Heating pipe corrugated expansion joint installation instructions for use.

Heating pipeline corrugated expansion joint use are required to strengthen the pre-assembly, installation and completion of acceptance and other stages of operation: before assembly, the pipeline compensator appearance to carry out attentive inspection, and review the product quality certification documents, read the article assembly instructions for use.
 
During assembly, it is forbidden to punch, heat and hammer the outer barrel under pressure, and to minimize the deformation of the outer barrel under pressure to prevent jamming of the inner guide. To ensure that the pipeline at the installation of pipeline expansion joints parallelism error is less, it is imperative to lay the pipeline before assembling pipeline expansion joints, followed by cutting off the pipeline at the same length as the expansion joint in advance of preparing to assemble pipeline expansion joints, and then install the pipeline expansion joints, electric welding welding. Pipeline expansion joint lifting the whole process, lifting tools are prohibited to set on the pressure-bearing outer cylinder, should be lifted up at the preset lifting place. Prohibit the use of pipe expansion joint deformation method to adjust the error of the pipeline. When the hydraulic test, pipeline equipped with pipe expansion joint, before the support frame, guide bracket, sliding bracket, etc. are assembled according to the construction drawings, the system software hydraulic test shall not be carried out. If the pipe is straight through, the system software hydraulic test cannot be carried out before the pipeline is backfilled according to the design drawings.
 
Before carrying out the hydraulic test according to the section, should ensure that the support frame on both sides of the pipe section has sufficient compressive strength to ensure that the pipe section and the pipe complementary expansion joint. Pipeline hydraulic test using clean water, water chloride ion content of not more than 25PPm. pipeline compensator storage, use of the surrounding environment and gas medium can not have toxic substances that can cause the pipeline compensator leaching.
