Product Introduction

304L Stainless Steel Pipe is a low-carbon austenitic stainless steel pipe with excellent corrosion resistance, weldability and machinability, suitable for conveying corrosive media and welded structure applications.

Product Features

The low-carbon formula combines 18% Cr and 8% Ni; effectively resisting corrosion from moisture, chemical media, and the atmosphere, extending service life.

Easy to cut, bend, flare, and weld; meeting the manufacturing needs of complex piping and equipment.

Acid-washed, polished, and mirror-finished surfaces are available; meeting industrial and sanitary application requirements.

Manufacturing Process

Raw Material Control
High-quality 304L stainless steel is selected, and its chemical composition and mechanical properties are rigorously tested.

Manufacturing
Cold rolling, cold drawing, or automatic welding processes are employed to ensure uniform microstructure and stable performance.

Dimensioning
Dimensional tolerances are controlled through sizing, straightening, and cutting processes.

Surface Treatment
Acid pickling, passivation, polishing, and mirror finishing are supported to improve corrosion resistance and appearance quality.

Quality Inspection
Dimensional, composition, mechanical property, hydrostatic, and non-destructive testing are conducted to ensure products meet international standards.

FAQ

Q: What is the difference between 304L and 304 stainless steel pipe?

A: 304L has a lower carbon content (≤0.03%), resulting in a lower risk of intergranular corrosion after welding, making it more suitable for welded structures, chemical equipment, and corrosive environments.

Q: What standards can you provide for 304L Stainless Steel Pipe?

A: We can produce according to international standards such as ASTM A312, ASTM A269, ASTM A213, ASME SA312, and EN 10216-5, and support customized standards.

Q: Can you provide seamless and welded pipes?

A: Yes. We can provide 304L seamless pipes and 304L welded pipes to meet the needs of different pressure ratings and applications.

Q: What sizes and specifications do you offer?

A: Outer diameter, wall thickness, and length can all be customized. We have ample stock of standard sizes and can also produce according to drawings or project requirements.

Q: What tests are performed on the products before they leave the factory?

A: Each batch of products undergoes chemical composition testing, dimensional inspection, mechanical property testing, hydrostatic testing, and non-destructive testing to ensure compliance with relevant standards.

Q: Can you provide material certificates?

A: Yes. We can provide EN 10204 3.1 Material Test Certificate (MTC), quality inspection reports, and third-party testing reports.

Q: What surface treatment options are available?

A: We offer pickling, passivation, polishing, brushing, and mirror finishes to meet industrial and sanitary application requirements.

Q: What media are suitable for 304L stainless steel pipes?

A: Suitable for water, steam, food media, weak acid and weak alkali solutions, and most industrial fluid transportation environments.

Q: Do you support OEM and customized production?

A: Yes. We can customize sizes, lengths, surface treatments, packaging methods, and product markings according to customer requirements.

Q: What is your minimum order quantity (MOQ)?

A: MOQ can be negotiated according to specifications and order requirements, and supports full container load (FCL), less than container load (LCL), and bulk project procurement.
