Copper Pipes and Tubings

JISH 3300 C1220 WILKO ® KOREA

Specifications

  • JISH 3300 C1220

Applications

  • WILKO JISH 3300 C1220 Tubes follow Japanese Industrial Standard extending to all copper and copper alloy seamless pipes and tubes having round section.
  • These pipes are manufactured using pure copper deoxidized with phosphorus, leaving relatively high residual phosphorus content. They are readily available in both hard drawn or soft annealed temper.
  • Coils are normally in soft annealed temper while straight lengths in hard drawn temper.
  • Very versatile specification with wide ranging applications spanning across various industries.
  • WILKO JISH 3300 C1220 Tubes are made of top quality material and tested to ensure optimum performance.
