Threaded Pup Joint Usage Guide

The threaded pup joint is a connection accessory, usually used to connect two pipes or pipes and valves, and is characterized by a threaded connection method and a short length. Short length means that the threaded pup joint is shorter than conventional connection accessories, which can save space and cost.

How to match the threaded pup joint

When installing the threaded pup joint, a threaded joint is required to connect the pipe to ensure the stability and sealing of the pipe. The threaded pup joint can be used with threaded joints of various specifications, which can be internal thread joints or external thread joints, which are convenient for connecting with the external and internal threads of other pipes or valves.

Therefore, the threaded pup joint is an economical, practical, convenient and fast connection accessory. When purchasing the threaded pup joint, you need to pay attention to its thread diameter and connection method to ensure smooth connection with the threaded joint.

How to use the threaded pup joint correctly

1. Determine the use environment and material

Before using the threaded pup joint, you need to select the appropriate threaded pup joint model and material according to the use environment and the material of the required connected pipe. Generally speaking, threaded pup joints can be used to connect pipes of different materials, but attention should be paid to their corrosion resistance.

2. Check the appearance and internal threads of the threaded pup joints

Before use, check whether the appearance of the threaded pup joints is intact and whether the internal threads are intact. If damage or deformation is found, it should be replaced in time.

3. Make pipe connections

Align the threaded pup joints with the pipe to be connected, rotate the threaded pup joints counterclockwise, insert them into the pipe, and ensure that the threaded pup joints are completely fixed. At the same time, be careful not to over-tighten to avoid damaging the threads.

4. Perform a pressure test

After the connection is completed, a pressure test is required. The test pressure should be determined according to the actual use environment and pipe specifications. After the test, check whether the threaded pup joints have leakage.

Precautions for threaded pup joints

1. During the installation process, pay attention to the position and direction of the pipe to ensure smooth connection of the threaded pup joints.

2 In the process of tightening the threaded pup joints and threaded joints, tools need to be used to tighten them gradually instead of tightening them all at once.

3. After installation, the connection needs to be inspected to ensure the sealing of the connection.

How to choose a threaded pup joint

1. Choose the appropriate material according to the application and medium.

2. Choose a threaded pup joint that meets the standards according to the pressure of the pipeline and system.

3. Consider the connection method. You can choose internal thread, external thread or pipe insertion threaded pup joint according to your needs.

4. Pay attention to the outer diameter and length of the threaded pup joint to ensure that it meets the requirements after connection.

Summary

The above are the basic methods and precautions for using threaded pup joints. If used and maintained correctly, threaded pup joints can bring you a convenient and safe use experience.
