摘要： A method of forming a pipe joint between a pipe section and a pipe fitting includes inserting an end of the pipe section into a socket of the pipe fitting, and attaching a removable clamp to the pipe section and pipe fitting. The socket includes a centering device and a pipe stop that is configured to receive the end of the pipe section. The clamp includes a plurality of arcuate segments and a tightening mechanism, and each arcuate member has a removable/replaceable sealing member. The arcuate members are radially compressed via the tightening mechanism to cause the respective sealing members to seal an open end of the gap. A bonding agent is then injected into the gap via a port that extends through the pipe fitting. Once the bonding agent has been injected, the clamp is removed and can be reused.

摘要： A pipe fitting includes a socket that receives an end of a pipe section therein such that a gap exists between an outer surface of the pipe section and an inner surface of the socket. A pair of ports extend through the socket and are in fluid communication with the gap. A clamp secures the pipe section within the socket as a bonding agent is extruded into the gap via a port. The clamp includes a pair of arcuate segments, each having an inner circumferential wall, first and second end portions, and an elongated sealing member. Each arcuate segment includes a plurality of spring-loaded devices, each having a distal end portion extending through the inner circumferential wall that is urged into contact with the pipe section outer surface.
