Quality Inspection of Sock Filter Housing
FiltEdge requires strict quality inspection at every step of the process, from the raw material coming into the factory to your filter leaving the factory, to provide you with high quality filters.
- Strictly verifying the MTR report of the raw material and conducting ultrasonic thickness measurement on it to ensure that your filter base material is 100% up to standard.
- Perform color penetration testing (PT) on the core of the weld, and surface fine testing to eliminate micro-porous leakage and guarantee the smoothness of the inner wall to meet compliance requirements.
- Before leaving the factory, every Sock Filter Housing is double tested with 1.5 times water pressure and air pressure to ensure that your filter operates stably under extreme working conditions.
Certifications for Sock Filter Housing
Confirm applicable quality and compliance requirements for the selected product before ordering. Request supporting documents for the exact model, material and manufacturing entity. Food or pharmaceutical suitability, third-party inspection and any certification must be agreed separately; audit acceptance is not guaranteed.
