Frequently Asked Questions

Most frequent questions and answers

A threaded elbow is a type of pipe fitting used to change the direction of a pipe or tubing by 45 or 90 degrees. It features internal threads that match the external threads of the pipes, allowing it to be screwed onto the pipe to create a change in direction. Threaded elbows are used to navigate around obstacles or to alter the flow path in a piping system.

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

Threaded elbows are installed by screwing them onto the ends of the pipes. A suitable thread sealant or tape is typically applied to ensure a leak-proof connection. The elbow is then tightened by hand or with a wrench to secure the connection. Proper alignment is crucial to ensure a tight and effective seal.

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

The lead time for threaded elbows 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.

Yes, threaded elbows 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.

Threaded elbows are commonly made from materials such as carbon steel, stainless steel, brass, and other alloys. The material selection depends on factors like the type of fluid or gas, temperature, pressure, and environmental conditions of the application.

Threaded elbows are used in various industries, including oil and gas, petrochemical, plumbing, water treatment, and construction. They are essential for changing the direction of pipe runs, allowing for flexibility in the layout of piping systems and facilitating the connection of pipes around obstacles.

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

Threaded elbows offer several advantages, including:

Ease of installation: Can be quickly threaded onto pipes without the need for welding.
Versatility: Suitable for creating directional changes in a piping system.
Strong, leak-proof connections: Ideal for high-pressure and high-temperature applications.
High strength and durability: Made from robust materials to withstand demanding conditions.
Compliance with standards: Ensures quality and reliability in piping systems.

Regular inspection of threaded elbows involves checking for leaks and ensuring that the elbow remains securely tightened. It is important to look for any signs of corrosion, wear, or damage that could affect the integrity of the piping system.
