FRP pipes are connected using flanges; how to choose the fasteners
Thread Content
For fiberglass reinforced plastic pipes, how should fasteners be selected? A familiar friend is here to ask for some advice

What about the bolt length? About 10 years ago, in a project, the supervisor provided a calculation formula; as Excel was used to scroll down, the formula changed unintentionally, and the results displayed became much more numerous. The client wants the excess parts cut off, and the cost is around 100,000.
It depends on what standard is used for the flange; flanges made to different standards have varying thicknesses. When sizing it, the length = thickness of the two flanges + thickness of the gasket + thickness of the two flat washers + thickness of 1 spring washer + thickness of the nut + 2~3 thread pitches. If it is a double-headed bolt, the thickness of two nuts must be added
Are both flat washers and 1 spring washer necessary? I remember that at the time I seemed to have only considered flat washers
Check the requirements for the pipeline; those in conditions with vibrations are needed
Hehe, such a classic issue that arises when not paying attention to the dropdown in tables
