Failure Analysis, Manufacturing Evidence and Quality Control
Common misapplication risks: incorrect thread or connection standard, insufficient certified relieving capacity, unsuitable body or trim material, operating pressure too close to set pressure, unreviewed back pressure, and installation loads transferred to the valve.
Material review: body materials: Refinery-service carbon steel, alloy steel or stainless body according to A/TA model family and corrosion/temperature requirement. Trim and internals: Hard alloy trim and refinery-service internals selected by temperature, pressure and corrosion condition. Spring and stem: 50CrVA spring for standard service; stainless or coated fluoroplastic/304 spring options for corrosive service where specified.
Testing and inspection: Set pressure calibration, shell strength test, seat tightness/leakage test, reseating/blowdown check, dimensional inspection and material verification can be supplied according to the confirmed standard and order requirements.
Source and scope: product data is based on Zobai Safety Valve Product Catalog.pdf, catalog page 043-045. Project compliance remains subject to the approved datasheet, drawing, calculation and controlled certificates for the ordered configuration.
Review material traceability, type-test scope 和 project certificate requirements.
