So. Spraying derusting is an ideal way of pipeline anticorrosion. Generally speaking. Shot peening (sand) derusting is mainly used on the inner surface of pipes. Shot blasting (sand) rust removal is mainly used for the outer surface of the pipe. Several problems should be paid attention to when using spray to remove rust.

The rust removal grade of square tube is applied to the construction process of epoxy, b, phenolic and other anticorrosive coatings commonly used in square tube. The surface of square tube is generally required to be near white grade (Sa2.5). Practice proves. With this derusting grade, almost all scale, rust and other dirt can be removed. The depth of anchor grain is 40~100μm. Fully meet the anticorrosion layer and square pipe adhesion requirements. The spraying (jetting) derusting process can achieve near-white class (Sa2.5) technical conditions with low operating cost and stable and reliable quality.

Welded pipe is a common pipe in gas pipeline. Welded pipes with diameters greater than 426mm (or 508mm) are generally referred to as large diameter welded pipes. In accordance with the welding tube. Can be divided into spiral welded pipe and straight seam welded pipe two. Spiral welded pipe is the low carbon carbon structural steel or low alloy structural steel steel strip according to a certain spiral Angle (also known as forming Angle) rolled into the pipe blank. Then the pipe seams are welded together to make. It can produce large diameter steel tubes from narrower strips. Spiral welded pipe is mainly spiral submerged arc welded pipe (SSAW)

Square pipe is divided into straight seam welding square pipe and seamless square pipe two kinds. Specifications and models: square 0*600mm. Wall thickness 0.5mm-25mm Length: 5m-12.5m Torque tube: diameter mm. Wall thickness 0.5mm-25mm Length: 5m-12.5m

Square tube can execute EN10210 or technical agreement 355etc product package: spray paint. With oil. Packaging.
