ASTM B280 ACR Tubes WILKO ® KOREA

Copper Pipes and Tubings

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.

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.
Seamless structure facilitates maximum flow with minimum internal resistance.
Full length of 6 meters and each pipe is capped at both ends to ensure cleanliness during delivery. Also available in pancake coils of 15mtr per vacuum pack.
Storage – each pipe is permanently stored indoors, minimising oxidisation and ensuring cleanliness prior to sale.
Resistant to ultra-violet exposure. Pipes will not degrade as a result of exposure to sunlight.
Non-flammable and impervious. Environmentally friendly.
