API 5L galvanized pipe is a pipe with a layer of zinc on the surface of the steel pipe. The presence of the zinc layer gives the galvanized pipe good corrosion resistance. The chemical properties of zinc are more active than iron. In a corrosive environment, zinc will oxidize before iron, thereby protecting the steel pipe matrix from corrosion.

The connection method of A182 F11 socket flange is to insert the pipe into the socket of the flange, and then seal it with welding or use a sealing gasket. This connection method is relatively strong and can adapt to the thermal expansion and contraction of the pipe to a certain extent.

S31803 90 degree elbow is a kind of stainless steel with two-phase structure of ferrite and austenite. It combines the high strength of ferritic stainless steel with the good toughness and corrosion resistance of austenitic stainless steel.

A105 FF slip on flange is a commonly used pipeline connection element, mainly made of carbon steel, and connected to pipelines or other flanges by flat welding. The structure of the slip on flange is relatively simple.

A106 seamless steel pipe is a seamless steel pipe produced in accordance with the American Society for Testing and Materials (ASTM) standard A106. This standard specifies the material, size, manufacturing process, mechanical properties and other requirements of steel pipes, aiming to ensure the quality and reliability of steel pipes in various industrial applications.

 NPT A105 bushing is mainly used to connect two pipes of different diameters in the pipeline system or to correct the error in the pipeline installation. It is usually made of A105 carbon steel, has high strength and good corrosion resistance, and can withstand high working pressure.

ASME B16.9 cross is a pipe fitting used to connect four pipes together, and the connection is achieved by welding. It plays a role in diversion or confluence in the pipeline system and is an important connector in the pipeline layout.

Stainless steel lap joint flange is a flange connection component, which consists of a flange, a flanged short section or a butt welding ring. Among them, the flange is made of stainless steel, which has good corrosion resistance, heat resistance and other properties.

The butt welded eccentric reducer is a pipe fitting used to connect pipes of different diameters, and its central axes do not overlap, and there is an eccentricity.

socket pipe fittings are a commonly used type of pipe fittings. The main feature is the socket structure.It consists of a socket and a spigot.

A790 duplex stainless steel pipe is a special type of stainless steel pipe, whose microstructure is mainly composed of austenite and ferrite.

The spectacle blind flange is named because its shape resembles the number “8”. One end is a blind and the other end is an iron ring. However, the diameter of the throttling ring is the same as the diameter of the pipe and does not play a throttling role. This design makes the spectacle blind flange uniquely flexible and practical in the pipeline system.

2”90°stainless steel elbow is a commonly used pipe fitting in the pipeline system. It is mainly used to change the direction of the pipeline, make the pipeline turn 90°, and connect two pipes with the same or different nominal diameters.

Carbon steel threaded half-coupling is made of carbon steel material, with a half-threaded interface coupling. It is mainly used to connect the pipes to ensure the smooth flow of fluid in the pipeline system.

Alloy steel butt-weld pipe caps are mainly used to close pipeline systems to ensure that the fluid in the pipeline will not leak.It is usually welded at the end of the pipeline to provide a reliable sealing effect.

Class 150 F316 slip on flange is a common pipe connection element, mainly made of stainless steel material, through slip on and pipe or other flanges are connected. slip on flange is generally composed of flange plate, bolt hole and sealing surface.

Socket weld union,is a pipe connector connected by socket welding. Socket weld  union mainly consists of a socket, a socket and a socket slot. It is characterized in that there is a socket slot on the socket, and the socket and the socket are located at both ends.

ASTM A350 LF2 is a low temperature carbon steel material, mainly used to manufacture flanges and other connectors. This material has good low temperature performance and corrosion resistance, and is suitable for use in low or ultra-low temperature environments.

Carbon steel butt welding 90 degree elbow is a connector specially designed for use in piping systems. Its main function is to create a 90 degree turn in the pipe so that the fluid can flow along a predetermined path.

Carbon steel threaded tee is a pipe connector made of carbon steel material, with three threaded interfaces, used to connect three pipes, one of which is used as a branch port. It realizes the medium diversion in the pipeline system and ensures the normal operation of the pipeline system.

Stainless steel socket flanges are installed during pipeline construction and connected to another pipeline through bolts to achieve a tight connection of the pipeline.
