Galvanized steel pipes are covered with a layer of zinc and these are used for structural applications, underground pipes, above ground pipes, electricity, oil refineries, scaffolding, engineering structures, scientific experiments and fire protection systems.

spiral steel pipe
It is the low carbon structural steel or low alloy structural steel strip according to a certain spiral Angle (called the forming Angle) rolled into a pipe billet, and then the pipe seam is welded together. It can be made of larger diameter steel pipes with narrower strip steel. The specifications are indicated by the outer diameter, wall thickness, and the welded pipe should ensure that the hydraulic test, weld tensile strength and cold bending performance all meet the requirements.

A device called a pipe reducer is used in plumbing systems to join pipes of various diameters. Its purpose is to decrease pipe size by going from a bigger diameter to a smaller one or the other way around. Reducers are frequently utilized in plumbing systems to accommodate varying pipe diameters and are essential for preserving appropriate pressure and flow.

SSAW steel pipe is a spiral seam pipe made of strip coil, regular temperature extrusion molding, and automatic double wire and double embedded arc welding process. The spiral steel pipe will put the strip steel into the pipe fittings, through multi-roll rolling, strip steel roll up, forming a round seam opening, adjust the squeeze roll volume to reduce, the weld gap control in 1 ~ 3mm, and make the both ends of the weld flush.

Square pipe is a hollow square cross-section of light thin-wall steel pipe, also known as steel cooling curved profile. It is made of Q235 hot rolled or cold rolled strip or coil as the base material by cold bending processing and then high frequency welding made of square section shape and size of the section steel. In addition to the thickening of the wall, the corner size and the flatness of the edge of the hot rolled special thick wall square pipe reach or even exceed the level of the resistance welding cold formed square pipe. Good comprehensive mechanical properties, weldability, cold and hot processing properties and corrosion resistance, with good low temperature toughness.

Square tube is a name for square tube, that is, steel pipe with equal side length. It is made of strip steel by processing and rolling. Square tube: Generally, the strip steel is unpacked, flat, crimped, welded to form a round tube, and then rolled into a square tube from the round tube and cut to the required length.

Seamless steel pipes are perforated from whole round steel, and steel pipes without welds on the surface are called seamless steel pipes.
Seamless pipes are widely used, mainly for the manufacture of water wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes and arched brick pipes.
