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.

Round tube billet → heating → piercing → three-roll cross rolling, continuous rolling or extrusion → stripping → sizing (or reducing diameter) → cooling → straightening → hydraulic test (or flaw detection) → marking → warehousing.

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 %.We strive for excellence, service the customers”, hopes to become the best cooperation team and dominator enterprise for personnel, suppliers and customers, realizes value share and continuous promotion for One of Hottest for JIS S45c Carbon Seamless Steel Pipes Large Stock Factory Direct Sales 12cr1MOV 15CrMo 35CrMo 45mn2 Ss400, Our concept is to help presenting the confidence of each buyers with the offering of our most sincere service, and the right product.
