Product Description
Brass tube is primarily used in water pipes, gas pipes, air conditioning pipes, refrigeration pipes and firefighting fields. It is with high strength, outstanding thermal conductivity even in low temperature conditions.
Brass pipes are sturdy and corrosion-resistant, making them the first choice for modern contractors in the installation of water pipes, heating and cooling pipes in all residential commercial buildings. The shiny surface of brass tube also makes it ideal for interior decoration, buildings, pubic art and musical instruments.
Our brass tube is available in nominal size from 1/4” to 3” (from 6.35mm to 76.2mm). The range of brass tube is available as hard temper, half hard temper and soft annealed temper. The brass tubes are manufactured according to ASTM B135, ASTM B111 standard.
