Under pressure operations
PMC provide a range of activities which can be utilised under pressure.
We offer a complete flowstopping service for planned and emergency operations on a full range of diameters and materials across all pressure ranges (LDN, LTS, NTS).
These include steel, cast and ductile iron and PE systems at all pressure ranges up to 100 Bar on pipelines up to 48” diameter.
We utilise various stopple techniques such as:
• PE squeeze off;
• IRIS stop;
• Bag off technology;
• Fixed head stopple;
• Bifurcated stopple;
• Bond and Bolt.
We also undertake under-pressure drilling for all diameter and material limits up to 100 Bar and 48” diameter.
