The expansion joint is divided into a single flange and a double flange expansion joint, the former is the side of the flange connection is welding. And the latter is a flange connection. Special attention should be paid to the after welding, the welding area to clean up should be, until leaking metallic luster, carefully check, avoid leakage occurred in the phenomenon of welding and weld.
1.single flange telescopic joint installation is simple and convenient, easy to install the valve, can bear the axial force of the pipeline. Installed in the vicinity of the pump valve, if the regular maintenance and maintenance of the pipeline, just pull down the nut on the expansion joints can be.
2.Single flange transmission force expansion device using metal casting or welding, the loose parts of the choice of trapezoidal rubber sealing ring, in the role of the gland and bolts using rubber compression principle of elastic deformation. Seal the sealing ring to the outer wall of the joint body. This can not only achieve the compensation of the axial displacement of the pipeline and can ensure that the active components of the original in the activity can achieve good sealing effect.
3.metal and sealing ring in strict accordance with the use of performance and user requirements. Material external coating high strength anti-corrosion paint material, each part of the connecting bolts for high strength carbon steel or stainless steel production. Because there is a gap between the body and the telescopic tube, so that the Dan Falan force expansion device has a certain axial and radial displacement.
Single sphere expansion joints in the pipeline can effectively compensate for the pipeline and the pipeline and the blind thrust, but also easy to pump,valve installation and maintenance replacement, is the most ideal pipe installation and operation of supporting products.
HuanZhong specializing in the production of telescopic device, advanced imported raw materials and equipment, first-class talent and technology,excellent product quality conforms to the national standards, products of each step through the strict inspection and testing,professional commitment pipeline industry for 30 years, quality worthy of your trust. HuanZhong pipeline equipment Co. Ltd. is looking forward to cooperate with you.
