PRODUCTS DETAILS:

Steel pipe fittings have the characteristics of reliable and safe connection, convenient and fast construction, suitable for embedded installation, maintenance-free update, and relatively superior economy. The working principle of the carbon steel press fittings is to insert the galvanized pipe into the bearing of the pressed pipe fittings, and use special pressing tools to jam the galvanized pipe in the pipe fittings, and the cross-sectional shape of the clamping place is hexagonal, and there is an O-ring seal between the carbon steel pipe and the pipe fittings, so that it has the characteristics of anti-leakage, anti-pulling, anti-vibration and high pressure resistance. Widely used in water plants, fire protection systems, chemical plants, paper mills, beverage factories, electronics factories, daily chemical plants, pharmaceutical factories, supporting machinery suppliers and other enterprise fields.

The working principle of Steel Press Fittings Coupling diameter docking coupling (DDS coupling) is to put the stainless steel forged fittings to be transported into the bearing interface of the press-type pipe fittings of the corresponding specification, and then the special pressing tool will kill the carbon steel pipe inside, and then add a sealing ring to the sealing place to prevent the medium from leaking.

Long coupling ,Slim Coupling is a kind of connection with bearing pipe fittings with special sealing rings, and presses the pipe mouth with special tools to play a sealing and fixing role, which is divided into D type and S type according to the end pressing connection method. It has the characteristics of anti-pulling, anti-rotation, simple and convenient installation, small operating space required, earthquake resistance, and maintenance-free after installation.

The reducer Coupling ,The surface of the reducer pair is selected from Dacromet, which can obtain anti-corrosion performance similar to hot-dip galvanizing, and generally can obtain the anti-corrosion performance of neutral salt spray test of more than 500h, while the blue zinc plating bolt used in fire protection is generally only 48~72h neutral salt spray test; The neutral salt spray test of epoxy coating of grooved pipe fittings with coating thickness of 60~100μm is generally about 72h.
