Introduction to welded pipe fittings
Definition & Manufacturing: Butt-weld fittings primarily refer to pipe fittings connected via welding. Manufacturing typically follows two paths: Path 1: The fitting manufacturer uses welded pipes conforming to standards as raw material. These are formed into the required shapes (e.g., elbows, tees) through cold/hot forming processes (e.g., pushing, pressing, bending). This forming process itself does not include welding operations; […]
RND PLUG THD-M
Welding plugs are used to block holes by welding, without the need for adhesive bonding, achieving water tightness and beautiful appearance, and easy to operate. There are four types of plugs: square plugs, hexagonal plugs, and round plugs. The implementation standards include ANSIB16.11, GB/T14383, and BS3799 plugs, also known as pipe caps, caps, pipe covers, […]
BULL PLUG
Convex head plug (also known as head, pipe cap, or blind head): a pipe fitting used to permanently or temporarily seal pipeline ports, achieving sealing through welding or threaded connections to prevent medium leakage. Core function: Replace traditional pipe plugs and install directly on the pipe end without the need for additional connectors, simplifying the […]
CON SWAGE PBE
Basic concepts Concentric Swaged Nipple: Belonging to the category of reducing pipes, it is used to connect two pipes of different diameters, with their centerlines coinciding. When the fluid passes through, the flow direction is symmetrical and the resistance is small. Both Ends Plain (BEP): Refers to pipe fittings with flat ends at both ends, […]
SQ CAP THD-F AND HEX CAP THD-F
Four sided threaded pipe cap Definition: Also known as square plug or square tube cap, it is used to close square or rectangular tube ports and is fixed by threading or inserting a hook. Function: Protect the edge of the pipe mouth, prevent dust and leakage, decorate and beautify, reduce noise and slip. hexagon cap […]
SQ PLUG THD-M
Square plug (square tube plug/square tube cap) is a type of pipe fitting used to close square or rectangular tube ports, with core functions including: Protective: Block the edge of sharp pipe openings to prevent foreign objects from entering or personnel from scratching. Sealing: Avoid dust and liquid infiltration (some parts are designed with rubber […]
NIPPLE TBE THD-M
Double Threaded Nipple is a type of pipe fitting connection with external threads machined on both ends, used for quick docking of pipes of the same or different diameters, commonly known as “Nipple” in English. Its core function is to achieve pipeline extension, diameter reduction, or equipment interface conversion through threaded connections, and it is […]
FULL COUPLING SW
Basic definition Double Socket Pipe Coupling is a type of pipe fitting with socket interfaces at both ends, used to connect pipes of the same or different diameters. Its core function is to achieve pipeline docking through socket welding or rubber ring sealing, and it is widely used in fields such as chemical engineering, energy, […]
NIPPLE PBE
NU Pup Joint is a short pipe component with flat threads at both ends (i.e. without thickened threads), mainly used to connect tubing, casing, or downhole tools of the same or variable diameter. Its core feature is that the threaded end has not been thickened (different from the EUE thickened type), so the wall thickness […]
