PRODUCT DETAILS
Pipe Cap
Pipe caps come in different shapes, including round, square, and oval, and can be designed for both threaded and welded connections. They ensure the integrity of piping systems during transportation, storage, and installation by protecting the pipe ends from dirt, debris, and environmental factors. Durable and easy to install, pipe caps are critical for maintaining system efficiency and safety.
Pipe Cap Product Introduction
Pipe caps, also known as heads, are fittings used to seal the ends of pipes, widely used in various industrial piping systems, particularly in petroleum, natural gas, thermal power, and nuclear power industries. Pipe caps are made from materials such as carbon steel, alloy steel, stainless steel, and low-temperature steel. Forming methods include die pressing. Pipe caps primarily adhere to international standards such as ASME B16.9-2018 and MSS SP-75-2019.
Pipe Cap Features
1.Excellent Sealing Performance: Ensures tight connection with pipes, preventing leakage of internal gases or liquids and blocking external dust, moisture, and impurities.
2.Good Protective Performance: Protects pipe ends from mechanical damage and corrosion, extending the service life of pipes.
3.Simple Structure: Typically hemispherical or elliptical in shape, easy to manufacture, and cost-effective.
