Our stainless steel seamless pipes and tubes are manufactured without a welded longitudinal seam, providing a continuous metal structure for demanding industrial applications in oil, gas, petrochemical, and power industries.

Our product range covers common austenitic grades such as 304, 304L, 316, 316L, 316Ti and 321, as well as duplex stainless steels including 2205, 2507 and 2304, and high-alloy grades such as 904L and 317L.

Available specifications:

• Outer diameter: 6-800mm
• Wall thickness: 0.1-100mm
• Length: up to 12,000mm or customized
• Standards: ASTM A213, A269, A312, A789, A790
• Surface finishes: BA, 2B, 2D, No.4, HL, and polished 4K/6K/8K

Industrial piping systems operate under high pressure, elevated temperatures, corrosive media, and continuous service conditions. Ordinary materials often fail to provide sufficient resistance to corrosion, oxidation, or mechanical stress.

Our seamless stainless steel pipe range provides comprehensive solutions:

• 304 and 304L - Practical combination of corrosion resistance and formability
• 316 and 316L - Enhanced corrosion resistance for demanding environments
• Duplex 2205 and 2507 - Higher strength and superior corrosion resistance
• 904L and 317L - Specialized grades for highly corrosive applications

• Oil & Gas Industry - Processing, transportation, and equipment systems
• Petrochemical Plants - Heat exchangers, process piping, chemical processing equipment
• Chemical Processing - Corrosion-resistant environments requiring specialized alloys
• Power Generation - Power plants, heat-transfer systems, boilers
• Industrial Construction - Projects requiring corrosion resistance and long-term durability

1. Select the Correct Stainless Steel Grade

• 304/304L - General-purpose corrosion resistance
• 316/316L - Enhanced corrosion resistance, particularly in chloride environments
• 2205 - Duplex stainless steel for high strength and corrosion resistance
• 2507 - Super duplex for demanding corrosion and strength requirements

2. Confirm Applicable Standard

• ASTM A269 - General corrosion-resisting and temperature service
• ASTM A213 - Boiler, superheater and heat-exchanger tubes
• ASTM A312 - General corrosive and high-temperature service
• ASTM A789/A790 - Ferritic/austenitic stainless steel applications

What is the difference between seamless and welded stainless steel pipe?

Seamless pipe is manufactured from a solid billet without a longitudinal weld seam, while welded pipe is formed from stainless steel strip and joined along the seam. The appropriate type depends on pressure, temperature, and application requirements.

What sizes of seamless stainless steel pipe are available?

Our range covers approximately 6-800mm outside diameter, with wall thicknesses from 0.1-100mm and lengths up to 12,000mm. Customized dimensions are available.

Can you provide customized processing?

Yes, we offer cutting, bending, welding, decoiling, punching, and moulding services according to customer requirements, along with customized lengths and packaging.
