A312 TP304N Welded pipe Specification: ASTM A312 specification covers seamless pipe and welded pipe for austenitic stainless steel. These high performance austenitic stainless steels have a fully austenitic microstructure in the quench annealed condition.

RYIN Stainless Welded pipe factory produce and export of stainless steel seamless and welded pipes per ASTM A312 in Grade of TP304N/304L, TP316/316L/316Ti, TP321/tp321H, TP SS347H, TP317L, TP904L TP309S/H TP310S/H and SS446 among other special grades. Stainless steel seamless tubes are available in compliance with ASTM A213,ASTM A269 ASTM A312 ASTM A in common grades of such as 304/304L and 316/316L in standard tube sizes and wall thicknesses. We can offer custom size cold drawn stainless-steel pipes and stainless-steel tubes to our customers. Generally stainless-steel pipes and stainless-steel tubes are available in standard OD or NB sizes. However, with our tube processing capabilities we can offer any custom size outside DIA and thickness to our customers.

Stainless TP304N welded pipe production range:
OD12.7 to 2500mm, Thick:0.8mm-60mm, Length 500mm to 13000mm

Our TP304N Stainless Steel Welded pipe manufactured from cold-forming process using coils of steel sheet with automated spiral welds. Great strides were made in quality control, testing, joints and protective coatings. Welded steel pipe is available in wide ranges of sizes and properties of the steel. These ERW Pipes carry high strength, ease of installation, high flow capacity, leak resistance, long service life, reliability and versatility, and economy.

A312 TP304N Welded pipe ship marking:

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 TP304N, TP316H, TP321H & TP347H, the marking shall also include the heat number and heat-treatment lot identification.

Stainless Steel 316/316L pipes and tubes are available in both seamless and welded form in OD and NB sizes. In addition to standard sizes, which are available in stock, our specialty is to Supplier and supply custom size 316/316L cold drawn seamless tubes from our factory.

Selecting filler metal for stainless steel pipe is about enhancing the properties of the weld and meeting the requirements of the application. Filler metals with an “L” designation, such as ER308L, provide a lower maximum carbon content, which can help retain corrosion resistance in low carbon stainless alloys. As an example: if you weld a 304L base metal with a standard 308 filler metal, you’ll actually raise the carbon content of that joint and increase the chance of corrosion. In high purity applications – food, beverage, pharmaceutical – that low carbon content is critical for maintaining corrosion resistance. Conversely, a filler metal with an “H” designation provides higher carbon content for applications requiring greater strength, particularly at high temperatures.
