The Use of Welded Steel Pipe or Application Range

General Pipe: Average welded steel pipe used to transport low pressure fluid. With Q195A, Q215A, Q235A steel. Easy welding may also be used in other soft steel. Pipe to carry water pressure, bending, flattening and other experiments, there are certain requirements for surface quality, delivery is usually a length of 4-10m, often required length (or double length) delivery. Pipe specifications expressed with nominal diameter (mm or inch) nominal diameter different from the actual, pipe wall thickness according to the provisions of ordinary steel and thicker steel are two forms of steel pipe end divided by threaded and non- threaded two kinds.

Galvanized steel pipe: To improve the corrosion resistance of steel, steel pipe for general (clarinet) galvanized. Galvanized steel pipe hot galvanized and zinc two kinds of electrical steel, hot dip galvanized thick galvanized, electro-galvanized and low cost.

Oxygen pipe: as steelmaking oxygen tube, usually with a small -diameter welded steel pipe, specification consists of 3 /8 inch -2 inch eight kinds. With 08,10,15,20 or Q195-Q235 steel is made. To corrosion, and some for aluminized.

Wire casing: also ordinary carbon steel welded pipes, used in a variety of structural concrete and distribution projects, common nominal diameter from 13-76mm. Wire condom wall is thinner, mostly used for coating or galvanized, cold bend test requirements .

Metric pipe: seamless form of specifications, with the diameter * thickness in millimeters of welded steel, with ordinary carbon steel, high carbon steel or low alloy steel Prudent Energy tropical, cold strip welding, soldering or tropical then by cold call method is made. To ensure the strength and bending test tube, metric walled pipe of universal energy and ordinary as structural components, such as shafts, or transmission fluid, for the production of thin-walled furniture, lamps, etc.

Roller tube: welded steel pipe or API steel pipe for belt conveyor idlers, usually with Q215, Q235A, B steel and 20 steel, diameter 63.5-219.0mm. On the tube bending, end with the vertical centerline, there are certain requirements joviality, ordinary pressure and flattening test.

Transformer tube: for the manufacture of transformers and other heat pipe heat exchanger, using ordinary carbon steel, require flattening, flaring, bending, hydraulic tests. Pipe to length or double length delivery, bending the steel pipe has certain requirements.

Pipes: from general carbon structural steel pipe and welded steel 16Mn, square tube, rectangular tube, cap -shaped tube, empty plastic steel doors and windows with steel, mainly for agricultural machinery components, steel window doors.

Welded thin-walled tube: mainly used to make furniture, toys, lamps, etc. In recent years, the production of thin-walled stainless steel tube with a very wide application, fine furniture, decoration, fences and so on.

Spiral welded pipe : It is the low-carbon carbon structural steel or low alloy steel strip at a certain angle of the helix ( called molding angle ) rolled into a tube, then welded together to form the tube, it can be used narrower strip production of large diameter steel pipe. Spiral welded pipe is mainly used for oil and gas pipelines, and its diameter * thickness expressed. Spiral welded single-sided and double-sided welding, pipe should ensure that hydrostatic test, weld tensile strength and cold performance to meet the requirements.
