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.
Package

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.
