Product Overview

Our oval pipe and round to oval tube solutions are designed to connect different pipe profiles while providing a compact and efficient layout. It creates a smooth change from a circular inlet to an oval outlet, making it ideal for automotive exhaust systems, custom fabrication, industrial piping, and applications where installation space is limited. Our round to oval pipe is manufactured from stainless steel, carbon steel, and other metal materials, with customized dimensions, wall thicknesses, lengths, and surface finishes.
 
The  oval adapter can be produced according to specific inlet and outlet sizes, helping ensure accurate fitment and reliable connection in OEM and aftermarket projects. With precision metal forming and tube fabrication capabilities, we provide consistent dimensions, clean surfaces, and customized production from prototypes to volume orders.

Provides A Solution
To Your Problem

If you have any comments or suggestions or our quality or service can not satisfy you, please call our customer service center, register through our website, our customer service staff will be the first time to understand the situation, timely contact with you.

Do you support customization?


* Yes, we specialize in fully customized mandrel bending solutions to meet diverse automotive and industrial requirements.

* Our capabilities include custom angles, diameters, materials, and surface finishes for standard and non-standard tubes.

* With advanced CNC mandrel bending machines, precise forming control, and experienced engineers, we ensure defect-free, high-quality bends that meet ISO 9001 and IATF 16949 standards.

* Whether for exhaust systems, intake pipes, fuel lines, or custom assembly interfaces, we provide reliable solutions tailored to your exact specifications.

What information is required for a custom mandrel bend quotation?


For accurate quotation, we typically require drawings or samples, or tube diameter, wall thickness, bend angles, material specifications, surface finish requirements, and intended application. This helps us deliver precise custom tubing solutions.

How do you ensure product quality?


* We ensure product quality through controlled mandrel bending processes, strict welding standards, and comprehensive inspections.

* From raw material inspection to forming and welding, each step is monitored to maintain consistent dimensions and structural integrity.

* Advanced inspection equipment, including 3D scanners and coordinate measuring machines (CMM), is used to verify accuracy.

* Our quality management system complies with ISO 9001 and IATF 16949, ensuring reliable performance for tubing applications.

What materials can you process?


* We work with a wide range of materials, including stainless steel, carbon steel, aluminized steel, titanium, aluminum, and more.

* Our precision bending capability ensures stable forming and consistent quality, even for

demanding or non-standard material specifications.

Do you provide samples?


Yes, we can provide samples. Each sample undergoes dimensional and forming verification using 3D scanning and CMM inspection to confirm compliance with drawings, standards, and functional requirements before bulk production.
