European Standard: EN 10217-7, DIN 17456

Other certifications: ISO 9001, PED 2014/68/EU (Pressure Equipment Directive)
 

Production Process
Seamless Tube: Cold Rolled/Cold Drawn (High Precision), Hot Extruded (Large Diameter Thick Wall Tube)
Welded Pipe: TIG, PAW, laser welding (high precision)
Surface treatment: pickling, polishing (180#-600#), sandblasting, passivation (to enhance corrosion resistance)

Product Core Advantages
Excellent corrosion resistance
304/316 for acid and alkali environments, 316L resistant to chloride corrosion (seawater, chemical media)
Duplex steel (2205) is resistant to stress corrosion cracking, longer service life.
 High Strength & High Temperature Resistance
310S high temperature resistance (≤ 1100 ºC), suitable for boilers, heat exchangers
2205 duplex steel is 2 times stronger than 304 and lighter in weight.
Sanitary applications
Inner wall electrolytic polishing (Ra≤0.8μm), FDA/3A compliant, used in food, pharmaceuticals
Precision machining capability
Cold rolled precision tube tolerance ±0.05mm, suitable for semiconductor, hydraulic system
Environmentally friendly and recyclable
100% recyclable material, RoHS/REACH compliant.
