Threaded couping is a common accessory in industrial pipe connection. It is mainly used to connect a short pipe of two pipes. It is a high-pressure pipe accessory formed by forging blank with round steel or steel ingot and then machining thread on lathe. The principle it uses is to clamp both ends of the steel pipe in both ends of the threaded pipe clamp.

Socket elbow is a high-pressure elbow pipe connection fitting, which is formed by die-forged billet of round steel or steel ingot and then processed by lathe. It is one of the forged socket series fittings. Socket elbow is composed of socket, socket, bending part and socket slot. It is characterized by socket slot on the socket, which is located at both ends of the bending part.

Socket Weld Flanges are flanges that are welded at the end and outside of the pipe by inserting the end of the pipe into the step of the flange ring. There are necked and non-necked. The necked pipe flange has good rigidity, small welding deformation and good sealing property.

Stainless steel is a kind of steel. Steel refers to steel which contains less than 2% carbon (C) and more than 2% iron. Alloy elements such as chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), molybdenum (Mo) are added to the steel during the smelting process to improve the performance of the steel and to make the steel corrosion resistant (i.e. not rusty), which is commonly referred to as stainless steel.

Reducing elbow is a pipe fitting used to connect two pipes with different diameters for turning. Reducing elbow is a pipe component with a design centerline radius of curvature that differs from the inner diameter of straight pipes at both ends. This allows it to connect pipes of different sizes in the piping system and provide smooth fluid passages at pipe turns. It is a production technology that uses a standard elbow blank to cut into a V-shaped elbow, and then applies pressure.

Threaded cap is a type of threaded pipe fittings, also known as plug. It is a high-pressure pipe fitting that is inserted on the pipe end to cover the pipe. It is used to close the pipe for the same purpose as pipe plug. It is formed by forging blank of round steel or steel ingot and then processed
