Frequently Asked Questions

Common questions about Thermoline® Copper Tubes.

What is the difference between ASTM B280 and BS EN 1057? +

ASTM B280 is the American standard for Air Conditioning & Refrigeration (ACR). These pipes are cleaned, dehydrated, and capped to handle high-pressure refrigerants like R410A.

BS EN 1057 (formerly BS 2871) is the British/European standard for Water & Gas (Sanitary). These are typically used for plumbing, hot water systems, and gas distribution.

Are Thermoline® pipes compatible with R410A and R32 gas? +

Yes. All our ASTM B280 (ACR) copper tubes are seamless and designed with a high working pressure to safely handle modern refrigerants like R410A, R32, and R22. Please refer to our "Operating Pressure Guide" table for specific limits based on temperature.

Do you have ready stock for bulk project orders? +

Yes. Our Balakong warehouse stocks over 500 sizes of pancake coils and straight pipes. For large project requirements (VRV/VRF systems), we can arrange immediate lorry delivery within Klang Valley and standard courier options for other states in Malaysia.

How do I download the full specification catalogue? +

You can download the PDF catalog in the "Downloads" section above. It contains detailed data on Safe Working Pressure (SWP), bursting pressure, and weight per meter for all sizes.
