Precision Slitting for Exhaust Pipe Producers

Your Tube Forming Machine Demands Perfect Edges

Flexible exhaust pipes and industrial flexible pipe connectors are manufactured from stainless steel or galvanized strips using spiral or folding methods on specialized tube forming machines.

The edge geometry and tolerance precision of the steel strip determines the quality of the pipe form. Irregular edges or tolerance deviations mean sealing problems, form inconsistency, and line stoppages.

CHY Steel provides precision slitting with material flexibility preserved and form-forming compatibility for automotive exhaust pipe manufacturers.

Flexible Exhaust Pipe Steel Strip - CHY Steel
The CHY Steel Advantage

In Exhaust Pipe Production, Tolerance is Critical

01
High-Temperature Materials

Stainless steel (304, 321, 409, 439) and aluminized-silicon (AS) coated steels meet the high-temperature requirements of exhaust systems. We stock all these materials and slit them to precise dimensions.

02
Formability Preservation

In flexible pipe production, the strip undergoes bending and folding. Slitting without surface hardening preserves material ductility and enables crack-free forming.

03
IATF 16949 Compatibility

We provide material traceability and test certificates supporting IATF 16949 quality system requirements for automotive tier suppliers. EN 10204 3.1 certificates available for every order.

FAQ

Frequently Asked Questions About Exhaust & Flexible Pipe

Common stainless steel grades for exhaust systems: SS 409 (most common, ferritic, low cost), SS 439 (better corrosion resistance, ferritic), SS 304 (austenitic, high corrosion resistance), and SS 321 (titanium-stabilized, high-temperature applications). Aluminized-silicon (AS) coated steel is also widely used for heat shield applications.

Flexible exhaust pipes are formed by bringing strip edges together in spiral or folding methods. Width tolerance deviation changes the overlap amount at the pipe seam. Too little overlap creates gas leakage risk; too much changes pipe diameter. Both scenarios exceed automotive OEM acceptance standards and disrupt serial production.

Yes. We provide EN 10204 3.1 format mill test reports for automotive and industrial applications, covering chemical composition, mechanical properties, and dimensional measurements. Simply share your requirements before ordering.

We accept both small batch and high-volume orders. We offer flexible order quantity options especially for project-based or prototype-stage automotive suppliers. We recommend filling in the quote form for minimum order quantities and pricing.
