Double joint high quality brass fitting is suitable for the mechanical, chemical industry, pneumatic, air compressor, etc.Copper tube wall won't produce green and it is safe for drinking water.In order to improve the performance of some on the brass, brass in a yuan to join other alloying elements on the basis of brass called special brass. Commonly used alloying elements have silicon, aluminum, tin, lead, manganese, iron and nickel, etc.In adding aluminum brass may improve the yield strength and corrosion resistance of brass, slightly lower plasticity.In adding aluminum brass may improve the yield strength and corrosion resistance of brass, slightly lower plasticity.
Because of lead brass with excellent hot and cold processing properties and machinability, combined with good mechanical and physical performance, price, cheap, and is widely used in instruments and meters, electronics, electrical appliances, daily hardware, system for drinking water, etc, among them with dosage biggest Hpb59-1.
Water system components, however, lead in electronics, electrical appliances, and other waste to enter the water or soil, when after intake will produce harm to human body.
So the United States, Japan, the European Union and countries are restricted and puts forward the corresponding provisions, namely to July 1, 2006, electrical and electronic products exported to the countries and regions and plumbing, hardware equipment shall meet the requirements of lead. advantages1,durable in use
2, long service time
3,copper pipe and pipe fittings connection strong compaction
4,bacterial virus harmful objects cannot wear through it
5,corrosion resistance, resistance to high pressure
1,The brass material for national standard:T2,TP2;American-Standard ASTM:C11000,C12200;British standard BS:C102,C106etc.
2,The port diameter tube¢roundness tolerance +0.13mm -0.10mm
3, Bend angle 90°,Tolerance±1.2°
4, End of pipe plane error±1.0°
