Spiral steel pipe itself has no life limit, and the service life is mainly related to the operating environment and production process. Spiral steel pipe operating environment is relatively poor In order to extend the service life, the oute.
ASME ANSI B 36.10 and ASTM A53 B Pipe Pressure
1) CW - continuous weld - a method of producing small diameter pipe (1/2-4") 2)
ERW - electric resistance weld - most common form of manufacture for pipe in sizes from 2 3/8-22" OD
- 1 in (inch) = 25.4 mm
- 1 psi (lb/in 2 ) = 6,894.8 Pa (N/m 2 ) = 6.895x10 -2 bar
- Carbon Steel Pipes & Most frequently used as manufactured in area with ASTM specifications A-106 & A-S3. The chemical compositions of these two materials is identical, both are subjected to physical test, but those for A-106 are more rigorous. A-106 are made in grade A & B. Grade B has higher strength properties but is less ductile and for this reason Grade A is permitted only for cold or close coiling.
