Exhaust Flexible Pipes Unlined
NINGBO CONNECT AUTO PARTS CO., LTD is a brother company of Xinjing, a manufacturing plant producing exhaust flex pipes, exhaust bellows, corrugated pipes, flexible tubes and mounting components for road vehicles. Connect currently exports to over 30 countries worldwide, offering long-term partnership solutions to customers seeking reliability and high-quality flexible pipes products in the aftermarket &OE market.
Stainless steel exhaust flexible pipes in a gas-tight, double-walled and streamlined design suitable for design and manufacture of exhaust systems, as well as for repair of defective exhaust systems. The unlined exhaust flexible pipe is the most basic type without inner liner. It container a bellows with outer braids that allows a greater elasticity in terms of compression and elongation along the longitudinal axe.

Features
- Isolate vibration generated by the engine; thereby relieving stress on the exhaust system.
- Reduce premature cracking of manifolds and downpipes and help extend the life of other components.
- Applicable to different positions of the exhaust system, most effective when installed in front of the pipe section of the exhaust system.
- Double wall stainless steel for ensuring durability, technically gas-tight.
- Made of high temperature resistant & highly corrosion resistant material.
- Available in all standard sizes.
- Not recommended for turbocharged applications.
Quality Control
Every-single unit is tested at least twice through-out the manufacturing cycle
The first test is a visual inspection. The operator makes sure that:
- The part is placed in its fixture to ensure proper fitment on the vehicle.
- The welds are completed without any holes or gaps.
- The ends of the pipes are fished to the proper specifications.
The second test is a pressure test. The operator blocks all of the entrances and exits of the part and fills it with compressed air with a pressure equal to five times that of a standard exhaust system. This guarantees the structural integrity of the welds holding the piece together.
With over 10 years of experience, we will constantly enrich our technical and service skills, to win the trust of customers with our enthusiasm and sincerity, achieve win-win in cooperation and seek common development and growth with distinguished customers, suppliers and fellows.
