The execution standard of the PTFE compensator
Aug 20,2025
The implementation standards of PTFE compensators mainly rely on national standardization documents and technical specifications. The following are the core standards and technical key points:
I. Current National Standards
GB/T 15700-2008 "PTFE bellows compensator"
It replaces the 1995 version of the standard and is applicable to thermal displacement compensation and vibration damping of corrosion-resistant piping systems .
Key parameters
Design temperature range: -50 to 180℃ (special requirements can be expanded by agreement) ;
Nominal pressure coverage: -0.01MPa to 1MPa.
Ii. Other relevant standards
GB/T 12777-2008 : general technical conditions for metal bellows compensators, with reference to for some technical aspects.
Industry application standards : such as the PN0.25-2.5MPa pressure rating and DN25-DN1600mm specifications in the chemical industry .
Iii. Comparison of International Standards
The EJMA standard of the United States : it focuses on metal compensators, but the trend of technology sharing is obvious .
JIS B 2352 : Specific requirements for corrosion-resistant compensators .
Note : In practical applications, it is necessary to select compliant products based on the working conditions and strictly follow the installation specifications (such as configuring guide brackets, avoiding mechanical damage, etc.) .
