Union Pipe Fitting/ Pipe Union Fitting

The pipe union joins fitting two pipes together and facilitates maintenance by turning only one pipe during disassembly. When joining pipes of different metals, pipe unions also prevent galvanic corrosion.

threaded union refers to a pipe connection with thread, which is the most common type of pipe fitting in industry and life. The threaded union makes the connection of the pipeline simpler and easier to disassemble and replace, which greatly saves the cost of the pipeline connection.

JIANZHI pipe union fitting is a black pipe fitting in marmalade, the most common pipe fitting in industry and life, with threaded pipe union. pipe union is a pipe fitting device that joins two pipes together and can be disassembled without causing any deformation to the pipes. pipe union makes the connection of pipes simpler and easier to disassemble and replace, saving significantly on pipeline pipe connection costs.

The pipe unions used in industry are usually made of high-pressure resistant metal, in materials such as marmalade.

JIANZHI is well known manufacturer of  Pipe Union fitting, consists of three parts: a nut, a female end and a male end. Our offered Threaded Pipe Union similar to a coupling, allows the convenient future disconnection of pipes for maintenance or fixture replacement. Threaded Reducing Union makes easy connection and disconnection, multiple times whenever we need.

Union pipe fitting, Male and Female, Conical Iron Seat is a kind of siren composed of internal thread siren slipknot and external thread siren slipknot. Pipe connection with two different threads. The internal and external thread pipes can be connected simultaneously. Generally, they are used in the parts that need maintenance and disassembly. In order to facilitate maintenance and disassembly, it is necessary to add a live connection in the pipeline as appropriate. Sirens are often used to connect two external joint pipes, which may be different Connection modes, quick connection pipe joint adopts the structure of two conical surfaces extruding each other, in order to achieve reliable sealing and connection advantages

Connection Advantages

1. High strength of threaded live joint: according to the principle of cold hardening of steel, the strength of straight thread rolling out of steel bar is greatly improved, so that the tensile strength of straight thread joint is higher than the tensile strength of steel bar base material.

2, Performance stability: the connection process is not affected by the quality of workers, so the performance is stable.

3, The connection speed is fast: because of the use of off-site prefabrication, on-site assembly connection way, so, the steel bar of the prefabricated wirehead can be prefabricated in large quantities in the steel bar yard. When the construction period is tight, only more assembly workers can be added to the construction site.

4, A wide range of applications: there is basically no restriction on the application model, more suitable for bending steel bars, fixed steel bars, steel cage, and other steel bars can not rotate the platform.

5, Easy to manage: there will be no mismatch between the sleeve and the reinforcement, and the inspection is more convenient. The operation is simple, ordinary workers after a few hours of learning can become skilled workers.

6. Significant economic and social benefits: shorten the construction period, improve the quality of the project, reduce energy consumption, conducive to environmental protection, reduce equipment investment, low additional costs, with obvious economic and social benefits.

7, Low labor intensity: processing a wire head only needs one step in a special wire rolling machine can be completed.


The union pipe fitting connects two pipes together and allows for easy maintenance by turning only one pipe when disassembling. When connecting pipes of different metals, union pipe fitting also prevent corrosion of the electrical coupling. union pipe fitting makes the connection of pipes simpler and easier to dismantle and replace, greatly saving the cost of connecting pipe connections.
