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 nondestructive examination
is performed per ASME B31.1.
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; and 5% radiographic inspection of
weld is performed per ASME B31.3.
MATERIALS OF
CONSTRUCTION
All pressure-retaining materials are procured with
Certificates of Conformance to assure compliance of
components with required standards. Chrome-Moly
models are post-weld heat-treated.

All welding is performed by qualified welders and per
procedures required by the ASME Boiler Pressure
Vessel Code Sec. IX. Carbon steel pressure boundary
parts are post weld stress relieved. All welds and heat
affected zones are hardness tested to ensure compli-
ance with NACE maximum hardness requirements.
MATERIALS OF
CONSTRUCTION
Only NACE listed materials are used for pressure retain-
ing parts. Certificates of Conformance assure compliance
of components to required material standards.
