Specifications and Controls
Specifications and Controls differ for the different types of construction of the Flanges and can be made available upon request. Raw materials and lay up sequences are defined and controlled. Pigments are not used unless specified by a clients specification.
All Flanges are subject to dimensional and visual controls. Glass content is checked by burn out tests and short term burst ratings are confirmed by destructive hydrostatic testing (minimum safety factor of 6). Qualification testing can include such tests as 1000 hrs at 2.5 times nominal pressure at 25°C.
