Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is used in the following industrial products
A sealed container designed to hold fluids at a pressure substantially different from the ambient pressure, serving as the core housing for reverse osmosis membrane elements.
The primary pressure-containing structure of an ammonia oxidation reactor that houses the catalyst bed and reaction zone.

Primary failure modes include buckling under external pressure, fatigue cracking at weld joints, corrosion-induced thinning, stress corrosion cracking, and plastic collapse from overpressure.
Thickness is calculated using ASME BPVC formulas considering design pressure, material allowable stress, joint efficiency, corrosion allowance, and minimum required thickness for structural stability.
Ultrasonic testing (UT) for thickness measurement, radiographic testing (RT) for weld quality, magnetic particle testing (MT) for surface cracks, and hydrostatic pressure testing for leak verification.
