A312 type TP316L is a low carbon austenitic stainless steel grade. A312 TP316L is made of high quality nickel, chromium and molybdenum composition and can be used in different industries. This gives items of this grade excellent resistance to corrosion and oxidation. This grade covers standard seamless, welded, ERW, EFW and cold drawn pipe assemblies. ASME SA312 Gr 316L Seamless Tubing is a pressure vessel assembly designed for high temperature and high pressure applications. These pipes are produced as hot billets are passed through extruded metal to precisely shape the material to the correct size. This SA312 grade 316L seamless pipe is slightly more expensive due to the material from which they are produced; however, this grade has excellent load carrying capacity and strength as they do not have any welds or seams on the surfaces of these pipes. ASTM A312 Tp316l cold drawn seamless pipe is manufactured shortly after the hot rolling process. Machined at room temperature, these pipes run on molds and have higher strength and surface finish than regular grades of steel.
A312 Type 316L ERW pipe is produced by rolling sheet or strip and forming longitudinal seams. In this process, high-voltage current is passed through the metal to weld it in place without the need for filler material. ASME SA312 Grade 316L Efw pipes are produced with high speed beams that allow kinetic energy to be converted into heat, the workpiece melts and the material is welded into place. Our agency believes in quality above all else and ensures that we deliver the best products to all of our stores. If you have any questions or concerns about our products or their pricing, please contact us or visit any of our stores for more information.
Some of the quality tests carried out by our quality department includes:
| Corrosion Test | Only when specifically requested by the customer |
| Chemical Analysis | Conduct tests according to required quality standards |
| Destructive / Mechanical Testing | Tensile | Hardness | Flattening | Flare | Flange |
| Reverse-bend and Re. flat tests | Fully compliant with relevant standards and ASTM A-450 and A-530 specifications, ensuring trouble-free extension, welding and use on the client side |
| Eddy Current Testing | Done to detect homogeneities in subsurface by using Digital Flaw-mark Testing System |
| Hydrostatic Testing | 100% hydrostatic test, check pipe leaks according to ASTM A 450 specification, the maximum pressure we can support is 20Mpa/7s. |
| Air Under Pressure Test | Check for any signs of air leakage |
| Visual Inspection | After passivation, each tube is subjected to a thorough visual inspection by trained personnel to detect surface defects and other defects |
Supplementary Testing : In addition to the above tests, we also carry out supplementary tests on finished products. Tests carried out in this regard include:
