Different Characteristics of Pipe Cap

NPT (National Pipe Thread) size: This characteristic is appropriate for caps with a round form when the item that has to be protected has a male NPT thread.

BSP (British Standard Pipe) size: This size choice is only appropriate for caps with a round form and a male BSP thread on the item to be capped.

Diameter: Only round caps and plugs may be made with this crucial size. The primary thread diameter is the most crucial factor to take into account when fittings have straight threads. However, when a cap, plug, or item to be capped has a tapered (NPT or BSP) thread, its size is not a crucial factor to take into account.

Shape: The size and shape of pipe caps are other crucial factors to take into account. distinct pipe caps have distinct features. Features include:
· Round Caps: The flange, slotted head, knurled or faceted head, retaining head, and tear tab are all common characteristics of round caps. A flange is designed to make it simple to remove pipes or tubes or to provide additional protection. Additionally, flanges aid in preventing inadvertent plug ejection through the aperture. A screwdriver makes it simple to put on or take off slotted caps.
· Square or Rectangular Cap: When choosing a square or rectangular cap, the length and breadth should be taken into account the most. For square caps, the length and breadth are the same dimension, but the width is the smaller cross sectional measurement for rectangular caps.

Surface Treatment of Pipe Caps

In order to determine whether the hardness standard of carbon steel pipes after heat treatment meets the requirements, a hardness test is required. Hardness testing methods include Rockwell hardness test, Vickers hardness test, Brinell hardness test, etc. Among them, Brinell hardness test is the most commonly used testing method.

 

Brinell hardness testing is usually measured using a Brinell hardness tester. The material needs to be flattened before measurement and calibrated before testing. When testing, the hardness tester needs to be pressed on the surface of the material to be tested, and it generally needs to be kept stable for 10 to 15 seconds. The hardness tester will rotate the pointer according to the pressure and display the hardness value.

Usage of Pipe Cap

Pipe caps are made to cover pipe ends of various forms and serve as a protective measure. End Cap Pipe Fittings are mostly used to waterproof the connections.

 

They are employed to seal the extremities of hydraulic or pneumatic pipelines and tubes. They are utilized in the machinery, processing equipment, and plumbing systems for home, commercial, and industrial water supply lines. They are installed on water pump lines with the express objective of eliminating air obstructions.
