Line Stopping Machine & By-pass
Line Stopping Machine & By-pass (Low Pressure)
An equipment set that isolates a section of low pressure pipeline without shutdown and, with a by-pass, keeps supply running while the section is worked on.
Specifications
- Stopping size
- 80A 이하 (신형) / 500A 이하 (대구경)
- By-pass sets
- 50A · 80A · 100A · 200A · 300A
- Assembly
- Stopping unit + sandwich valve + stopping housing + by-pass hose

Key points
Double block with by-pass
Two stopping points isolate the section while a by-pass carries the flow around it, so supply never stops.
Field-assembled
Designed to be assembled and dismantled in stages, even in a tight excavation.
Verified sealing
Pressure is checked after isolation and a leak test is performed before hand-over.
