PRODUCT CENTER
201 stainless steel is mainly used for decorative tubes, industrial tubes and some shallow stretched products. Such as: oil waste gas combustion pipeline; Engine exhaust pipe; Boiler shell, heat exchanger and heating furnace components; Silencing parts for diesel engine; Boiler pressure vessel; Chemical transport vehicle; Expansion joint; Spiral welded pipe for gas furnace pipe and dryer, etc.
Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the passive layer. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.
Ductile iron pipe is a kind of cast iron, is an alloy of iron, carbon and silicon. Graphite in ductile iron is in the form of spheres, the general size of the graphite is 6-7 levels, the quality of the casting pipe is required to control the level of spheroidization for the 1-3 level (spheroidization rate ≥ 80%), and thus the mechanical properties of the material itself has been better improved, with the essence of iron, steel performance. Ductile iron pipe after annealing, its metallurgical organization is ferrite plus a small amount of pearlite, mechanical properties are better.

There are various types of grouting pipe, including common grouting pipe, grouting steel flower pipe, casing valve pipe, advanced small conduit, disposable plastic grouting pipe, pipe shed pipe, etc., which can be used for different occasions and needs according to different specifications and materials. Grouting pipes can also be used in pre-buried grouting pipe systems for permanently sealing concrete construction joints, cold joints, pipe leakage joints, wall gaps, etc.

Seamless square tube, is the four sides and four corners of the steel pipe, from the seamless steel pipe cold-drawn extrusion molding of square steel pipe, seamless square tube and welded square tube has the essential difference. The steel pipe has a hollow cross-section and is used in large quantities as a pipeline for the transportation of fluids. Seamless square tube is a kind of quadrangular steel tube, extruded from seamless steel tube by cold drawing or hot rolling and other processes. Unlike welded square tubes, seamless square tubes have no seams around the hollow section, so they have better sealing and strength.
