1.Raw Material Inspection & CuttingQualified SS304/SS316 stainless steel bars are adopted. Spectroscopic test is carried out for incoming materials to verify mechanical and anti-corrosion performance. Bars are precisely cut into blanks with tight length tolerance.
2.CNC Integrated TurningCNC lathes machine the fitting body in one piece, processing inner bore, sealing cones and hexagonal positions accurately to guarantee high coaxiality and eliminate leakage risks under high pressure.
3.Precision Machining of Double FerrulesFront and back ferrules are separately turned with precise cutting edge angle, which can tightly bite tube walls to form double sealing structure after assembly.
4.Mirror Polishing & PassivationMulti-step polishing removes burrs and tool marks. Passivation treatment forms a protective film to strengthen acid, alkali and seawater resistance for harsh working environments.
5.Batch Pressure & Air Tightness TestRandom sampling for air tightness and burst pressure test simulates real pipeline working conditions to filter out defective products and ensure reliable sealing performance.
6.Final Dimension Inspection & PackagingAll sizes and appearance are double checked. Qualified fittings are packed with moisture-proof bags to prevent scratches during transportation, complete with material test certificates for shipment.
