Line Stop Machines

Line Stop Machines :- Overview

The line stop plugging machine is designed to isolate a pipe section by temporarily blocking the flow in a pipeline by isolating a section of pipe on-stream without shutdown while diverting the product flow using a bypass installed around an isolated section.

Line Stop Machines: Major Components

A Hydraulic Cylinder: Hydraulic cylinder is the driving force of the Line Stop Machine, enabling precise and controlled movement during the line-stopping process. It delivers the necessary pressure to position the plugging head accurately within the pipeline.
A Plugging Head Housing: Plugging head housing securely holds the plugging head in place. Its durable design allows it to withstand high pressures and temperatures, making it a vital component in pipeline isolation.
A Isolation Head: The isolation head plays a pivotal role in creating a secure seal within the pipeline. It acts as a barrier, isolating the flow of liquids or gases in the targeted section.
A Sealing Element: The sealing element is a critical component that provides a leak-proof seal between the isolation head and the pipeline. Made from high-quality materials, it ensures a tight fit and prevents leakage during the line-stopping process.

Hydraulic Cylinder

A single Hydraulic Cylinder can be used with several sizes of pipeline as per the following list:

Sr. No.	Model	Travel Length		Plugging Size		MAOP	Temp
Sr. No.	Model	Inch	Mm	Inch	Mm	PSI	°F
1	CM-0406	48	1220	4" - 6"	100 - 150	900	180
2	CM-0612	72	1829	6” - 12”	150 – 300	900	180
3	CM-1420	102	2590	14” - 20”	355 – 500	900	180
4	CM-2234	140	3556	22” - 34”	558 – 860	900	180
5	CM-3648	140	3556	36” - 48”	900 - 1220	900	180
