Markings will adhere to prescribed specifications in A999/A999M and shall include the NPS or OD and schedule number or average wall thickness, heat number, and NH (when hydrotesting is not performed) and ET (when eddy-current testing is performed) or UT (when ultrasonic testing is performed). The marking shall also include the manufacturer's private identifying mark, the marking requirement of section 12.3 on Hydrostatic or Nondestructive Electric Test, if applicable, and whether seamless (SML), welded (WLD), or heavily cold-worked (HCW). For Grades TP304H, TP316H, TP321H & TP347H, the marking shall also include the heat number and heat-treatment lot identification.
Flattening TestFor material heat treated in a continuous furnace flattening tests shall be made on a sufficient number of pipes to constitute 5% of the lot, but in no case less than 2 lengths of pipe.
Hydraulic Test or Nondestructive TestEach pipe shall be subjected to the Nondestructive Test or the hydraulic test

STAINLESS STEEL SMLS PIPE 2" SCH40S 6MTR 60.3×2.77x6000mm
 

We are a professional manufacturer and exporter of ASTM A312 TP316L  stainless steel pipe in China.
10X17H13M2T: increased resistance to aggressive environments with high acidity, which is not lost even when the material is thermally exposed (up to 600 degrees Celsius). This steel grade is used most of all in the chemical, food and medical industries. Pipes from this steel are enoughPrecisely easy to weld, thus obtaining a monolithic product with an extremely long service life.

Packaging & Shipping

  1. All of our stainless steel seamless pipe & tubes are packaged as per international standard to prevent any possible damage or loss. By default, we will use thick woven plastic bag to bundle the finished pipes together in batches.
  2. For some special pipes & tubes that are vulnerable to dirt, scratches, stress or rough handling, we will suggest wooden case for protection. Kindly note, wooden case can incur extra cost, not only its own cost, but also the increased freight cost, which is especially true for air transportation.
  3. For enhanced customer experience, we also provide dedicated package as per your special requirements.
Certifications

 

 

 

The inspection of our company and products is open to customers themselves or their designated third-party inspectors, such as SGS, BV, TUV, DNV, etc., who are well-known in the industry.
