Threaded pipe:
, used in boilers, after optimization of heat exchange and flow resistance, a threaded smoke pipe The heat transfer is equivalent to that of an ordinary smoke pipe of the same size. This not only significantly reduces the number of smoke pipes, but also reduces the diameter of the pot shell. Therefore, the steel consumption of the pressure components is significantly reduced, saving steel and reducing costs.
. Application in the air conditioning and refrigeration industry. Compared with ordinary smooth light tubes, the heat transfer surface area exceeds that of light tubes, which greatly improves the flow of refrigerant and enhances the boiling and condensation heat transfer effects in the tube. The refrigerant is propelled in a spiral shape through the internal thread, and its pressure loss is reduced above. Manufacturing requires pipe expansion, welding and other processing techniques that are the same as ordinary pipes. The air conditioner is made smaller and lighter. Compared with the use of light pipes, the weight of the pipes is saved by about one-third. Save electricity during operation and save costs.
. When used in heat exchange equipment, steel pipes or stainless steel pipes are rolled into one piece by machine tools. The scaling on the surface of the spiral pipes is in a spiral shape. The temperature changes during the operation of the equipment cause the pipes to expand and contract, so they can The scale layer will fall off on its own, and the scale layer on the bare tube will be a cylinder without any self-shedding force. It has been widely used in power station condensers and boiler auxiliary engine heat exchange systems, and is an ideal choice to replace light tubes and copper tubes.
Threaded pipes (twisted pipes or patterned pipes) are used in arts and crafts, such as the yellow diamond-shaped handrails in King Long Bus and Shanghai Sunlong Bus are new application examples.

Welded steel pipes are divided into general welded pipes, galvanized welded pipes, oxygen blown welded pipes, wire casings, metric welded pipes, roller pipes, deep well pump pipes, automotive pipes, transformer pipes, and electric welding pipes according to their uses. Thin-walled pipes, electric welded special-shaped pipes, scaffolding pipes and spiral welded pipes.
General welded pipe: General welded pipe is used to transport low-pressure fluid. Made of,,, steel. It can also be made of other mild steels that are easily weldable. Steel pipes are subject to hydraulic pressure, bending, flattening and other experiments, and have certain requirements for surface quality. The delivery length is usually -, and delivery of fixed length (or multiple lengths) is often required. The specifications of welded pipes are expressed in nominal diameter (millimeters or inches). The nominal diameter is different from the actual. According to the specified wall thickness, there are two kinds of welded pipes: ordinary steel pipes and thickened steel pipes.
Galvanized steel pipe: In order to improve the corrosion resistance of steel pipes, general steel pipes (black pipes) are galvanized. Galvanized steel pipes are divided into two types: hot-dip galvanizing and electric steel zinc. Hot-dip galvanizing has a thick zinc layer and electro-galvanizing has low cost.
Oxygen blowing welded pipe: used as oxygen blowing pipe for steelmaking. Generally, small diameter welded steel pipe is used, with eight specifications ranging from 3/inch to inch. Made of,,,, or steel strips. To prevent corrosion, some are aluminized.
Wire casing: It is an ordinary carbon steel electric welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameters range from 3-. The wire sleeve has a thin wall and is mostly used after being coated or galvanized, requiring a cold bending test.
Metric welded pipe: Specification is used in the form of seamless pipe, welded steel pipe expressed by outer diameter * wall thickness in millimeters, welded with tropical and cold zones of ordinary carbon steel, high-quality carbon steel or general low alloy steel, Or it can be made by hot-temperature welding and then cold drawing. Metric welded pipes are divided into general-purpose and thin-walled pipes. They are generally used as structural parts, such as transmission shafts, or to transport fluids. Thin-walled pipes are used to produce furniture, lamps, etc. The strength and bending test of the steel pipe must be ensured.
Roller tube: used for belt conveyor roller electric welded steel pipe, generally made of, B, steel and steel, diameter 3. There are certain requirements for the curvature of the pipe, the end face to be perpendicular to the center line, and the ovality. Generally, water pressure and flattening tests are performed.
Transformer tube: used to manufacture transformer heat pipes and other heat exchangers. It is made of ordinary carbon steel and requires flattening, flaring, bending and hydraulic testing. Steel pipes are delivered in fixed lengths or multiple lengths, and there are certain requirements for the bending of the steel pipes.
Special-shaped pipes: square pipes, rectangular pipes, hat-shaped pipes, hollow rubber steel pipes for doors and windows welded from ordinary carbon structural steel and equal steel strips. They are mainly used as agricultural machinery components, steel windows and doors, etc.
Welded thin-walled tubes: mainly used for making furniture, toys, lamps, etc. In recent years, thin-walled tubes made of stainless steel strips have been widely used in high-end furniture, decorations, fences, etc.
Spiral welded pipe: It is made by rolling low-carbon carbon structural steel or low-alloy structural steel strip into a pipe blank according to a certain spiral angle (called forming angle), and then welding the pipe seams. It can Large diameter steel pipes are produced from narrower strips of steel. Spiral welded pipes are mainly used for oil and natural gas transmission pipelines, and their specifications are expressed by outer diameter * wall thickness. Spiral welded pipes are either single-sided or double-sided. Welded pipes should ensure that the hydraulic pressure test, tensile strength and cold bending performance of the weld meet the regulations.
Introduction to oil casing: Oil casing is an important equipment for oil drilling. Its main equipment also includes drill pipes, core pipes and casings, drill collars and small-diameter steel pipes for drilling.
