Threaded pipe fittings are used in a particularly wide range of fields, and there are many kinds. For most people, it is impossible to identify all kinds of threads clearly, and the classification of threads is not very clear. Therefore, mastering the basic knowledge of thread is helpful

The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe. It is also used in the equipment inlet and outlet flange, for the two equipment before the connection. Flange connection refers to the flange, gasket and bolt connected as a group of detachable sealing structure. Pipe flange refers to the pipe in the pipe flange, it is used in the import and export flange of the equipment. There are holes on the flange, the bolt makes the two flanges tightly connected, and the flange is sealed with a gasket. Because the flange has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, freezing, health, water heating, fire, power, aerospace, shipbuilding and other basic engineering.

ASTM A105 is an American Society for Testing and Materials standard specification for forging carbon steel for piping components. The composition, mechanical properties, tolerance and other standards of A105 are specified in detail. ASTM A105 is a mild steel material that is widely used

ASME B16.11 is the American Society of Mechanical Engineers standard for socket and threaded pipe fittings and includes detailed specifications for socket and threaded elbows. Socket elbow is a kind of high pressure elbow pipe connecting fittings which is formed by die forging round steel or steel

ASME/ANSI B16.5 Flange fittings are widely used in engineering design and involve a wide range of parts. It is an essential part of pipe design, pipe fitting valves, but also is necessary component for equipment and equipment parts (such as manholes, mirror liquid level meter, etc.) . Flange fittings have good strength and sealing, simple structure, low cost, can be repeatedly disassembled, and they are widely used in industrial furnace, thermal engineering, water supply and drainage, heating and ventilation, automatic control and other fields.

Why calculate the weight of the elbow？ In order to enable customers to choose a suitable mode of transportation, we generally provide customers with the weight of the elbow。 What is the steel pipe elbow?Elbow is the most commonly used pipe fitting in pipe installation,Its function is mainly to chang
