Steel products refer to solid straight steel products with a certain section shape and size, including wire, profile and plate, which are formed by plastic processing except pipes. It can be divided into hot rolling, cold bending, cold rolling, cold drawing, extrusion, forging, hot bending, welding and special rolling according to the production method. It can be divided into railway, shipbuilding, mining, structure and construction according to its use. According to the material can be divided into carbon steel, alloy steel and stainless steel. At the same time, these steel products can be reprocessed to form semi-finished products or finished products to meet special requirements. We can according to the customer's different needs, according to the drawings or samples for reprocessing production.
Pipe fittings are the general names of parts and components that play the role of connection, control, direction change, diversion, sealing and support in the pipeline system. Steel fittings are pressure fittings. According to the different processing technology, it is divided into four categories, namely, butt welding pipe fittings (divided into weld and no weld), socket welding and threaded pipe fittings, flange pipe fittings.
According to the application:
1. pipe fittings for connecting pipes are: flanges, live joints, pipe hoops, clamps, clamps, throat hoops, etc.
2. changing the direction of the pipe: bends, bends.
3. pipe fittings changing pipe diameter: variable diameter (different diameter pipe), different diameter elbow, branch pipe table, reinforcing pipe.
4. pipe fittings with additional piping branches: three links, four links.
5. pipe fittings for pipe sealing: gasket, raw material belt, thread, flange blind plate, pipe plug, blind plate, head, welding plug.
6. pipe fittings for pipe fixing: clasp, hook, ring, bracket, bracket, pipe clamp, etc.
According to the connection :1, welded pipe fittings 2, threaded pipe fittings 3, clamping pipe fittings 4, clamping pipe fittings 5, socket pipe fittings 6, rubber ring connection pipe fittings
According to the material divided into 1, cast steel pipe fittings 2, forged steel pipe fittings 3, alloy pipe fittings 4, stainless steel pipe fittings.

Stainless steel tube is a hollow long strip steel made of stainless-steel material. Because of its excellent corrosion resistance, it is mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instruments and other industrial transportation pipelines and mechanical structural components. In addition, when the bending and torsion strength are the same, the weight is light, so it is also widely used in manufacturing mechanical parts and engineering structures, but also commonly used in the field of furniture decoration.
Stainless steel pipe is divided into seamless pipe and welding pipe according to the production mode, seamless steel pipe can be divided into hot rolling pipe, cold rolling pipe, cold pulling pipe and extrusion pipe, etc., cold pulling and cold rolling is the secondary processing of steel pipe; welding pipe is divided into straight welding pipe and spiral welding pipe.
Stainless steel pipes can be divided into round tubes and different tubes according to the cross-sectional shape. The form tubes have rectangular tubes, rhomboid tubes, ellipse tubes, hexagonal tubes, octagonal tubes and various cross-sectional asymmetric tubes.
It can be divided into Austenitic Stainless Steel Tube Ferritic Stainless Steel Tube Martensitic Stainless Steel Tube and Duplex Stainless Steel Tube by the type of stainless steel.
Fasteners are the general term of the class of mechanical parts used in fastening two or more parts (or components) into a whole. It is widely used in energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic and other industries, at the same time, in various kinds of machinery, equipment, vehicles, ships, railway, bridge, construction, structure, tools, instruments, chemical, instruments and supplies, you can see all kinds of fasteners, is the most widely used mechanical foundation parts. It is characterized by a wide variety of variety specifications, different performance uses, and a very high degree of standardization, series, and generalization. Therefore, a class of fasteners that already have national standards is called standard fasteners, or simply standard ones.
Circular steel pipe is both openings and have hollow concentric sections of steel larger than the surrounding. The specifications of steel pipes are indicated by appearance dimensions and inner diameter and wall thickness, with a wide range of dimensions from very small diameter capillary to large round steel pipe of several meters in diameter. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry, and special uses. It can be divided into seamless, ERW, LSAW, SSAW steel pipe according to the production process.
Hollow Section steel Tube is the general name for the steel pipe other than thecircular steel pipe. Such as square, rectangle, oval,elliptical, cone, trapezoidal, spiral, etc. Different steel pipe can more adapt to the particularity of use conditions, save metal and improve the labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, light textile and boiler manufacturing. The methods of producing different pipes are cold pulling, electric welding, extrusion and hot rolling, etc. Compared with the round tube, the different tubes generally have a larger moment of inertia and cross section modulus, and have a large bending resistance and torsion resistance, which can greatly reduce the structural weight and save steel.
