hot tap fittings
PSI not only performs hot tap and line stop services but also sells hot tap and line stop fittings.
Type I and Type II hot tap fittings are available through PSI, each engineered and fabricated to give additional reinforcement to pipe sections to ensure their reliability and integrity. A variety of full encirclement and partial encirclement products are also available depending on the level of needed support and use.
All standard hot tap fittings are engineered to meet the requirements of ASME B31.3 and B31.4/8. Hot tap fittings are typically A234 Grade WPB or WPC with A105 flanges.
PSI can engineer other materials to meet pipeline material Requirements or customer requirements. PSI’s hot tap fittings are compatible with major models of hot tapping equipment and are compliant with most pipeline design codes.
Typical flanges are ASME Class 150, 300, or 600. We also custom-engineer other classes or flange types for our customers.
line stop fittings
If you need full port size-on branch connections, PSI offers connections for standard line stop operations in stock. If you have custom requirements, we will engineer and supply reduced branch sizes where needed.
In addition to the standard line stop fittings, PSI supplies fittings with guide bar plugs for utilization when future line pigging is anticipated.
