LINE STOPPING & BY-PASS SERVICE |
SERVICE DESCRIPTION |
|
Line stopping is a method that temporarily stops the pipe flow in a section of the pipe so as to allow for alteration and addition works to be carried out at the downstream of the pipeline; without stopping or purging the system.
By-pass service is a procedure that utilizes two line stop machines that will stop the pipe flow in a section of the pipe, while re-routing or divert the pipe flow through a by-pass section so that alteration works can be carried out while the system is in operation. |
PROBLEMS FACED IN ALTERATION WORKS |
TYPICAL APPLICATIONS OF LINE STOPPING |
|
Line Stopping is used in the following applications: · Alteration works to downstream of line stop location · Preparing the pipeline for bypass operation · Installing double line stops and a bypass for valve insertion · Installing double line stops and bypass for permanent relocation |

|
We are capable of providing line stopping service for the following applications: · Line stopping of pipeline diameter up to 24” · Line stopping of pipeline operating pressure up to 2,000 psig · Line stopping of pipeline temperature up to 300°C · Line stopping of pipeline containing oil, gas, water, steam or wastewater |
TYPICAL APPLICATIONS OF BY-PASS |
|
By-Pass is used in the following applications: · Alteration works to a pipe section without interruption to flow in system · Temporary or permanent bypass relocation |
