Countries Adopt ASME BPVC
Every Job Starts With the Code, Not the Torch.
Design review before a single cut is made.
Our certified engineers verify that design calculations, material mill certs, and welding procedures conform to the applicable ASME BPVC section before mobilisation. We cross-reference B31.3 Process Piping or B31.1 Power Piping for attached systems, confirm P-number groupings, and document every deviation on a formal NCR before it becomes a field problem.
12 Sections
ASME BPVC covers power boilers, materials, nuclear components, pressure vessels, NDE, and piping — every section in our library.
ASME Boiler & Pressure Vessel Code
Survey phase — P&ID and code cross-reference before material release.
Shop fabrication — GTAW root pass on a stainless nozzle, Section IX WPS on the bench.
Certified Processes. Documented at Every Joint.
SMAW, GMAW, GTAW, FCAW, SAW — qualified per Section IX.
Each weld is performed by a Section IX-qualified welder using a documented Welding Procedure Specification (WPS) and supported by a Procedure Qualification Record (PQR). Weld maps and heat logs maintain material traceability from plate to nameplate. Our QC manager performs visual inspection to Code requirements throughout — undercut, arc strikes, and geometry deviations are documented and resolved before the next pass.
U · S · R
Three ASME stamps authorising fabrication of pressure vessels (U), pressure piping (S), and repairs (R) to BPVC requirements.
ASME BPVC Certification Program
In-Situ Repair Without Compromising the Schedule.
Preheat controlled. PWHT executed. No shortcuts.
Field repairs on pressure-retaining equipment follow NBIC Part 3 and the applicable ASME section. Preheat is maintained by controlled temperature monitoring to P-number rules — thermocouple strips, not guesswork. Post-weld heat treatment is performed per BPVC schedule and verified by chart recorder. Every repair weld is visually inspected by the QC manager and logged as a nonconformance item until cleared.
4 hrs
Maximum field-response time from emergency call to boots on-site for shutdown support within our primary service territory.
Weld Field Operations SLA
Field repair — SMAW on a 10-inch process line, preheat verified by thermocouple.
NDE phase — radiographic film placement on a longitudinal seam weld.
Find Every Flaw Before the Fluid Does.
RT, UT, MT, PT — then 1.3× MAWP to prove it.
Radiographic testing reveals internal weld integrity; ultrasonic testing maps material thickness and sub-surface flaws; magnetic particle and dye penetrant testing clear surface defects on every weld and heat-affected zone. Once NDE is accepted, the vessel is subjected to hydrostatic test at 1.3 times the Maximum Allowable Working Pressure per UG-99, held, reduced to MAWP, and examined for leaks at all connections and joints.
1.3× MAWP
Minimum hydrostatic test pressure per UG-99 — every pressure-retaining item in the vessel is subjected to this proof load before release.

A Complete Paper Trail. Stamped and Signed.
ASME Data Reports, mill certs, weld maps — every page.
Certification handover includes the ASME Manufacturer's Data Report (U-1 or equivalent), material certificates confirming ASME-approved stock, all WPS/PQR documentation, the NDE report package, hydrostatic test chart, and any NCR disposition records. The ASME Certification Mark is applied to the nameplate only after an authorised ASME Inspector signs off. Your procurement team gets a package that closes any third-party audit.
100+ Countries
ASME BPVC is adopted internationally — your stamped vessel is accepted by regulators from Houston to Rotterdam.
