The developing trend of LSAW steel pipe in the future:

After cold expansion for lsaw steel pipe, steel tube and pipe end diameter will increase by about one percent difference in diameter of the diameter, roundness, and the pipe ends are greatly improved, also have greatly improved the straightness of the steel pipe, steel pipea length of about 0.5% reduction in wall thickness decreases by about 0.8%.

ASTM A335 P22 is the part of ASTM A335. ASTM A335 P22 alloy steel pipe shall be suitable for bending, flanging, and similar forming operations, and for fusion welding.

ASTM A335 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy-Steel Pipe for high temperature service.

ASTM A333 Grade 10 Standard covers seamless and welded steel pipe for low temperature service. The ASTM A333 Grade 10 steel involved is similar to AISI 4032 low alloy steel. ASTM A333 Grade 10 pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.

ASTM A333 is the Standard Specification for Seamless and Welded Steel Pipe for Low-Temperature Service.

¿Cuál es la diferencia entre la tubería en espiral y otras tuberías de acero?

La tubería de acero sin costura se divide en estirada en frío y laminada en caliente, pero la superficie no ha sido tratada. Existen varios tipos de tubos de acero sin costura y están relacionados con su material y estándares de implementación.

ASTM A333 Gr.8 Ultra-low temperature steel pipe is applicated for Ultra-low temperature service.

ASMT A333 Grade 1 seamless and welded pipes shall be treated to control their microstructure.

ASTM A333 Grade 3 is the part of standard covers wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. ASTM A333 Grade 3 alloy pipe shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.

ERW significa soldadura por resistencia. La soldadura por resistencia tiene las características de alta eficiencia de producción, bajo costo, ahorro de material y fácil automatización. Por lo tanto, es ampliamente utilizado en la aviación, aeroespacial, energía, electrónica, automóviles, industria ligera y otros sectores industriales. Es uno de los procesos de soldadura importantes.

ASTM A333 Grade 7 Standard covers seamless and welded steel pipe for low temperature service.
