304L Seamless Stainless Steel Pipe for Food Processing

Yes, we are a direct manufacturer with two production facilities in China. One plant, located near Shanghai, focuses on stainless steel and aluminized tubes, while the other, in Shandong Province, specializes in mild steel and aluminized tubes.

We source our raw materials directly from leading steel mills in China to ensure stable quality and full traceability. Our main suppliers include: 1.Stainless Steel: TISCO 2.Aluminized Steel: VAMA (ArcelorMittal joint venture) 3.Mild Steel: Baosteel We can also supply 409AL tubes based on project requirements.

Yes. Our materials are supplied in accordance with the required chemical composition and mechanical property standards for each grade. For example: 1.AISI 304: produced in full compliance with the relevant chemical and mechanical requirements 2.AISI 409: compliant with required specifications, with tensile strength typically in the range of 360 to 380 MPa, depending on the material batch Material certificates can be provided upon request.

Our standard production does not include annealing, matte finishing, or internal seam pickling/flattening. However, we use laser welding technology, which results in a very small internal weld bead that generally does not interfere with further processing such as mandrel bending. If required, we can arrange outsourced services such as: 1.Annealing 2.Pickling 3.Other surface treatments These services are available at additional cost depending on the specification and order volume.

Yes, we can provide Level 3 PPAP documentation when required. Each part number can be supplied with its own complete PPAP package, including a duly signed PSW by an authorized representative.
