OEM Factory for Spiral Welded Pipe A53 SSAW Pipe API 5L Standard Oil and Gas Carbon Steel Pipe Precision Honed Tube Seamless Steel Pipe

Short Description:

Heavy Wall Carbon Steel Seamless Pipe is a type of pipe with higher wall thicknesses than average. These are used in petrochemical industries, chemical industries and nuclear power industries. We are Reputed thick wall carbon steel tube Suppliers in China which withstands heavy pressures and stresses due to the strength of the wall. The applications also include oil and gas, research and development areas, defense industry and pulp and paper mills. The heavy wall seamless pipe is marked with the heavy wall schedule numbers such as EH, XH and XS.

There are various schedules to these pipes as they handle various levels of pressures. There are usually sch 80, 100, 120, 140 and 160 that have heavy walls. The heavy wall thickness seamless pipe can sometimes be double extra strong and is denoted as XXS or XXS. The material can vary as there are different grades of carbon steel that are used to make the different thick wall carbon steel pipe types. The high volume, high flow, high pressure systems like oil and gas transmission lines, water lines, and power plant cooling systems all used different types,

Thick-walled seamless steel pipes are mainly used in water conservancy, petrochemical, chemical, electric power, agricultural irrigation, urban construction and other industries. For liquid transport: water supply and drainage. Gas transportation: natural gas, steam, liquefied petroleum gas. Structural uses: used as bridge piling pipes; docks, roads, buildings and other structures.

The key to the quality of thick-walled steel pipes should be thickness uniformity. Uncontrolled wall thickness of thick-walled steel pipes directly affects the quality and practicability of steel pipes, thick-walled steel pipes, and large-diameter seamless steel pipes. It is generally used for various processing and thick-walled parts processing. ,, the uniform wall thickness of the steel pipe will directly affect the quality of the post-processing parts, the wall of the thick-walled steel pipe is not controlled, and the overall quality of the steel is not strict.

Thick-walled steel pipes refer to steel pipes with a pipe diameter to wall thickness ratio of less than 20. Mainly used for petroleum geological drill pipes, petrochemical cracking pipes, boiler pipes, bearing pipes and high-precision structural pipes for automobiles, tractors and aviation. The quality of thick-walled seamless steel pipes depends on the uniformity of wall thickness.

The mechanical properties of heavy wallthickness steel pipes are an important index to ensure the final use performance (mechanical properties) of heavy wallthickness steel pipes steel pipes, and it depends on the chemical composition and heat treatment system of the steel pipe. Therefore, according to different application requirements, the mechanical properties of heavy wallthickness steel pipesare specifically introduced from the aspects of tensile strength, yield point, and elongation.

1. Tensile strength
In the tensile process, the maximum force (Fb) that the sample bears when it breaks is the stress (σ) obtained from the original cross-sectional area (So) of the sample, which is called the tensile strength (σb), and the unit is N/mm2 (MPa). It represents the maximum ability of a metal material to resist damage under tensile force.

2. Yield point
For a metal material with a yield phenomenon, the stress at which the sample can continue to elong without an increase in the force during the stretching process (remains constant) is called the yield point. If the force drops, the upper and lower yield points should be distinguished. The unit of yield point is N/mm2 (MPa).

3. Elongation after breaking
In the tensile test, the percentage of the length of the gauge length increased after the sample is broken to the original gauge length is called the elongation. Expressed by σ, the unit is %.
