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.”

- Q:What are the different methods of insulating steel pipes?
- There are several methods of insulating steel pipes, including using insulation wraps, foam insulation, fiberglass insulation, and pre-insulated pipe systems. Insulation wraps are typically made of materials like rubber or polyethylene and are wrapped around the pipe to provide thermal insulation. Foam insulation involves applying a layer of foam insulation directly onto the surface of the pipe. Fiberglass insulation is another common method, where fiberglass material is wrapped around the pipe to provide insulation. Pre-insulated pipe systems are complete pipe systems that come with built-in insulation and are ready to be installed. These methods help prevent heat loss or gain in the pipes, maintain temperature control, and prevent condensation.
- Q:Can steel pipes be used for cooling systems?
- Yes, steel pipes can be used for cooling systems. Steel pipes are commonly used in various industrial cooling applications due to their durability, high strength, resistance to corrosion, and ability to withstand high pressure and temperature conditions.

- RC pipe is galvanized steel pipe, usually followed by the diameter, such as RC50, that is, 50mm galvanized steel pipe.
- Q:Can steel pipes be used for telecommunications cables?
- No, steel pipes cannot be used for telecommunications cables. Telecommunications cables are typically made of fiber optic or copper materials. Steel pipes are used for various applications in construction and plumbing, but they are not suitable for transmitting data or electrical signals. Fiber optic cables are designed to carry high-speed data over long distances, while copper cables are used for transmitting both data and electrical signals. These cables have specific insulation and shielding properties that steel pipes do not possess, making them unsuitable for telecommunications purposes.
- Q:What are the different types of steel pipe bends for pipeline routing?
- There are several different types of steel pipe bends commonly used for pipeline routing. These include 90-degree bends, 45-degree bends, and custom bends with specific angles as per the pipeline design requirements. Each type of bend serves a specific purpose in redirecting the flow of fluids or gases through the pipeline while maintaining structural integrity.
- Q:What are steel pipes?
- Steel pipes are hollow cylindrical tubes made from steel, which are mainly used for transporting fluids and gases in various industries such as oil and gas, construction, and plumbing. They are known for their strength, durability, and resistance to corrosion, making them an essential component in infrastructure and industrial applications.
- Q:What are the non-destructive testing methods used for steel pipes?
- Some of the non-destructive testing methods used for steel pipes include ultrasonic testing, magnetic particle testing, liquid penetrant testing, radiographic testing, and eddy current testing.
- Q:When can I use the PVC pipe and when to use the galvanized pipe?
- PVC pipeline use temperature is -5 to 90 degrees or so, according to the current market price of around 6000 yuan per ton, the price is cheap. Its corrosion resistance is good, can resist most of the acid and alkali, and unlike the steel pipe that is easy to rust, so in the construction of the upper and lower water pipes and other fields have gradually replaced the trend of steel pipe.
