Marine flange welded seat GB/T 11693-2008 instead of GB/T 11693-1994, "ship flange welded single sided seat board" and GB/T 11694-1994 "marine flange welded double-sided seat plate".
The standard specifies the classification and marking, requirements, test methods, inspection rules, marking and packaging for the welded flange plates of ship flange based on GB/T 569 and GB/T 2501.
This standard is applicable to the design, manufacture and acceptance of ship's piping system for medium, which is air, distilled water, fresh water, sea water, lubricating oil, fuel oil and steam at temperatures not higher than 300 degrees.
Compared with GB/T 11693-1994 and GB/T 11694-1994, this standard has the following changes:
- adding forms for different types, different pressures, different paths, and the relationship between different materials and the applicable medium.
- - increasing the thickness series of the nominal pressure of 3.0MPa seat.
- - supplemented by test methods, inspection rules, signs, and packaging, etc.
