Product Description
The Seamless Steel Pipe is made of a whole piece of metal and has no seam on the surface.According to the production method,seamless pipes are divided into hot tube, cold-rolled pipe, cold-drawn pipe, extruded pipe, pipe jacking, etc. According to the cross-sectional shape, seamless steel pipes are divided into circular and special-shaped pipes. Special-shaped pipes have many complex shapes, such as square, oval, triangle, hexagon, melon seeds, star and finned pipes.Seamless steel pipes are mainly used as drilling pipes for petroleum geology, cracking pipes for petrochemical industry, boiler tubes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.
Stainless Steel Plate corrosion resistance, bending processing properties and welded parts toughness, as well as the welded parts of the press processing properties of excellent high-strength Stainless Steel plate and its manufacturing method. Specifically, it contains C: 0.02% or less, N: 0.02% or less, Cr: 11% or more less than 17%, the appropriate content of Si, Mn, P, S, Al, Ni, and meet 12 ≤ Cr Mo 1.5Si ≤ 17, 1 ≤ Ni 30 (C N) 0.5 (Mn Cu) ≤ 4, Cr 0.5 (Ni Cu) 3.3Mo ≥ 16.0, 0.006 ≤ C N ≤ 0.030 stainless Steel Plate heated to 850 ~ 1250 ℃, and then heat treatment with a cooling rate of more than 1 ℃ / s cooling. This can become a high strength stainless steel plate containing more than 12% volume fraction of martensite organization, more than 730 MPa of high strength, corrosion resistance and bending processability, and excellent toughness in the heat-affected zone of welding. Then use contains Mo, B, etc., can significantly improve the welded part of the stamping process performance.

Product Specification
Name | Seamless Steel Tube |
Length | MAX 18000 |
OD | 6.0-114.0mm |
Delivery Condition | Annealed, Normalized, Normalized and Tempered |
Surface treatment | Oil-dip, Varnish, Passivation, Phosphating, Shot Blasting |
Application | For high, middle, low pressure boiler and pressure purpose. Used in heat exchangers and boilers to provide highly energy efficient means of heat transfer. The presence of the internal rifling induces centrifugal forces in the mass flow thereby separating the water from the steam fraction and forcing the water towards the tube wall. |
Standard & Grade | ASTM, ASME, A/SA 192, 209, 210 and 213 specifications and all associated grades. EN 10216, DN 17175, BS 3059, JIS 3461 – 3462 |
Approvals | ISMT is ISO 14001, ISO/TS 16949:2002, and OHSAS 18001 approved. In addition we hold approvals from all major national and international official authorities, customers, and third party certification agencies. |
