PRODUCT DESIGN

Pressure vessels are designed within code specified

stress limits. Design calculations, design prints and weld

qualifications are available for audit. All chamber branch

and circumferential weld joints are designed to achieve

FULL penetration.

WELDING

All welding is performed by qualified welders and per

procedures required by the ASME Boiler Pressure Vessel

Code Sec. IX. Welds are visually inspected for FULL

penetration. All other non-destructive examination is

performed per ANSI B31.1.

MATERIALS OF CONSTRUCTION

All pressure-retaining materials are procured with

Certificates of Conformance to assure compliance of

components with required standards.

HYDROSTATIC TEST

All chambers are hydrostatically tested at 1.5 times the

design pressure.
