Stainless steel pipe is a kind of hollow long circular steel, mainly widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transportation pipes and mechanical structural components. In addition, the bending and torsional strength are the same, and the weight is light, so it is also widely used in the manufacture of mechanical parts and engineering structures. Also commonly used as furniture kitchenware.

Carbon steel pipes are divided into hot rolled and cold rolled (drawn) steel pipes.
Hot rolled carbon steel pipe is divided into general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, geological steel pipe and other steel pipes.
Cold rolled (dial) carbon steel pipe in addition to general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, other steel pipe, also includes carbon thin-wall steel pipe, alloy thin-wall steel pipe, stainless thin-wall steel pipe, special-shaped steel pipe. The outer diameter of the hot-rolled seamless pipe is generally greater than 32mm, the wall thickness is 2.5-75mm, the outer diameter of the cold-rolled seamless steel pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, the wall thickness is less than 0.25mm, and the size accuracy is higher than that of the hot-rolled seamless pipe.

Fire coated plastic composite steel pipe, with steel pipe as the base pipe, the outer wall is coated with high adhesion, impact resistance, corrosion resistance and weather resistant thermosetting powder coating.



Fire coated plastic composite steel pipe, with steel pipe as the base tube, the outer wall is coated with high adhesion, impact resistance, anti-corrosion and weather-resistant thermosetting powder coating, and the inner wall is coated with high adhesion, anti-corrosion, food-grade hygienic thermoplastic powder coating. Using sandblasting chemical dual pre-treatment, preheating, inner coating, outer coating, curing, post-treatment and other processes, made of water inside and outside coated plastic composite steel pipe, is the traditional steel plastic pipe, galvanized pipe upgrade type of cost-effective products. Products through the national chemical building materials testing center fire professional certification.

Stainless steel tee for pipe fittings, pipe connectors. Used in the main pipe to branch. Stainless steel tee has equal diameter and reduced diameter, equal diameter of the end of the pipe are the same size; The pipe size of the reduced tee is the same, while the pipe size of the branch is smaller than that of the main pipe.

Carbon steel elbow is a metal pipe that changes the direction of the pipe on a carbon steel pipe. The connection method is wired and welded. According to the Angle, there are 45° and 90°180° three most commonly used, and other abnormal Angle elbows such as 60° are also included according to engineering needs. Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The methods of connection with the pipe are: direct welding (the most commonly used way) flange connection, hot melt connection, electric melt connection, thread connection and socket connection. According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow and so on. Other names: 90 degree bend, right Angle bend, love and bend, etc.

1. Groove pipe connection technology, also known as clamp connection technology, has become the first technology of liquid and gas pipe connection, although the development time of this technology in China is later than that of foreign countries, but because of its advanced technology, it is soon accepted by the domestic market. From 1998 to the present, after a few years of development and application, it has gradually replaced the two traditional pipe connection methods of flange and welding. Not only is the technology more mature, the market is also widely recognized, and has been actively guided by national regulations and policies.
2. Grooved connection pipe fittings include two categories of products: (1) The pipe fittings that play the role of connection sealing have rigid joints, flexible joints, mechanical tees and grooved flanges; The pipe fittings that play the role of connecting the transition are elbows, three-way, four-way, reducing pipes, blind plates, etc.
3. The application of groove pipe fitting connection technology makes the complex pipe connection process simple, fast and convenient. A big step forward in pipe connection technology.
