ASTM A312 TP316L Austenitic Stainless Steel Seamless Cold Rolled
Pipe
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.
Description
Grade 316L is a low carbon version of 316 stainless steel. When
cold worked, 316 produces high yield and tensile strengths similar
to dual-phase grades.
It is commonly used in the chemical and petrochemical industries,
food processing, pharmaceutical equipment, medical devices,
drinking water, wastewater treatment, marine applications and
construction applications near coasts or urban areas.
These seamless pipes are highly resistant to chloride corrosion, so
316L stainless steel pipes are resistant to pitting and crevice
corrosion even in chloride-rich environments. Our stainless steel
pipe 316L seamless products can be used in marine, marine
applications, sea water purification systems and wastewater
management applications. There are different pipe plans to
accommodate different diameters and wall thicknesses. Stainless
Steel Tube 316L Schedule 40 is a medium pressure vessel
capacity, while Stainless Steel Tube 316L Schedule 10s has a
relatively small wall thickness. Our 316L Seamless Pipe Schedule 40
pipe is one of the most commonly used pipes in the oil and gas
industry. Our resistance welded SS 316L Erw tubes are stronger and
last longer. The advantage of 316L welded pipe is that it is easy
to weld with or without filler material. We also offer square tube
316L for extra strength in structural applications. Please contact

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:
- Eddy Current Testing
- O.P Testing
- Radiography Testing
| - Corrosion Testing
- Micro Testing
- Macro Testing
| - IGC Testing
- Ultrasonic testing
