpose, as they can withstand the high pressure and flow rates of water in hydropower systems.
- Q: What are the different grades of steel used for manufacturing pipes?
- The different grades of steel commonly used for manufacturing pipes include carbon steel, alloy steel, and stainless steel.
- Q: How to make the steel pipe spray paint is not easy to fall off?
- You're not usually advised to do it yourself, because you can't do it yourself. General powder coating, spray before the treatment is very strict, to be high temperature baking, and their spraying are dry paint, it does not add hardening agent, that is, the surface dry, but not hard, not wear-resistant. So don't scrape off the paint, or you'll look good after spraying, and it will be ugly in a few days,.If you really like to look good, you can buy some stickers back to paste, without affecting the appearance..
- Q: What are the different methods of cutting steel pipes?
- The different methods of cutting steel pipes include using a hacksaw, pipe cutter, angle grinder with a cutting disc, reciprocating saw, plasma cutter, or oxy-fuel torch.
