Threaded flange is a non-welded flange that is made by processing the inner hole of the flange into pipe threads and matching with the threaded pipe to achieve connection. The connection method is to match the inner hole of the flange with the thread on the pipe, and then rotate and connect them together.

MSS SP – 97 weldolet is a pipe fitting used for branch pipe connection in pipeline system.It plays an important role in pipeline engineering in many industrial fields such as petroleum, chemical, electric power, shipbuilding, etc.

A420 WPL6 tee is a pipe fitting with three ports, mainly used to divide a pipe into two branches or merge two branches into one pipe. Common ones are equal diameter tees and reducing tees. In the layout of the pipeline system, the structure of the tee can flexibly change the flow direction of the fluid to achieve the function of branching or merging.

A182 F316 hex nipples are short nipples made of stainless steel and have a hexagonal structure. This type of nipples plays a key role in pipeline connections and can meet the needs of different pipeline designs. Common types of stainless steel hexagonal nipples include equal-diameter hexagonal nipples and reducing-diameter hexagonal nipples.

A234 WPB blind flange is a type of flange widely used in pipeline systems. A234 is the standard number of the American Society for Testing and Materials (ASTM), and WPB indicates that this material is a carbon steel pipeline component for medium and low temperatures.

The stub end is usually a short section of pipe fittings, with one end being a flap structure, and the other end can be a stub end or special processing according to specific needs. The turning part is designed to facilitate the connection with other pipe fittings or equipment.

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.
