The process of Ssaw steel pipe:
Steel coils→Ray material test → Delivery straightening → Plate cutting and welding → circle shear edge milling → Forming → inside auto-welding → Outside auto-welding → Online ultrasonic inspection → Fixed length cutting → Visual inspection for outside seam → Visusl inspection for inside seam → X-ray inspection for welding seam → Even end and end bevel → Hydrostatic test → Ultrasonic inspection → Final product inspection → Marking → Store up
A53 PIPE SPECIFICATIONS
A/SA53
NPS 1/8″ – 26″
Schedules 10 through 160, STD, XH and XXH
ASTM A53 pipe (also referred to as ASME SA53 pipe) is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. It is suitable for welding and for forming operations involving coiling, bending, and flanging, subject to certain qualifications.
American Piping Products stocks a full range of A53 pipe (SA53 Pipe) in:
Grade B
NPS 1/8” to 26” diameter
Schedules 10 through 160, STD, XH and XXH
Scope
ASTM A53 pipe covers Seamless and Welded, Black and Hot-Dipped Galvanized nominal (average) wall pipe for coiling, bending, flanging and other special purposes and is suitable for welding. Continuous-Welded pipe is not intended for flanging. Purpose for which pipe is intended should be stated on order.
Looking for specific post-production services? See our full list.
Materials and Manufacture
The steel for both seamless and welded pipe shall be made by one or more of the following processes: open-hearth, electric furnace, or basic-oxygen. The weld seam of electric-resistance welded pipe in Grade B shall be heat treated after welding.
