Ductile Iron Grooved Pipe Fittings and Couplings

Foring clamp steel quick locking is used for pipe connections, reliable performance, easy to install products.

(also called steel flexible joint, clamp) is a kind of flexible joint pipe connector, reliable performance, convenient installation products. Flexible joint at low pressure, the deformation on the sealing ring to seal the objective, elastic, flexible joint in pressure increases, the role of the media in the sealing ring, steel flexible joints to automatic sealing function, and the displacement and bending clearance compensation pipeline due to thermal expansion and contraction of the left in the roomBefore the installation of connector, the first end pipe welded on both ends of pipeline, practice is: remove the bolts, the clamp is opened, the end pipe installed in accordance with the technical parameters of the corresponding pipe length fixed at both ends of the tube, adjust the parallelism, welding. B. mounted rubber ring and boltEnd pipe according to the above method after installation, after cooling, the sealing ring is arranged in the middle of two ends of the pipeline shown according to the diagram. The procedure is as follows: first, the rubber ring sealing surface in turn, will turn to the outside, and then put into one end of the tube, is adjusted to the appropriate position, then the ring edge up, buckle cover at the other end of pipe, adjust the sealing ring on both ends of pipe position, should make the sealing ring in the middle of two end tube. For the convenience of apron successfully installed can try to ring side turn up and smearing Vaseline oil. Then put the clamps split button on the end pipe, bolt the wild card is fixed, should pay attention to: the application of bolt fastening diagonal method at the same time gradually alternately, fastening bolts at the same time, application of hammer wild card, so that the sealing ring is coated evenly, can avoid the interface card on the extrusion distortion phenomenon of sealing ring. After the completion of welding repair of the sealing surface should be removed or burr, bumps, scratches and dirt, and then spray antirust paint.
