金属松套式伸缩接头

产品适用范围

因为该系列产品属金属制品，其有较高的抗拉和抗压强度，软密封性能优越，装卸方便等功能，被广泛应用于电力，冶金，给排水和污水处理等行业，主要作用于水泵与阀门和管道之间的连接，它在管道运行中有一定的多向位移作用，可以缓解管道运行中的盲板推力，对管道起到一定的保护，特别是对管道的安装和维修提供了极大的便利，但是，在水泵出口处和管道转角处应采用传力接头，因为传力接头通过传力螺栓能把启泵时的盲板推力传导到泵和管道各部位，避免推力集中于管道或泵的近端，发生冲击力损伤设备。

Metal Loosing Expansion Joint

Product Performance

The product is manufactured through welding or metal casting, and the loosing part is sealed by echelon ring rubber. Operated by gland and bolt and based on the principle of rubber’s elastic deformation under pressure,the seal ring will be deformed and static seal will be done between joint body and expansion pipe wall. According to clients demand and product performance ,metal and seal ring mate-rials will be selected strictly. High –strength antifouling paint is painted outside and the joint bolt is made of high-strength carbon steel or stainless steel. Since there is some space between body and expansion., so axes and radial displacement will appear. Inside pipes, it becomes available to compensate and release pipe blind plate propulsion and makes it easy to maintain and change pump and valve. Therefore , it is an ideal matching product for pipes’ instal-lation and operation.

Applicable Scope

The metal product is functioned with pull and pressure resistance and excellent seal performance and easy installation. Hence it is widely used in power, metallurgy, drainage and sewage disposal to connect pump, valce and pipe, etc. It also has some multi-directional displacement during pipes’ operation so as to release blind plate propulsion and protect pipes, expecially it makes it easy to install and maintain pipes. However , force-transferring joints shall be used on the pipe corner and pump exit, because, the joints can transfer blind plate propulsion from pump start to pump and pipe through force—transferring bolt and prevent pull to ventralize close to pipe or pipe or damage equipment by impact force. Other joints can be selected freely for other position. Our tenet: your trust is our honor and we will manufacture high—quality products for you
