Surface treatment: corrosion-resistant treatment such as plastic spraying/dipping paint/galvanizing

Packing: wooden box

Freight method: use DHL, FedEx, EMS when the goods are small, and use sea  when the goods are large

Payment method: T/T, money gram, L/C, Western union

Application range:  water supply, mine pipeline, etc.

The channel type ultra-high pressure pipe joint is suitable for mining, Marine and other high pressure pipe system.

It is a two-grooved pipe coupling that can withstand 40Mpa of pressure.

The shell is made of ductile iron, according to ASTM A536 65-45-12

The rubber gasket has a special design with “C” profile that creates an effective seal in three steps:

When assembling stretched rubber gasket that is slightly smaller than a pipe diameter of the two pipe ends and create a first seal.

The coupling halves are then placed around the gasket which adapts to them. The coupling halves are bolted together to further improve the sealing.

When the piping system is pressurized, a ”pressure reserve” is created due to the profile of the gasket. The sealing lips are pressed at the increasing pressure harder down against the gasket seating surface which creates the third seal and makes the connection completely leak-proof and airtight.

Working temperature of the gaskets is -34°C to +110°C.


Safety performance: groove connection mode, automatic precision casting or precision forging forming, high dimensional accuracy, excellent physical properties, safer use.

Weight reduction: The same 89 mm connector can reduce the weight by 50% compared to the flange connection.

Save time: The number of bolts and nuts in the grooved steel pipe connector is reduced compared with the flange, greatly reducing the installation steps.

Space saving: No flanges take up less space, and more pipes can be installed in the same space
