Dynamic Flexible Pipe
Showarasen
Dynamic flexible tubes are a type of distribution pipe designed to navigate and circumvent the obstacles posed by certain installation sites. Their flexibility additionally makes them capable of absorbing soil settlement and seismic activity.
Roadside excavations are fraught with complexities compounded by the fact that these sites often uncover electricity and gas services. Such situations call for a piping solution that can both navigate on-site obstacles, and tolerate soil displacement.
Dynamic flexible tubes, despite their smallest diameter starting from 80A, are soft and flexible enough to be bent by hand. This product effectively removes the need for complicated, cumbersome assemblies that utilize pre-shaped elbows. The result is an installation method that greatly eases the hardship of working in cramped and complicated environments.
SRS’ bellows are made from one of two materials (depending on configuration): SUS316L or SUS304. The flexible tube’s triple-layered structure consists of expandable bellows, a stainless blade designed for protection, and an anti-corrosive taping.
The connection points of each tube are configured to our customers’ specifications. If necessary, these components can be specially insulated.
