Installation Advantages of Press Fitting Technology
Press fitting systems eliminate traditional soldering and threading. Installation time reduces by 60% compared to conventional methods.
No flame or chemicals required during installation. This safety feature makes press fittings ideal for occupied buildings and sensitive environments.
The visual inspection window confirms proper installation. Green indicators show successful crimping, while red indicates incomplete connections.
Quality Assurance and Testing Protocols
Factory Testing Procedures
Every batch undergoes hydrostatic pressure testing at 2.5 times working pressure. Burst testing ensures safety margins exceed industry requirements.
Temperature cycling tests simulate decades of thermal expansion and contraction. Our quality lab maintains ISO 17025 accreditation for testing accuracy.
Certification Compliance
- GB-T 18992-2003 national standard
- ISO 15875 international compliance
- CE marking for European markets
- NSF certification for potable water systems
