Pipe cap

Pipe caps (also called pipe caps or pipe plugging caps) are a type of sealing device in a pipeline system, mainly used for closing the end of a pipeline or temporarily plugging it. It can effectively seal the pipeline opening, prevent external pollutants from entering the interior of the pipeline, and prevent leakage of media in the pipeline. Pipe caps are widely used in industries such as petroleum, natural gas, chemicals, electric power, and metallurgy, and are often used in pipeline construction, maintenance, pressure testing, storage, and transportation. Pipe caps are usually designed to be closed and can be installed by welding, flange connection, threaded connection, etc. to ensure the tightness of the pipeline system after closure. The shape of the pipe cap can be round, spherical, elliptical, etc. The specific shape and size are customized according to the pipeline specifications and usage requirements.

Pressure test, dimensional accuracy test and corrosion resistance test will be carried out before leaving the factory to ensure that it meets customer requirements.

 

5. Packaging and transportation:

Packaging: According to the size and quantity of the pipe caps, protective packaging methods such as wooden boxes, pallets, bubble films, etc. are usually used to ensure that the products are not damaged during transportation.

Transportation: We provide a variety of transportation methods such as sea transportation, air transportation, and land transportation to ensure on-time delivery according to customer needs.

 

6. Precautions:

Inspect before installation: Before installing the pipe cap, check whether the pipe interface is clean and ensure that the installation surface is flat to avoid affecting the sealing effect.

Installation requirements: When installing the pipe cap, ensure that it is firmly connected to the pipeline, and the bolts or welding should be tightened in place to avoid sealing failure due to looseness.

Pressure range: Select a pipe cap suitable for the pressure level according to the use pressure of the pipeline to avoid safety hazards caused by exceeding the use range.

Regular inspection: During use, regularly check the connection between the pipe cap and the pipeline to ensure sealing and stability and prevent leakage.
