Product introduction：

KRHD clamp flexible pipe joint products are welded. Although the welding process is not reduced, the number of bolts installed is greatly reduced compared to flanges, and the cost advantage is obvious for pipes with pressure of more than 10 kg. In other words, the price of 10 kg pipe is cheaper and the same grade flanges.

KRHD clamp type flexible pipe joint can be divided into steel ring type and pipe end type according to the construction form. The important difference between these two types of clamp type flexible pipe joint lies in the installation method and the use cost. Steel ring clamp joint is suitable for low pressure pipe and requires strict welding position.

According to the manufacturing process of clamp type flexible pipe joint, there are three kinds: casting, forging and steel. Casting clamp is formed as a whole, with high strength and hardness, and the content of molten steel can be adjusted according to demand. In addition, the corrosion resistance of casting parts is obviously better than that of steel plate. Forging is made of rolled steel forging into strip steel, and then rolled, this method has low cost, fast speed, the disadvantage is that the ear is easy to fall off under high strength for welding, not a body forming, steel is made of steel plate, compared with forging basically the same, the advantage is low cost, the disadvantage is the same as forging.

product feature：

Before installing the clamp flexible expansion joint, loosen the outer bolt and pull the product to the installation length. If used overhead, install the corresponding fixing supports at both ends. Other specifications can be produced separately.

Applicable scope Connection mode：

Realization of expansion of KRHD type clamp flexible pipe joint: The structure of the clamp flexible pipe joint enables each pipe joint to achieve certain expansion, and the amount of expansion can be met according to specific needs and different types. KRHD clamp type flexible pipe joint is widely used in coal, thermal power generation, hydroelectric power generation, petroleum, chemical industry, food processing, natural gas transmission, shipbuilding, cement pump truck, building fire protection, sewage treatment, paper and other industries.

Sealing principle of KRHD type clamp flexible pipe joint: KRHD type clamp flexible pipe joint has a unique sealing principle. Its unique C-type rubber sealing ring and unique connection mode make it have the sealing function of triple KRHD type clamp flexible pipe joint:

a, resealing rubber sealing ring itself with self-tightness, by its own elastic pressure on the pipe;

b. The rubber sealing ring will be further pressed after the tightening bolt is stuck on the resealing peripheral pipe;

c. When there is pressure in the third resealed pipe, the pressure will exert pressure on the C-shaped lip of the sealing ring from the inner cavity, so that the rubber sealing ring will press the pipe more tightly. The higher the pressure, the better the sealing performance.

Realization of the Angle of KRHD flexible pipe joint: Because the outer metal pipe clamp of the flexible pipe joint is not close to the pipe, there is a reasonable gap between the pipe and the pipe, so the pipe can produce a certain Angle.
