China Konch Gas Stainless Steel Corrugated Flexible Metal Hose
Fracture occurs in the vibration test of the safety valve tubing assembly after assembling with the whole machine,
which seriously affects the reliability of the product. Through the examination and analysis, to determine the cause
of the fault, and through improving the structure design, formulate a reasonable processing technology plan,
to avoid the recurrence of such a fault.
Common faults of pulse safety valve are: valve body surface leakage, the main valve does not act, the main valve
seat time is long, the seat pressure is low, frequency jump and flutter. Based on the analysis of the cause of the fault,
the corresponding solutions are given.
Product Features
1. High-quality imported 304 stainless steel, with nickel content ≥8.0%, over 50 years of service life of the
stainless-steel pipe body.
2. Deeper and denser corrugation, with better flexibility and safety.
3. Integrated pipe fittings and pipes, making the installation easier and faster;
4. Short and hidden tube neck inside the tube, good protected and invulnerable to damage
