11 steps to prepare a hydrotest package

🧪 Hydrostatic Test Package Preparation Guide

Inspection Point in ITP – QA/QC Controlled Document

🔧 General Requirements

Hydrostatic testing is an essential inspection activity listed in the Inspection and Test Plan (ITP). Before performing a hydrotest, the following conditions must be fulfilled:

The hydrotest procedure has been approved by the client and/or consultant.
All welding activities within the test boundary must be completed and inspected by all parties.
Non-Destructive Testing (NDT) must be performed according to the project specification, with acceptable results.
All relevant documentation must be collected for inclusion in the test package.

📦 11 Steps to Prepare a Hydrotest Package

1. Cover Page

Include project name, client, contractor, system name, line class, and test type.
A sample form can be customized to suit your project format.

2. Content Sheet

Provides a summary index of documents included.
Pre-fill standard information (e.g., project name, test type) in templates to save time.
Forms may be typed or handwritten at the site, depending on project practice.

3. Pre-Test Checklist

Conduct this jointly with the client before pressurization.
Items include valve positions, flange bolt checks, blinds installed, supports in place, etc.

4. Line List

Include spool numbers, line numbers, service description, test pressure, and length.
Inspector must check and sign each spool on the drawing.
Use only approved drawings to prepare the test list.

5. Line Check

Verify all piping spools are installed per the approved drawings.
Mark or highlight test spools on isometric drawings and P&IDs.
Confirm valve direction, check valve orientation, and isolate components not to be tested.
Submit flagged drawings for client verification and signature.

6. Welding Data

Include welding summary logs (WPS/PQR/WPQ) and NDT reports (RT, MT, PT, etc.).
All visual and dimensional inspections should be satisfactory before pressure testing.

7. Material Traceability

Ensure all materials and spools are traceable.
Maintain MTCs and spool traceability records as part of the QA requirement.

8. Pressure Test Certificate

Record actual test pressure, date/time, duration, and hold period.
Use calibrated pressure gauges (within 6 months).
Install two gauges: one at the highest point and one at a visible point for monitoring.
Gauge range must be 1.5 to 4.0 times the test pressure per applicable code.

9. Pressure Chart Recorder (if required)

Attach the pressure chart to the package for test record verification.
Record should reflect start/hold/end time and pressure trend.

10. Temperature Record (Optional)

Record ambient temperature or water temperature during testing.
Useful for justifying pressure drops due to temperature changes.

11. Punch List

Include any outstanding work or comments found during pre-test or testing.
If no issues are found, create a "no comment" punch list endorsed by the client.

📤 Test Package Submission

Submit the complete hydrotest dossier to the client or third party for review and approval. The typical contents include:

✅ Cover page
✅ Hydrotest instruction or method statement
✅ Pre-test checklist / Line check record
✅ Line list
✅ Marked P&ID and Isometric drawings (highlight test area)
✅ Material traceability records
✅ Welding summary and NDT reports
✅ Pressure test certificate
✅ Calibration certificates (pressure gauge, chart recorder, thermometer, etc.)
✅ Photos of gauge reading at start/end of test (if required)
✅ Final punch list (with or without comments)

💡 All documents should be scanned and compiled into a single PDF file for submission.

Skid fabrication - inspection documents for QC

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 structural steel
MRIR for electric & instrument
Material traceability

Visual inspection

For piping
For structure

Dimensional inspection

Base frame - structure.
Piping spool, loose items.
Tie-in point report.

NDE Reports

MT/PT reports
RT/UT reports
Hardness test, ferrite test (if any)

Coating inspection report

Blasting and painting inspection report
Pickling and passivation report

Factory acceptance test

Tie-in point report.

Bolt tightening report.

Leak test for instrument air.

Leak test for pipe system.

Function test for valve, equipment.

Packing report

Important do not miss during inspection: to check all the packing list, listed out all items installed or mounting on skids, spare part items, loose items, location of packing items, protection, preservation, etc.

Record all packing and photos evident should be kept.

To make sure all package had been checked and verified by all parties, and signed off in the packing list before moving next stage of the issue "IRN - Inspection Release Note".

Inspection release note

The IRN will be issued by Client or their representative inspector will issue it because the inspection point is Hold Point.

This is an evident document for payment and confirmation that had been inspection before shipping.

Final Manufacturer data book

Collect all procedure, instruction used for fabrication and inspection record to the final MDR.
MDR Index / content will be confirmed with Client before making.
Construction drawings will be made an as-built for reviewing and approval.
All outstanding work list should close out or update in the master list for further actions.
Guide to make a sample MDR.

Storage and submission

Retention of document shall follow your quality system, such 3 years or 5 years.
Document submit eight hard copy or soft copy or both to your client.
Do not submit via email with many files attached in the email, it should combine into a “.ZIP” folder, not compressed “.RAR” file.
