• Rated pressure up to 300psi / 2.5Mpa;
• National patent applications, dual buckle design makes installation easier and provides better rigidity;
• Applications: rigid clamp connection system does not have a flexible manner, after clamping with pipe clamps to form a rigid one, larger span in the spreader, and the pipe connection on
• their own rigid support.

2. 3.5MPa rigid couplings

• Cross-shaped rib structure design;
• Provide sufficient rigidity, no expansion, contraction or angular deflection;
• Than the wire, welding and other connections reduce installation time up to 60%;
• Rated pressure up to 500psi / 3.5Mpa;
• Applications: for pressure, spreader span occasions.

3. The flexible grooved couplings Features

• Provide expansion and contraction of the elastic deflection angle;
• Rated pressure up to 300psi / 2.5Mpa;
• Leaving a gap between two steel pipe ends to accommodate the expansion of the pipeline shrinkage. Clamps at the maximum allowable deflection misaligned should maintain normal
• operating pressure. Having the ability to withstand a certain load terminal. End load refers clamp mount along the pipe can withstand axial load capacityMainly used mainly applied to conveying pressure medium line can not ensure concentricity of places, such as fire sprinkler systems, water supply systems, gas pipelines.

4. Adjustable flexible grooved couplings

• Having sufficient strength;
• Applied concentric necking competent;
• Designed to replace two joints and a reduced diameter tube;
• Rated pressure up to 300psi / 2.5Mpa;

5. The short pipe flanges:

The tube and the tube connected to each other with flange valves and other components connected to the pipe end. There are holes on the flange bolts so that the two flanges tightly connected. Flange sealing gasket. Flange tube pipe with finger flange. Flange connection by a pair of flanges, a gasket and a number of bolts and nuts. Spacer placed between two flange sealing surface, tighten the nut over the gasket surface deformation after pressure reaches a certain value, and fill the sealing surface uneven, so that the coupling does not leak tight.

6. Reducing fittings

It used to connect pipes of different sizes; generally it is divided into two kinds of concentric pipe reducer and eccentric reducer, when the rear projection diameter pipe stand up two ports are concentric circles, it is called concentric reducer, eccentric and diameter pipe is cut to cylindrical projection within the small circle.

The connector can be divided into the form of a trench diameter pipe and threaded diameter pipe diameter pipe depending on the environment, the surface treatment can be selected resin coating, hot-dip zinc, dipping, Dacromet processing.

7. Three

Tee for the pipe fittings, pipe fittings, used in the main pipe to the branch pipes place.

There are two tee, straight tee and reducing tees. Take over the ends Tee are the same size; the same size – Reducing tee competent to take over, and over size is smaller than the head of the branch pipe over size

8. N Stone

Stone is a common pipe conduit elements, only two-way, four-way Equal and Reducing Cross. Equal Stone is the same size as four ports; Reducing Stone is a period in charge plus two small branch pipe, two large size is in charge, indirectly out of two small size is manifold.

9. Mechanical tee

Main features and uses

Any position on the pipeline can provide a T-shaped opening of the branch pipe connecting;
2. The trench may be provided with threaded connections

3. The connection can be a flexible tool, with seismic, anti-shrinkage, expansion capability.

Fast and easy to install pipes, pipe during installation allows a certain degree of deflection dislocation, easy to adapt to external deformation of steel structure of the main building, the piping system to ensure security is not compromised.
5. Due to mechanical tee directly in charge of the opening, thus saving a tee and three joints, significant savings in construction costs;

Applications: Three can be used directly on the pipe connected to the manifold. First on the pipe with a hole tapping machine, and then the mechanical tee snaps into the hole, the hole is sealed by a seal along the wall four weeks. Mechanical tee devillicate pick whip manifold manner and with a groove connected manifold ways. Then take out the way wire tapered pipe thread connections, standards are divided NPT, BSPT or Chinese standard GB7306. Connections for connecting pipe, fire protection piping systems, industrial water and chemical transport.

10. A mechanical four-way

A combination of the upper part of the two mechanical tee, easy to use and flexible, can be used instead Reducing Stone used under certain conditions, depending on the combination of mechanical tee can be combined trench mechanical four-way, four mechanical wire connection through the groove Reducing Stone machinery, mechanical wire connection Reducing Stone, Stone wire connection trenches machinery, wire connected to different forms of groove Reducing Stone and other machinery. Due to mechanical tee directly in charge of the opening, thus saving a four-way and four joints, significant savings in construction costs; machinery Stone higher quality holes, two requirements must be positive hole centers, or vulnerable caused by pipeline leaks. Due to the mechanical construction in Stone opened on the main channel of the same cross-section two holes, and therefore a greater impact on the strength of the main channel, so the construction required mechanical four-way branch pipe diameter smaller than the diameter of three competent level and above. Depending on the environment, the surface treatment can be selected resin coating, hot-dip zinc, dipping, Dacromet processing.

11. Bend:

In the piping system, the elbow is to change the direction of the pipe fittings. Angularly points, 45 °, 90 ° most common, according to project needs also include additional 11.25 °, 22.5 ° and other non-normal angle elbow. Since the elbow has a good overall performance, so it is widely used in chemical, construction, water supply, drainage, oil, light and heavy industrial, refrigeration, sanitation, plumbing, fire, electricity, aerospace, shipbuilding and other infrastructure projects.

Depending on the environment, the pipe trench surface treatment can be selected resin coating, hot-dip zinc, dipping, Dacromet processing.
