Brass Pipe have strong, corrosion resistant properties, and become a modern contractor in all
of commodity house pipes,heating, cooling water piping installation of choice.Widely used for
air-conditioning and refrigeration field service,heat exchange use,connecting tubes,distribution,
fire protection,solar,natural gas,liquefied petroleum gas,vent piping.
Nondestructive Testing
1.Unless nondestructive testing has been waived,Brass tubesshall be subjected to a nondestructive test.T
he manufacturer shall select the nondestructive test that is most suitable for the tube size and the application
2.Eddy-current testing is the standard nondestructivetest,andall tubes of appropriate size shall be eddy-current
tested in accordance with A
3.Tubes that are not of a size suitable for eddy-current test capabilites shall be tested by the hydrostatic test as
described in B ,or by the pneumatic test as described in C
A:Eddy Current Test-Each tube up to 3 8/1 in 【79mm】 in outside diameter shall be subjected to an eddy-current test..
B:Hydrostatic Test -When specified , the tube shall sand,without showing evidence of leakage an internal hydrostatic
pressure to subject the material to a fiber stress of 7000 psi [48MPa],determined by the following equation for thin hollow
cylinders under tension p=2Stl(D-0.8t)
C:Pneumatic Test- – -When specified, the tube shall be subjected to an internal air pressure of 60 psig [400 kPa] minimum
for 5 s without showing evidence of leakage. The test method used shall provide for easy visual detection of any leakage,
such as by immersion of the tube under water or by the pressure differential method. Any evidence of leakage shall be cause
for rejection.

Application | The copper tubes are made of pure electrolysis copper. They are precise in size and smooth on surface. Besides,they are of good heat conductibility. Thus, they are widely used for heat exchangers, radiators, coolers, electro-heat-up pipe, Air conditioner and refrigerators. The straight pipes can be used for oil transportation, brake pipes, water pipes and gas pipes for construction. | |||
Πακέτο | Export standard package: bundled wooden box or be required; The packing will reach the standard of export. Or as the customers’ request. In addition, We will make the products with good surface protection. |
