Refining and Chemical Flange Bolting

Flange bolts have a multitude of different uses. They generally have a skirt surrounding the bolt head. The purpose of this skirt is to distribute the load evenly across the surface. The inherent design of the flange bolt is meant to give it the same advantages that a belleville disc spring or another holding washer would give you. Although you won't need a washer with your flange bolt, you'll still have to take the same worries into consideration such as plating and materials. Flange bolts are the main fastener in refining and chemical flange bolting. Whatever your application is, the bolt is meant to provide a safe, leak-free seal on your joints, petrocehmical pumps or valves. Whether you're in the petrochemical business or you're looking for cryogenic flange bolting, flanges are the way to go.

Cryogenic Flange Bolting

The distribution, use, and storage of LNG (liquid natural gas) requires very specialized, leak-free equipment. Cryogenic flange bolting, valves, and joints, are the special equipment that is needed to maintain a reliable environment in the world of cryogenics. Most equipment designed for cryogenic handling is made from stainless steel and is fire safe. Made to a DIN spec, cryogenic flanges will provide a safe working environment for workers dealing with liquid natural gas.

The DIN Spec

Not all, but many flanges are made to a certain specification. This is called the DIN spec, and allows more common and controlled usages of flanges or belleville springs. It allows for a large quantity of them to be produced to a customer's desire. The only variable aside from the DIN (which will designate the type of flange or washer) is the plating and material it is made out of which will determine other properties. Whether your application is for refining and chemical flange bolting or you need belleville disc springs, this specification will allow you to get your items quickly and easily, without unnecessary measurements.
