Spiral Welded steel Pipes
HS Code: 73051900

SSAW steel pipe, also known as spiral submerged arc welded steel pipe, is a spiral welded steel pipe produced by double-sided submerged arc welding. Spiral welded pipes are formed using narrower sheets or hot rolled coils, which greatly reduces their production costs. The spiral welding process allows the production of large diameter pipes suitable for transporting large quantities of oil and gas.

METAL GRADE:
Q235B: Material Q235B, Equivalent of European standard DIN EN S235JR and ASTM A36. Implementation standard: GB / T9711-2020.
Q235 stands as a plain carbon structural steel with a yield strength of approximately 235MPa, a value that may vary with material thickness. The ‘Q’ symbolizes the material’s yield limit, while ‘235’ denotes the approximate yield strength in megapascals (MPa).

Q345B: Material Q345B, Equivalent of European standard EN 10025-2 S355JR or S355J2.
The ASTM equivalent material for Q345B steel is ASTM A572 Grade 50. Both Q345B and ASTM A572 Grade 50 have similar properties and are suitable for structural applications. 

Q345B: Q345B is a low alloy steel with a carbon content of less than 0.2%. It has good properties for welding, machinability, cold stamping, low temperatures, and comprehensive properties. It’s used in a variety of applications, including bridges, ships, vehicles, and construction.

Standard
ASME 36.10, ASME 36.19 are the key specifications covering the standardization of dimensions of welded and seamless wrought steel pipe. ASME B16.25 covers the preparation of butt weld connections between pipes and ASME B16.49 covers the marking details.
ASME 36.10
This standard covers the standardization of dimensions of welded and seamless wrought steel pipe for high or low temperatures and pressures. Pipe NPS 12 (DN 300) and smaller have outside diameters numerically larger than corresponding sizes. In contrast, the outside diameters of tubes are numerically identical to the size number for all sizes.
The size of all pipe is identified by the nominal pipe size. The manufacture of pipe NPS ⅛ (DN 6) to NPS 12 (DN 300), inclusive, is based on a standardized outside diameter (O.D.). This O.D. was originally selected so that pipe with a standard O.D. and having a wall thickness that was typical of the period would have an inside diameter (I.D.) approximately equal to the nominal size. Although there is no such relation between the existing standard thickness – O.D. and nominal size – these nominal sizes and standard O.D.s continue in use as “standard.” The manufacture of pipe NPS 14 (DN 350) and larger proceeds on the basis of an O.D. corresponding to the nominal size.
ASME 36.19
This Standard covers the standardization of dimensions of welded and seamless wrought stainless steel pipe for high or low temperatures and pressures.
Pipes NPS 12 (DN 300) and smaller have outside diameters numerically larger than their corresponding sizes. In contrast, the outside diameters of tubes are numerically identical to the size number for all sizes. The wall thicknesses for NPS 14 through 22, inclusive (DN 350-550, inclusive), of Schedule 10S; NPS 12 (DN 300) of Schedule 40S; and NPS 10 and 12 (DN 250 and 300) of Schedule 80S are not the same as those of ASME B36.10M. The suffix S in the schedule number is used to differentiate B36.19M pipe from B36.10M pipe. ASME B36.10M includes other pipe thicknesses that are also commercially available with stainless steel material.
API 5L
ANSI / API 5L specifies the manufacture of two product levels (PSL1 and PSL2) of seamless and welded steel pipe for the use of a pipeline in the transportation of petroleum and natural gas. For material use in a sour service application, refer to Annex H; for offshore service application, refer to Annex J of API 5L 45th Edition.
Grades covered by this specification are A25, A, B and “X” Grades X42, X46, X52, X56, X60, X65, X70, and X80. The two digit number following the “X” indicates the Minimum Yield Strength (in 000’s psi) of pipe produced to this grade.
