IP Joint

[Saurabh Jain]

Hello experts,

I would like to know what is IP joints in piping(31.3)?

In essence, an IP pipe joint is any connection made between pipes that are sized using the IPS or NPS standards, regardless of the specific connection method.

Are you sure? There is no such a term in 31.3

Greetings,

I think 'IP' joint means 'incomplete penetration'(partial penetration) joint.

Greetings,

In Saudi Aramco projects, the term "IP" refers to the Initial Production weld for piping joints. As per the requirements of SAEP-324 (Welder Performance Qualification Procedure), every welder must perform a minimum of three (3) Initial Production (IP) welds following the successful completion of their Welder Qualification Test (WQT).

This process ensures that welders not only meet qualification standards in a controlled test environment but also demonstrate their proficiency in actual site conditions before being released for production welding activities.  

Reference - SAEP-324

Best Regards

Dhana
