A. Compensator, expansion joint, expansion joints of pressure piping components belong to the category of special equipment, so should be paid attention to when purchasing the following:
1. Screening of manufacturers to choose qualified and have the production certificate (license) of the manufacturers.The manufacturer shall have factory to condition, equipment, testing equipment to meet the requirements, and have experience in the production of special equipment for many years.
2. When purchasing needs to provide manufacturers with the required compensator, expansion joint, expansion joints, complete data and requirements, such as: compensator, expansion joint, expansion joints, size, pressure, medium temperature compensation amount (also called pipe expansion amount) and connection mode and data.
3. Need to require producers receive customer data shall be provided to the user at the same time compensator, expansion joint, expansion joints complete product data (such as product calculation, design) for user reference and design department approval.That should be paid attention to and guide customers installation problems, make products to get the correct installation and use, can buy.
4. Incorrect installation can make corrugated compensator, expansion joint, expansion joints caused by bad, bring unnecessary losses to the user, so the pipe set has been design institute, the design of the rear can construction installation.
2. Compensator, expansion joint, expansion joints installation considerations:
1) compensator, installation of expansion joint, expansion joints shall be in accordance with the requirements for piping construction drawing and compensator installation instructions.
2) install the compensator, expansion joint, expansion joints of pipeline must be properly oriented and fixed compensator can play a role, thus guide and fixed bracket set must be strictly according to the relevant technical data of the design department.For guidance, the principle of fixed bracket setting, please see detailed "corrugated compensator installation".
3) compensator, expansion joint, expansion of frugality, corrugated pipe is made of thin stainless steel plate forming, so the transportation, be careful not to knock during assembly and welding, and makes such as scratch, arc, welding splash damage of corrugated pipe.
4) before installation should remove foreign bodies in corrugated pipe and pipe, ensure the normal movement of bellows.www.liweigroup.com
5) have to request for the compensator should be installed according to the requirements of the medium flow arrow.
6) in order to make the bellows are in good working condition, cannot be used when installing compensator, expansion joint, the deformation of the expansion joints including axial, lateral and torsional to reset piping installation error.
7) compensator, expansion joint, expansion joints installation after the crackdown, in front of the system is running to dismantle all transport fixed screw painted yellow.
