All our housings are given stringent inspections during and after manufacturing including dimensional checks, weld inspections, surface measurements and hydrostatic testing. Each housing is labled by laser with a matching serial number on the bell and base. This serial number provides complete traceability for the Quality Control Certificate, Material Test Reports, and Weld Logs.
