The main characteristics of the metal pipeline expansion joint is large compensation amount, high temperature resistance, high pressure resistance.

 

There are strict rules during installing dresser coupling dismantling joint, installation should pay attention to the fixed bracket set and stress, suppress not due to cracking the mounting bracket and cause telescopic unit telescopic end pull; otherwise the pipeline prone to problems. 

Paying attention to the guide bracket set distance, the first guide bracket should installed at a distance of 4D and the compensator (4 times), the second guide bracket should be installed at a distance from the compensator 14d; the third one can be set arbitrarily. Dresser coupling can alleviate the pipeline in the blind thrust plate, however, in the corner of the exit of the pump and pipeline, in the absence of fixed piers, infinite piers and directional limit a buttress support sliding pipe connection should use dowel joints and limit dismantling joint and avoid thrust was concentrated on the proximal end of the duct corner or pump, impacting damage to the equipment.

 

Actually in various pipelines usage, or the use of limited dresser dismantling joint, anti pull off limit rubber joints, pipe for the protection, especially in the installation and maintenance of pipeline provides great convenience.
