ASTM B280 ACR Tubes WILKO ® KOREA

Specifications

  • ASTM B280

Applications

  • WILKO ASTM B280 Tubes are Standard Specification for Seamless Copper Airconditioning & Refrigeration Tubes (ACR). Tubes come mainly designated as Type L.
  • These pipes are manufactured using pure copper deoxidized with phosphorus, leaving relatively high residual phosphorus content. They are mostly available in hard drawn temper but ALL tubes are pre-cleaned with Nitrogen and capped to maintain internal cleanliness under normal conditions of handling and storage.
  • Product under this specification can be furnished in either O60 (soft annealed) or H58 (drawn general purpose) temper. Coils are normally in O60 temper and straight lengths in H58 temper.
  • Very popular in Commercial, Residential and Industrial ACR applications.
  • WILKO ASTM B280 ACR Tubes are made of top quality material and tested to ensure optimum performance.

Application

  • Standard copper tubes of type L are used for residential and commercial uses.
  • Some specific uses include interior above ground plumbing, domestic water, service and distribution, fire protection, solar, fuel and oil, HVAC, compressed air, LPG gas, snow melting and vacuum systems.
  • Copper tubes of type L can be used with sweat, compression and flare fittings.
  • Alloy C12200 min 99.9% copper
  • Phosphorus 0.015- 0.040%
  • Melting Point: 1083oC (1981oF)
  • Thermal Expansion: 0.117mm/10oC.m (0.00118inch/10oF)
  • Modulus of Elasticity: 2.46 x 106 psi (17000MPa)
  • WILKO copper pipe is manufactured using only the highest grade phosphorus deoxidized copper (DHP) complying with UNS 12200.
  • Combined with modern extrusion technology, the seamless pipes are produced in KOREA to meet stringent demands in plumbing, air conditioning and refrigeration applications.
  • Engineered to the exact specifications exceeding even the highest standards of performance, WILKO copper pipes offer superior products ideal for commercial, industrial and domestic usage.
  • WILKO copper pipes are of the highest quality and manufactured to the strictest standards.
  • Positive material identification (PMI) test conducted on every WILKO import.
