Rule 19
Periodic Inspection and Pressure Testing of Pressure Vessels
Rule 19 assignments cover inspection and pressure testing of pressure vessels within the recognition scope, including LPG bullets, propane vessels, industrial-gas vessels, Horton spheres, mounded pressure vessels and underground pressure vessels. The exact inspection plan depends on vessel design, service history, accessibility, previous reports, licence conditions and the statutory requirements applicable to the installation.
Pacific Engineering coordinates the review of available vessel records and the field inspection or witnessing required for the assignment. Supporting examinations may include ultrasonic thickness measurements and other relevant NDT records where required by the approved scope or inspection plan.
- Hydrostatic or applicable pressure-test witnessing
- Horton sphere inspection and certification support
- Mounded vessel and underground vessel testing
- LPG storage vessel periodic inspection
- Review of NDT and thickness-measurement records
Rule 33
Certificate of Safety for Compressed-Gas Storage Installations
For organisations installing or operating compressed-gas storage systems, the Rule 33 service addresses the statutory safety assessment and certification of the installation within the authorised scope. Assignments may involve above-ground pressure vessels, LPG bullets, mounded storage vessels, underground vessels and Horton spheres together with their connected safety systems and installation documentation.
The purpose is not merely to inspect a vessel in isolation, but to examine the applicable installation details, available documents, safety arrangements and site conditions needed for the relevant Certificate of Safety.
- Compressed-gas storage safety inspection
- LPG bulk storage installation certification
- Horton sphere safety certificate support
- Mounded and underground vessel installations
- Documentation for PESO licence or renewal processes

Rule 13(2)
Inspector Services for Pressure Vessels Under Fabrication
As stated by the company, Pacific Engineering & Testing Services is authorised as an Inspector for issuance of a Certificate of Control for vessels under fabrication, including spheres, mounded vessels, underground vessels and cryogenic vessels. Fabrication-stage inspection is planned around the approved design, material records, welding and examination stages, pressure testing and final documentation applicable to the vessel.
Early coordination with the fabricator or EPC contractor helps identify witness points and documentation requirements before critical manufacturing stages are completed.
- Pressure vessel fabrication inspection
- Material and traceability-document review
- Welding and NDT record coordination
- Hydro-test or final-test witnessing
- Certificate of Control documentation
Technical Support
NDT Records, Documentation Review and Compliance Coordination
Pressure-vessel certification assignments often depend on reliable supporting evidence. Depending on the rule, asset and agreed scope, Pacific Engineering may review or witness relevant NDT activities, thickness readings, prior test reports, drawings, data sheets, repair records and other technical documents necessary to establish the inspection basis.
Where specialist testing is performed by an external laboratory or agency, the records can be coordinated as part of the wider statutory inspection assignment.
- Ultrasonic thickness measurement records
- MPI, DPT, UT or RT report review where applicable
- Previous certificate and licence-document review
- Vessel data-sheet and drawing verification
- Inspection planning and compliance coordination

Frequently asked
Practical answers before you schedule.
What is a Competent Person under the SMPV (U) Rules?
A Competent Person is recognised for defined functions under specified rules. Recognition is scope-specific; the correct competent person and rule must be matched to the inspection or certification required.
What is the difference between a Competent Person and an Inspector?
In broad terms, the competent-person functions listed here relate to testing and safety certification under Rules 18, 19, 33 and 43, while the stated Inspector authorisation under Rule 13(2) relates to control certification for vessels under fabrication.
How often must a pressure vessel or safety valve be tested?
The applicable interval depends on the vessel category, service, licence conditions, statutory provisions and any directions or amendments in force. Pacific Engineering reviews the documents and advises the scope before inspection; the website does not substitute for the governing rule or licence condition.
Which documents should we share with an enquiry?
Typically: vessel identification and capacity, gas/service, location, drawings or data sheet, current PESO licence details where applicable, previous certificates, repair history and the required rule or certificate.
Can you inspect Horton spheres, mounded and underground vessels?
The company’s stated authorisation includes these vessel categories under the relevant Rules 19 and 33 scope. Final acceptance depends on the current recognition document and the precise assignment.
Do you provide PESO pressure-vessel testing in Ghaziabad, Noida and Delhi NCR?
Pacific Engineering & Testing Services is based in Muradnagar, Ghaziabad and can assess inspection requirements in Delhi NCR and other locations. Mobilisation is confirmed after reviewing the vessel type, site location, applicable rule and inspection scope.
What information is required for an SRV or relief-valve testing quotation?
Share the number and type of valves, service or gas, set pressure, vessel or installation details, site location, previous test information and the required Rule 18 certification scope.
Can you support a new pressure vessel during fabrication?
The stated Inspector authorisation under Rule 13(2) covers Certificate of Control assignments for specified vessels under fabrication. Contact the team before fabrication advances so that drawings, materials, welding records, inspection stages and witness points can be reviewed.
Is NDT included in pressure-vessel testing?
NDT requirements depend on the vessel, rule, condition, service history and approved inspection plan. Relevant examinations and reports may form part of the supporting evidence, but the precise requirement is confirmed only after document and scope review.
