Product description

Groove connection technology, also known as clamp connection technology, because of its advanced technology, quickly accepted by the domestic and foreign markets, has gradually replaced the flange and welding of the two traditional pipe connection. Not only is the technology more mature, the market is also generally recognised, and has been actively guided by national regulations and policies. The application of groove connection technology, so that the complex pipeline connection process has become simple, fast and convenient, so that the pipeline connection technology has taken a big step forward.

Customer challenge

Traditional threaded connection, the need for on-site processing of threads, construction inconvenience;

Traditional welding connection, welding slag, fume pollution, the need for high construction and installation qualifications, construction is very inconvenient, the project delivery cycle is long, high cost; 3. Traditional welding, flange connection, low installation efficiency, high installation costs, long construction period, dismantling and maintenance complex;

Traditional welding, flange connection, low installation efficiency, high installation costs, long construction period, dismantling and maintenance complex;

Traditional flange connection, requires a large installation space, can not be installed in a small space;

Traditional welding, flange connection, for the rigid connection, can not solve the pipeline thermal expansion and contraction, pipe settlement and other issues.

Product function

Safe and reliable performance

Noise Reduction Function

Shock-absorbing function

Quick-fit

Anti-bump function

Environmental protection function

We are the only factory in China that has four certificates of FM, UL, LPCB and VdS at the same time, and also the company with the most complete specification of 3C certification in China. Pressure levels from 225psi to 750psi can meet your choice for different pressure levels.

Adopting rubber ring sealing, the rubber sealing ring has elasticity, which can effectively alleviate the vibration and greatly reduce the noise.

The reserved pipe end gap effectively solves the thermal expansion and contraction of the pipeline and compensates for the pipe settlement.

Easy disassembly and maintenance, easy replacement of pipe fittings, especially our quick-fit series, the installation speed is increased by 10 times.

High mechanical strength, strong pressure-bearing capacity, bump resistance.

The surface treatment of bolt and nut is trivalent chromium treatment, environmental protection and no pollution; on-site installation of environmental protection, no welding slag, smoke and dust pollution.

Value advantage

Corrosion resistance

The surface of the casting can be anti-corrosion treatment by electrophoretic paint, plastic spraying, hot-dip galvanising and so on;
Easy maintenance

Ggood system stability, easy maintenance, groove fittings connection with unique flexible features, so that the pipeline has the ability to resist vibration, shrinkage and expansion, compared with welding and flange connection, the stability of the piping system to increase more suitable for temperature changes, thereby protecting the pipeline valve, but also reduces the pipeline stress on the destruction of structural components.
Easy to install

Groove fittings connection operation is very simple, no special professional skills, ordinary workers can operate after simple training; the required operating space is small, can really achieve the wall corner installation, the operating difficulty is greatly reduced, thus saving the floor space, beautify the pipeline installation effect!
Construction safety

With grooved pipe fittings connection technology, the site only needs cutting machine, rolling groove machine and tightening bolts with wrenches, construction organisation is convenient, no need for open fire treatment.
Economic benefits

Grooved pipe fittings connection operation is simple, labour-saving and time-saving, so it has good economic effect.
