Threaded Fittings | Phụ Kiện Ren Là Gì
What is Threaded Pipe Fitting
- Threaded fittings are used in non critical applications and when service fluid is at ambient temperatures such was instrument air, plant air, cooling water, potable water etc. As they do not require welding, they are used at places where welding is not permitted. Though ASME B16.11 provides dimensions for 1/8″ to 4″ size threaded fittings, normally in process plant, 1/2″ to 1-1/2″ fittings are used.

Advantages of Threaded Fittings
- Threaded joints can be easily made from pipe and fittings on site.
- They minimize fire hazard when installing in areas where flammable gases and liquids are present.
_______________________________________________
Disadvantages of Threaded Fittings
- Use of threaded joints is not permitted by ANSI B31.1 if sever erosion, crevice corrosion, shock or vibration is anticipated, nor at temperatures over 925 F.
- Chances of leakage are high with threaded joints.
- Seal welding may be required in more risky situations.
- For threaded joints, strength of pipe is reduced as forming the screw thread reduces the wall thickness.
