TESTING & INSPECTION

“100% Conformance to Customer Specifications” is the expectation of every customer. To ensure that this expectation is met, a combination of destructive and nondestructive tests are continually performed and monitored in accordance with our ISO 9001:2000 Quality System.

The primary nondestructive test used is 100% eddy current testing. The test unit is located in-line just after the tube is welded and prior to cutting the tube to length. This ensures that every inch of tubes is tested and avoids “end effects” associated with off-line eddy current testing.

Destructive tests, conducted in accordance with applicable ASTM or ASME specifications, include expansion testing, flattening, and reverse flattening testing. Overall tube integrity and weld integrity are critically evaluated with these tests. In addition, all tubes are visually and dimensionally inspected throughout the manufacturing process using a variety of gages including plug gages, ring gages, micrometers, calipers, and camber boards. Hydrostatic and pneumatic testing capabilities are also available.
