|
| |
In-Line Weld Test Tools are commonly used during the maintenance and modification of piping or process equipment, enabling hydrostatic pressure testing. Inserted into the piping or equipment component to be tested, In-Line Weld Test Tools provide a fast and efficient method of verifying the integrity of butt welds, joints or other welded pipe components. In-Line Weld Test Tools feature double block and bleed isolation, once set in position these tools provide a verified vapour barrier allowing hot work activities to take place safely onsite. |

Operator Benefits: |
| • |
Reduces system down-time and increases worksite safety
by minimising
pressure-test volume. |
| • |
Operators save time and reduce costs by limiting test area
to only the new weld or welded component. |
| • |
Timely completion of maintenance & modification activities. |
| • |
No requirement to flood & de-water gas systems. |
| • |
No requirement for full system pressurisation beneficial to
‘mature’ systems by decreasing potential for spading / leakage. |
| • |
Installed and activated in a matter of minutes. |
| • |
Sale or rental options available, complete with full ancillary
equipment. |
| • |
Fully certified client training provided by highly trained STATS
personnel to support Weld Test Tool hire. |

Key Features: |
| • |
Simple, straight forward installation and operation. |
| • |
Installed and activated in a matter of minutes. |
| • |
Large section high quality elastomer seals ensure a leak tight
seal, even in pitted pipework. |
| • |

internal obstructions such as weld beads, ovality, etc. |
| • |
Easily installed pre-hot work operations to provide a verified
double block and bleed vapour barrier. |
| • |
Suitable for use with most test mediums (liquid or gas). |
| • |

expansion and relaxation properties, even after many
operating cycles. |
| • |
Robust construction ensures years of trouble free operation
even in the harshest environments. |
| • |
Suitable for installation in horizontal, vertical and inclined
piping. |
