12m Length DN3000 Ssaw Steel Pipe Astm A252 Standard

ASTM A252 Standard Specification For Welded And Seamless Steel Pipe Piles Ssaw Steel Pipe

This specification covers nominal (average) wall steel pipe piles of cylindrical shape and applies to pipe piles in which the steel cylinder acts as a permanent load-carrying member, or as a shell to form cast-in-place concrete piles. Pipe piles are produced as both welded and seamless products.The processed spiral steel pipe has greater flexibility in the size and specification range of diameter and wall thickness, especially in the production of high-steel grade thick wall pipe, especially in small and medium-sized thick wall pipe has incomparable advantages, which can meet the user's more requirements in the specification of spiral steel pipe.

Adopting the advanced double-sided submerged arc welding technology, the welding can be realized in the optimal position, and it is not easy to have the defects such as wrong side, deviation and incomplete welding, etc., and easy to control the welding quality.General low pressure fluid conveying, spiral seam submerged arc welded steel pipe SY5037-2000, using double-sided automatic submerged arc welding or single-side welding method for water, gas, air and steam and other general low pressure fluid conveying submerged arc welded steel pipe.Now the common standard of spiral steel pipe is generally divided into :SY/T5037-2008(Ministry standard, also known as the spiral seam submerged arc welded steel pipe for ordinary fluid transmission pipeline), GB/T9711.1-2008(national standard, also known as the oil and gas industry delivery technical conditions of steel pipe Part I:A-class steel pipe (GB/T9711.2 B-class steel pipe), API-5L(American Petroleum Association, also known as pipeline steel pipe.ASTM A252 / A252M Standard Specification for Welded and Seamless Steel Pipe Piles.
