Stainless Steel Double Expansion Ring Local Repair

The Neicun stainless steel repair technology involves lining a thin-walled stainless steel pipe or sheet inside the pipe to be repaired, and then welding them together using the TIG welding process to form an integrated structure. This further enhances the original pipe's pressure resistance, leakage prevention, and corrosion resistance, thereby extending the pipe's service life. The lining pipe can have a certain gap with the original pipe, and filling material can be injected into the gap to bond the stainless steel lining pipe with the original pipe into a composite pipe with a unified structure.

Process Features:

In-situ pipeline repair at the original location, without full-line excavation, with a construction length of over 300 meters to enhance the original pipeline's pressure resistance.

Enhance the pipeline's corrosion resistance properties

Stainless steel pipes are resistant to high temperatures, non-toxic to water quality, and meet safety, hygiene, and health standards, as well as energy-saving and environmental protection pipe criteria.

The inner lining is smooth, resists scaling, reduces fluid friction, and enhances pipeline conveying capacity.

Pipe suitable for materials ranging from DN200 to DN3000
