ASTM B75 Tubes WILKO ® KOREA
Specifications
- ASTM B75
Applications
- WILKO ASTM B75 Tubes are standard Specification for Seamless Copper Tube for general engineering applications. They may be either round, square, or rectangular in profiles
- 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 ASTM B75 Tubes are made of top quality material and tested to ensure optimum performance
- 6mtr Hard Drawn Straight
- 6mtr Soft Annealed Straight
- 15mtr Soft Annealed Pancake Coil
Chemical Composition
- Alloy C12200 min 99.9% copper
- Phosphorus 0.015- 0.040% Mechanical Composition
Mechanical Composition
- 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.
- 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.
