MESCO Stainless Steel Pipe






Detail Information
Stainless Steel Tube
· MESCO is a supplier to many globally renowned automotive enterprises, providing stainless steel perforated tubes for use as mufflers.
· It has extremely rich experience in the production of stainless steel tubes, and can deliver goods within 30 days for conventional sizes.
· It strictly controls the quality and will arrange the shipment only after inspection.
The base materials and weld seam of the tube undergo the solid solution treatment integrally. Exhaust steel tubes are produced in accordance with the APQP process. The outer diameter tolerance and inner weld residual height are strictly controlled to ensure no internal weld traps exist. Each piece is subjected to a 100% one-by-one pressure detection at 15 kg pressure for 15 seconds. The entire length of the pipe measures 12 meters with throw light on both inside and outside surfaces, followed by an 18-meter tube pressure test.
