Nowadays, many industries supply steel material according to customer requirements. They provide a wide range of materials such as steel joints, bolts, chains, rubber sheet, and types of flanges like 10k (which is also known as ประเภทของครีบเช่น 10k in the Thai language), 16k, blind flanges or others.

A flange connects the pipes, valves, pumps, and other equipment to form a piping system. It also provides easy access for cleaning, inspection, or modification.  Besides, the flange made up of forged material or cast steel rings as well specially designed to connect two equipment. However, the classification of steel pipe flanges defines according to their standard sizes.

Plumbers mostly use these flanges for various purposes and the piping system. Today, the metal industry mostly supplies two types of flanges in large quantities. It is Weld Neck Flange and Lap Joint Flange: –

Weld Neck Flange: Weld neck flanges are visually different from the other flange types with long tapered hub and smooth transitions from the thickness of the extent to which the butt weld is joining a pipe or fitting. It is usually used in severe service conditions, whether loading conditions are substantially constant or fluctuate between wide limits.

Lap joint Flange: A Lap Joint Flange use in conjunction with which the stub end flange, which slips on the stub end fitting and appropriately connected to the pipe or other fittings by welding or other mechanical means.

Similarly, many other types of flanges are available and all have different properties sizes and use for various purposes. Thus, flanges are critical for many purposes for especially in the plumbing system.
