OEM/ODM Supplier ASTM A53 A106 API5l Seamless Black Steel Pipe
Production specification:
Outer diameter of steel pipe 20-426
Steel pipe wall thickness of 20-426
Product introduction:
① The two digits at the beginning of the steel number indicate the carbon content of the steel, with the average carbon content of a few thousand, such as 40Cr, 30CrMo alloy steel pipe
② The main alloying elements in steel, except some microalloying elements, are generally expressed by several percent. When the average alloy content is less than 1.5%, only the element symbol is generally marked in the steel number, but not the content. However, in special cases, it is easy to confuse, the number “1″ can be marked after the element symbol, such as the steel number “12CrMoV” and “12Cr1MoV”, the chromium content of the former is 0.4-0.6%, and that of the latter is 0.9-1.2%. Everything else is the same. When the average alloying element content ≥1.5%, ≥2.5%, ≥3.5%…… “, the element symbol should be marked after the content, can be expressed as 2, 3, 4…… Etc. For example, 18Cr2Ni4WA.
③ Alloy elements such as vanadium V, titanium Ti, aluminum AL, boron B and rare earth RE in steel belong to microalloying elements. Although the content is very low, they should still be marked on the steel number. For example, in 20MnVB steel. Vanadium is 0.07-0.12% and boron is 0.001-0.005%.
④ “A” should be added at the end of the steel number of high-grade steel to distinguish it from general high-quality steel.
⑤ Special purpose alloy structural steel, steel number prefix (or suffix) represents the purpose of the steel symbol. For example, the 30CrMnSi steel specially used for riveting screws is expressed as ML30CrMnSi.
Manufacturing technology:
1. Hot rolling (extrusion seamless steel pipe) : round tube blank → heating → perforating → three-high diagonal rolling, continuous rolling or extrusion → stripping → sizing (or reducing) → cooling → straightening → hydrostatic test (or inspection) → marking → storage
2. Cold-drawn (rolled) seamless steel pipe: round tube blank → heating → perforation → heading → annealing → pickling → oiling (copper plating) → multi-pass cold drawing (cold rolling) → blank tube → heat treatment → straightening → hydrostatic test (inspection) → marking → storage

Manufacturer for ASTM Ss 201 304 304L 316 316L 310S 309S 430 904L 2205 Welded Round/Square/Rectangular/Hex/Oval Tube or Carbon/Aluminum/Galvanized/Seamless/Stainless Steel Pipe
Metals used in petroleum, chemical, medical, food and light industry
316 stainless steel pipe is a kind of hollow long round steel, which is widely used in oil, chemical, medical, food, light industry, mechanical instruments and other industrial transmission pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is relatively light, so it is also widely used to manufacture mechanical parts and engineering structures. It is also commonly used to produce various conventional weapons, barrels, shells, etc.
The maximum carbon content of 316 stainless steel pipe is 0.03, which can be used in applications where annealing is not allowed after welding and maximum corrosion resistance is required.
316 and 317 stainless steels (see below for the properties of 317 stainless steels) are molybdenum containing stainless steels.
The overall performance of this steel is better than 310 and 304 stainless steel. At high temperature, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses.
316 stainless steel plate, also known as 00Cr17Ni14Mo2, corrosion resistance:
The corrosion resistance is better than 304 stainless steel, and it has good corrosion resistance in the production process of pulp and paper.
The carbide precipitation resistance of 316 stainless steel is better than that of 304 stainless steel, and the above temperature range can be used.
Varieties: 316 stainless steel tubes, 316 stainless steel bright tubes, 316 stainless steel decorative tubes, 316 stainless steel capillary tubes, 316 stainless steel welded tubes, 304 stainless steel tubes.
The maximum carbon content of 316L stainless steel pipe is 0.03, which can be used in applications where annealing is not allowed after welding and maximum corrosion resistance is required.
5 Corrosion resistance
11 316 stainless steel cannot be hardened by overheating.
12 Welding
13 Typical uses: equipment for pulp and paper making, heat exchanger, dyeing equipment, film processing equipment, pipelines, materials for the exterior of buildings in coastal areas
