304L seamless pipes are secured with multiple layers of steel or plastic-steel strapping at both ends and in the middle of the bundle. Protective material is inserted during bundling to prevent dents or scratches on the pipe surface. Open ends are sealed with plastic or metal caps. For high-quality pipes, woven bags, wooden boxes, or iron frames may be used for secondary protection.
All pipes are packaged and labeled in accordance with export and industry standards, ensuring clear labeling and secure bundling to meet safety requirements for long-distance transportation.

JN provides comprehensive quality control for 304L seamless pipes.
Raw materials are strictly controlled to meet ASTM A213/A312 standards. During the cold drawing or cold rolling process, dimensional tolerances, wall thickness, and surface finish are precisely controlled. During final inspection, nondestructive testing is used to identify internal defects in the pipes.
Water pressure or air tightness tests are also performed to verify pressure resistance.
Finally, mechanical testing and metallographic examinations confirm the mechanical properties and microstructure, fully guaranteeing the reliability and service life of the 304L seamless pipes.
Why Do Customers Choose JN 304 Seamless Pipe?
Compliant with ASTM A312 Standards
Our 304 seamless pipes are manufactured strictly in accordance with the American Society for Testing and Materials (ASTM) A312 standard. Our products, compliant with ASTM A312, offer reliable compressive strength, excellent weldability, and a proven track record, ensuring long-term, safe operation in pressure-transport systems for chemical, oil, and natural gas industries.
Excellent Corrosion Resistance
304 seamless pipes meet the demands of inland marine and coastal applications. For example, they can be used in freshwater systems within ships, some ventilation systems, or in pipelines in coastal plants that are not in direct contact with seawater.
High-Quality Products
304 seamless pipes offer a uniform, high-pressure-bearing capacity, a dense internal structure, and no potential risks associated with welds. They effectively resist media corrosion and operating pressure, ensuring long-term stable and safe operation of equipment.
Reasonable Pricing
As the most widely used austenitic steel grade, 304 stainless steel offers excellent mechanical properties and corrosion resistance while offering significant cost advantages over duplex steels. Larger orders for our 304 seamless pipes will result in more favorable pricing.
