China wholesale Exhaust Joints Pipes – Exhaust Flexible Interlock Hose – Xinjing

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 guaranties the structural integrity of the welds holding the piece together.
