HSn70-1B Brass Tube For Corrosive Liquids In High Strength And
Corrosion Resistant Condenser
1. Description
The chemical element boron is added into hsn70-1b brass pipe, which
has special physical and chemical properties. It is mainly used in
condensing pipe series. The characteristic of hsn70-1b brass pipe
is that under the condition of water quality in power plant,
smooth, uniform, firm and dense protective film can be formed on
the inner surface of copper pipe. In the long-term use of fresh
water, it is not easy to scale, which is conducive to increase the
thermal conductivity and service life of copper tube.
Our company's brass tube grades mainly include HAi77-2,HSn70-1,
HSn70-1B, HSn70-1AB, H68A copper tube, fin tube and U-tube. The
products are produced in strict accordance with the standard, and
the finished products can be tested by the third party according to
the customer's requirements. These copper tubes are mainly used in
power plants, desalination, petrochemical, mechanical ships and
automotive heat exchangers. We have rich production experience,
professional technology, excellent equipment, superior quality,
reasonable price, high-quality service, so that our products sell
well all over the world, well received by customers.
