What types of SSAW pipe piles can be divided into?

According to the shape of the welded seam can be divided into straight seam welded pipe and SSAW pipe pile. Spiral submerged arc welded steel pipe SY5036-2000 for the transmission of pressurized fluids, mainly used for the transmission of oil and gas pipelines;

Spiral high-frequency welded steel pipe SY5038-2000, welded with high-frequency lap welding method, spiral high-frequency welded steel pipe for the transmission of pressurized fluids.SSAW pipe pile has strong pressure-bearing capacity, good plasticity, easy to weld and process forming.

General low-pressure fluid transmission, spiral submerged arc welding steel pipe SY5037-2000, using double-sided automatic submerged arc welding or single-sided welding method with SSAW pipe pile.

Generally speaking, different SSAW pipe pile have different testing standards. The testing process of SSAW pipe pile is based on the needs of spiral steel pipe customers.

Analysis of Classification Standard of SSAW Pipe Piles

SSAW pipe pile for liquid transportation: water supply, drainage, sewage treatment works, mud transfer, marine water transfer; for gas transportation: gas, steam, liquefied petroleum gas; for structural use: for piling pipe, for bridges; docks, roads, building structure with pipe, marine piling pipe, etc.Commonly used spiral welded pipe materials: Q235A, Q235B, Q345, L245, L290, etc.

Now the common standard of SSAW pipe pile is generally divided into: SY/T5037-2008 (Ministry standard, also known as ordinary fluid transmission pipeline with spiral submerged arc welded steel pipe), GB/T9711.1-2008 (also known as the first part of the technical conditions for the delivery of steel pipe for oil and gas industry.

 

What are the applications of different types of SSAW pipe piles?

SSAW pipe pile is mainly used for oil and natural gas transmission pipeline, and its specification is expressed by outer diameter wall thickness. SSAW pipe pile has single-sided welded and double-sided welded. The welded pipe should ensure that the hydraulic test, tensile strength of the welded seam and cold bending performance should meet the regulations.Spiral high-frequency welded steel pipe for general low-pressure fluid transmission (SY5039-2000) is a spiral high-frequency welded steel pipe for general low-pressure fluid transmission made of hot-rolled steel coil as billet, spiral formed at regular temperature and welded by high-frequency lap welding method.Used for civil construction structures, piers, bridges and other foundation pile steel pipe.

(1) Used for liquid transportation: water supply and drainage.

(2) Gas transportation: natural gas, steam, liquefied petroleum gas.

(3) Structural use: pile driving pipe, bridge.

(4) Wharf, road and building structure used for SSAW pipe piles.
