China wholesale Flexible tubing with flange Manufacturer - Exhaust flexible pipe with inner braid – Xinjing

NINGBO CONNECT AUTO PARTS CO., LTD is a brother company of Xinjing. Here is a manufacturing plant producing exhaust flex pipes (Someone call as exhaust flexible pipe, car flex, karflex, flexible tubes, flexible metal hose, stainless steel flexible exhaust pipe, etc.)  for road vehicles. Running with the quality system of IATF16949, Connect currently exports to over 30 countries worldwide, offering long-term partnership solutions to customers seeking reliability and high-quality products for the aftermarket &OE market.

Our exhaust flexible pipes products are in gas-tight, double-walled and streamlined design, suitable for designing and manufacturing exhaust systems, as well as for repair of defective exhaust systems.

The exhaust flexible pipe with inner braid is also called as universal flex pipe or double braided flexible exhaust pipe. It is ideal for naturally aspirated engines and provides laminar flow while retaining flexibility in the flex pipe itself. The inner braided liner protects the bellows from premature failure and is also ideal for eliminating exhaust “whistle”.

Features

This type of exhaust flexible pipe with inner braid is one of the most popular type flexible pipes.

The inner and outer two layers braids to our standard bellows provide all the features of standard bellows plus enhanced external protection, prevent hose elongation under pressure, and damp vibration. Our wire braid from our reliable supplier is manufactured from bright, high-quality annealed wire in a wide range of alloys and designs. Wire braid offers excellent coverage and minimizes spring-back during bellows fabrication.

The internal sleeve allows a pipe-to-pipe connection that reduces or eliminates stress between the two pipe ends.

• 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.
• Made of high temperature resistant & highly corrosion resistant material
• Available in all standard sizes & of any stainless steel material
• Compensate for the misalignment of exhaust pipes.

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.
