    What is SSAW Steel Pipe?

    SSAW steel pipe（Spiral Submerged arc welding pipe） is made up of hot-rolled coiled steel using a double-sided submerged arc welding method. The welding process allows the steel pipes manufacturers to produce large-diameter steel pipes suitable for different applications.

    The Advantages of SSAW Pipes

    SSAW steel pipe can be produced in longer length (maximum length up to 50 meters) compared to LSAW steel pipes

    Due to its spiral seam SSAW pipe has an accurate diameter accuracy and strength

    The sizes are adjustable & can be tailored to end-users requirement

    Usage: Used for low pressure liquid delivery, such as water, gas, and oil.

    SSAW steel pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire double submerged arc welding process made of spiral seam pipe. Spiral steel pipe will strip into the pipe unit, the multi-roll rolling, strip rolled up, forming a circular gap opening gap, adjust the squeeze roll reduction, the weld gap control in the 1 ~ 3mm, and make both ends of the weld flush.

    We have engaged in the steel pipe industry for 30years with rich exprience and strong strengths.  Welcome to contact us to get more information about spiral welded pipe!
