Frequently Asked Questions

Most frequent questions and answers

A threaded cap is a type of pipe fitting used to seal the end of a threaded pipe. It features internal threads that match the external threads of the pipe, allowing it to be screwed on securely. Threaded caps are used to close off pipes temporarily or permanently, preventing fluid or gas from escaping and protecting the pipe from contamination or damage.

Threaded caps are available in a range of sizes to match different pipe diameters. Standard sizes generally range from 1/8 inch to 4 inches. Custom sizes can also be manufactured to meet specific needs and requirements.

Threaded caps are installed by screwing them onto the end of a threaded pipe. A suitable thread sealant or tape is often applied to ensure a leak-proof connection. The cap is then tightened using a wrench to create a secure seal. Proper alignment and fit are crucial to ensure effectiveness and prevent leaks.

Yes, we offer custom manufacturing solutions for threaded caps to meet specific requirements. Please contact us with your detailed specifications, and we will work with you to produce the caps tailored to your needs.

The lead time for threaded caps depends on the complexity and volume of the order. After reviewing your specifications, we will provide an estimated lead time. We are committed to delivering all projects on schedule while maintaining the highest quality standards.

Regular inspection of threaded caps involves checking for leaks and ensuring that the cap remains securely in place. It is important to inspect for any signs of corrosion or damage that might affect the seal or the integrity of the pipe system.

Threaded caps are typically made from materials such as carbon steel, stainless steel, brass, and other metals. The choice of material depends on the specific requirements of the application, including the type of fluid or gas, temperature, pressure, and environmental conditions.

Threaded caps are used in various industries, including oil and gas, petrochemical, plumbing, water treatment, and construction. They are essential for closing off pipe ends, performing maintenance, conducting pressure tests, and protecting pipes from damage and contamination.

Threaded caps are manufactured to comply with various industry standards, such as ASME B16.11, MSS SP-79, and ASTM standards. These standards specify the dimensions, tolerances, and material requirements to ensure reliability and compatibility in piping systems.

Threaded caps offer several advantages, including:

Easy installation and removal: Can be easily screwed on and off using a wrench.
Strong, leak-proof connections: Ideal for high-pressure and high-temperature applications.
Protection: Shields the end of the pipe from contamination and damage.
High strength and durability: Made from robust materials to withstand harsh conditions.
Compliance with standards: Ensures quality and reliability in piping systems.

Yes, threaded caps can be used for both liquid and gas applications, provided they are made from appropriate materials and installed correctly to handle the specific conditions of the system, including pressure and temperature.
