Spiral Welded Steel Pipe Ssaw Steel Pipe
SSAW spiral welded pipe includes ordinary spiral steel pipe and thick wall spiral steel pipe. The advantages of thick wall spiral steel pipe compared with ordinary thick wall spiral steel pipe are: high compressive strength, high impact strength, high safety performance and longer service life. SSAW spiral welded pipe generally has higher strength than straight seam welded pipe. It can produce welded pipe with larger diameter with narrow blank, and can also produce welded pipe with different diameter with blank of the same width.

Longitudinally Submerged Arc Welding (LSAW) Welded Steel Pipe
LSAW pipe is Longitudinal Submerged Arc Welding pipe.
The production technology of LSAW pipe is flexible, and it can produce specifications and models that can not be produced by high frequency steel pipe, spiral steel pipe and even seamless steel pipe.

Large Diameter Heavy Wall Welded Steel Pipe
The submerged arc welding technology used in large-diameter thick wall welded pipe has the characteristics of high weld quality, high production efficiency, no arc light and little smoke. It is mainly used in pressure vessel, pipe fitting manufacturing, beam and column, low-pressure fluid and steel structure engineering. Large diameter thick wall welded pipe includes large diameter straight seam thick wall welded pipe and large diameter spiral thick wall steel pipe. The main executive standards of large diameter straight seam thick wall steel pipe are gb/t3091-2008, gb/t9711.1-1997 and API 5L standards.

GALVANIZED Welded Steel Pipe
Galvanizing is process of coating zinc over steel. Galvanized steel pipes are widely used in agriculture and construction industrial because the galvanizing can form dense oxide protective coatings to protect steel structures inside steel pipes. Can galvanized steel pipe be welded? Yes! In fact, there is no difference between their welding and ordinary carbon steel pipe, but due to the existence of galvanized layer, they are prone to crack, porosity and slag inclusion in welding, and the welding quality cannot be guaranteed.

Q235 Q195 Carbon Steel Welded Oxygen Lance Pipe
Oxygen Lance Pipe is used as oxygen blowing pipe for steel making, generally small-diameter welded steel pipe, with eight specifications ranging from 3/8 inch to 2 inch. Made with 08, 10, 15, 20 or Q195-Q235 steel strip. In order to prevent corrosion, some are aluminized.
