In-Service Welding: Ensuring Safety and Precision Under Pressure
In-Service Weldingis specialized welding on a piping system that is flowing and/or under pressure.
“Thermal Analysis” is carried out to mitigate the risk involved by calculating a) HAZ hardness value b) Cooling Rate c) Pipe Inside Temperature. These values are used to control the risk of burn-through and in determining a suitable Welding parameters / Procedure for In-Service Welding.
Our Standard Welding Package :
- Thermal Analysis model program
- Welding Procedure Specifications (WPS) per API 1104 Appendix B, ASME Sec. IX, AS 2885.2 – 2007
- Complete Non-Destructive Examination (NDE) procedure
- Quality Assurance Plan
- Comprehensive equipment and tooling package with state-of-the-art pre-heating and monitoring
- Trained welders qualified according to API 1104, ASME IX recommendations
- We develop special Weld Procedure to avoid the need for Post Weld Heat Treatment (PWHT) especially arises per the wall thickness restrictions of ASME B 31.3 code, including Finite Element Analysis (FEA) and Engineering Critical Assessment (ECA) if required.
Thermal Analysis
PMI Service
The most critical variable for determining the crack susceptibility during and after welding is the chemistry of the material. The percentages of Carbon (C), Manganese (Mn), Chromium (Cr), Molybdenum (Mo), Vanadium (V), Nickel (Ni), and Copper (Cu) are used to calculate the Carbon Equivalent (CE), value of a material.
It is considered to be best practice to determine the actual CE value of a pipeline to confirm the applicability of existing welding procedures or to develop new welding procedures. We provide PMI services (at site) for the pipeline where Carbon Equivalent not available, we use portable spectrograph equipment and / or metal shaving equipment to analyse the CE value of a pipe.
