Three types of tube fittings

Tube fittings join pipes and tubing throughout a system. Choosing the ideal fitting connection reduces leakage, which can cause high operating expenditures and increased downtime. There are three main types of tube fittings: flare fittings, mechanical grip-type fittings, and bite-type tube fittings. Each has its own unique strengths and weaknesses, duplex steel fittings manufacturers said.

Flare fittings typically consists of three components: nut, sleeve and body with a flared or conical end. The tube fits inside of the flared end, providing a deep seal. Special flaring tools are required for installation, but the fittings are available in a variety of materials. Flare fittings can handle higher pressures than compression fittings, but may produce stress risers and cracks on brittle or thin tubing.

Mechanical grip-type fittings consist of a nut, the body and two ferrules. The back ferrule grips the tubing while pressing up against the front ferrule, which spring-loads the front ferrule and creates a seal between the tubing and the fitting body. Mechanical grip seals can be made and re-made multiple times without damaging the fitting components or the tubing. They are available in a variety of materials and are highly resistant to mechanical vibration. duplex steel flange supplies

Bite-type fittings consist of a nut, the body and a ferrule with a sharp leading edge that "bites" into the skin of the tubing to produce a seal that can withstand high pressures. Bite-type fittings are available in single and twin-ferrule types. The latter is more reliable because the back ferrule grips the tubing while the front ferrule provides the seal. In the single-ferrule model, the ferrule must function as both the grip and the seal. stainless steel forged flanges Wholesale
