The standard procedure for this test is to flare the end of the pipe to a diameter 1.2 times the outside diameter.
HYDROSTATIC/PNEUMATIC PRESSURE TEST:
As per ASTM-A450 & 530 Standards, 100% Hydrostatic is carried out on all pipes & tubes using Hydraulic & pneumatic system.
EDDY CURRENT TEST:
This Test is Carried out on the entire length of tubes as per ASTM E-426 to determine the sub surface in homogenities. The Test is carried out on demand only.
On demand, We can also provide the Radiography testing through the Approved Inspection Agencies.
This test is only conducted only when specifically requested
There are no cracks on the welded section or on the base metal.
REVERSE FLATTENING TEST:
There are no cracks or blow holes can be observed on the welded section.
This test is conducted to check the strength of the welded section by subjecting, it to extreme compression stress. If the test piece with stands the specified compression stress without cracking, it is determined to be acceptable.
Each length of finished pipe is subjected to the hydrostatic or pneumatic pressure test. Each pipe must withstand the pressure without leakage.
