Our company mainly produces cement pipe machine, cement pipe machinery, cement pipe equipment, cement well pipe machinery, cement culvert machinery, cement pipe, cement pipe machinery specialized cement pipe machine manufacturers, as we explain below cement pipe machine interface in the form of: 1. flat tube is produced cement concrete pipe machine interface in the form of a tube of the earliest manufacture small difficulty, high production efficiency, lower manufacturing costs, but it is poor sealing effect and seismic performance, So this way cement pipe machine interface used less and less. 2, socket interface in the form of rubber sealing ring seal, flexible connections, access door 80 an insertion depth 100Inln, interface relative angle 1.5 ", well this interface cement pipe making cement pipes seismic performance, installation speed fast, but large diameter concrete pipe socket type should not be used in connection door. 3, in the form of a flexible tongue and groove interface is mainly applied to the caliber ≥dl200 cement pipe. The interface is in the form of this interface in the form of a flexible connection, cement pipe machine When there are socket-type advantages, but for large diameter pipe, making good contact with the base tube body by force uniform load to bear, so safer to use. 4.18 www.wfzgj.com/ I plant to quality of survival, innovation good service is our aim, welcome to visit our friends, and seek common development prospects.
