Petrochemistry
It is indeed fair to say that the vast network of pipelines used to carry different chemicals and liquids is the most important component of transportation in the developed world. There is another name for such pipelines that is “flow piping” that applies to the whole pipeline network that holds fluids such as air, steam, water, additives, gasoline, etc. within and around an industrial infrastructure that functions in the production of goods and services or power generation. The extreme temperatures of temperature and pressure will trigger the connection to leak. Hence the main requirement is to protect the joint adequately with fittings and flanges for corrosion and heat-resistant tubing.
5 of the Most Common Flange Types Used in the petrochemistry
Understanding joints, connections, and the most common flange types used in
the petrochemistry is a core requirement to keep these levels of safety and attitudes the same.
Weld Neck (WNRF)
Such flanges are common, and are used with a tapered center in high-pressure environments. In normal bending conditions the Weld Neck flanges are particularly useful.
Slip on (SORF)
A flange slipping over the pipe, welded in and out to improve the pressure and avoid leakage. A preference among engineers as opposed to the weld-neck because of its lower cost.
Lap joint
Apart from the slip-on, these flanges are slid over the valve but not fastened, which is used in combination with the bottom of a lap joint stub. Instead, the flange is held in place by the pressure exerted by the flange friction over the back of the pipe’s chest towards the gasket.
Threaded
If used in special circumstances, the threaded flange can be attached to the tubing without being welded. These are usually placed on deep-wall thickness tubes, used to create the inner string.
Blind (BLRF)
Most flanges are made without a screw, and are used in pressure vessels to blank off pipe ends, doors, and openings. These are also best suited for high pressure activities.
