Hydrostatic test is a task of inspection point in the ITP, the hydrotest procedure should get approval code and all welding activities had been done inspection by all parties, NDT report to meet project requirement. Prepare the test package The following are 11 common steps to make a test package or prepare  a test package: Cover page See content of test package and download native file at the end of other topic, you may modify to meet your procedure. Content To reduce time for paperwork, you may input all common data into standard form such project name, client name, type of test, etc in the format standardization form or handwrite at site. Pre-test check list These task will be checked with your client before pressurization. Line list Spool number, line number or other identification should update in the line list for checking. Inspector will check all spools and then he will sign off in the drawing. The approved drawing should verify before make the test package. Line check To verif

Following the topic, we would like to share you the quality document for small skid. Inspection check list Procedures and inspection should prepare and included in your hand, NDE procedure, NDE map, welding map and NDE plan also prepared. You should make a content of procedures for control, type of inspection report, below is sample list of procedure. Document control Too many drawings/ document per each skid, so it should carefully update with latest revision, Line list should be updated and control the piping spool number, all spools to be identified in the test package later. Shop drawing, document submission to be documented revision number, date of submission, date of return, and approval code, etc.   Inspection report To control and monitor all inspection reports, the assigned coding number should generate before starting issue.   Welding summary For structural steel For piping   Material receiving inspection MRIR for piping, bolting, gasket, fitting MRIR for consumable MRIR for

  (IWE 1.08-1 - Figure 29: Welding voltage and welding current for different shielding gases) Above photo is an example to determine welding parameter with variant shielding gas. Example 1: 145A, 22V, 100% CO2 Example 2: 190A, 24V, 100% CO2 Example 1: 250A, 28V, 100% CO2 You are so referred to other shielding gas and variant welding parameter in IWE handbook -Module 1.08-1:2018 edition.

Welder assigned for this joint is a very important criteria. He have to be highly skilled as the NDT requirements for this joint is normally higher than that of other joints. My experience, the golden joints are subjected to RT, UT, MPI & hardness test. It depends on the standard being followed and the client requirements. Golden weld joint   is that joint in which the new piping is connected to the existing piping. Hence this joint cannot be hydrostatically tested. So it has to be ensured that it should be defect free as per the standard (eg: ASME B31.3 Section 345.2.3).
