Yuhong Special Steel has been engaged in seamless welded steel pipes of austenitic stainless steel and nickel alloy steel (Hastelloy, Monel, Inconel, Inconel) for more than 30 years, and sells steel pipes every year. Over 80,000 tons. Our customers cover more than 45 countries including Italy, UK, Germany, USA, Canada, Chile, Colombia, Saudi Arabia, South Korea, Poland, Singapore, Australia, France, etc.
A312 Tp304 tube is pushed or pulled to form a shape usually formed from a round billet of raw material. It is more corrosion resistant than ordinary 304 stainless steel pipe. Our 304 stainless steel seamless tube has a low carbon content, making it highly weldable and formable.
Stainless steel 304 welded pipe can be in different shapes such as SS 304 round pipe or SS 304 square pipe. SS 304 Erw tube is used for long service chemical and industrial applications. There are different schedules such as the SS 304 Sch 40 pipeline. Our products are of high quality and have very competitive prices in the market.
YUHONG supplies SS 304 Seamless Pipe from 6" NB to 120" Nb, including all types of seamless, ERW, welded, fabricated and grooved. All our materials meet the international specifications of ASTM A312, A249 and ASME SA 312 .We can supply 304 steel pipe thickness from 1.2mm to 2mm.Standard size of pipe length is 3m, 6m and 10m. But we are one of the suppliers who provide 304 grade fixed length pipe, which can save your cost and avoid Waste. We offer pipes in all surface finishes such as polished, annealed, anodized, sandblasted, brushed, polished, bright annealed, cold drawn, etc. We can also provide SS pipe polishing services in 182 - 320 grit.
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
