Ensuring Excellence: The Comprehensive Tank Inspection Process at Glacier Tanks

The first step in our inspection process involves a meticulous visual examination of the tank's exterior. Our skilled inspectors check for any imperfections or damage, such as dents, scratches, and weld quality issues. This ensures that the tank not only looks pristine but also maintains its structural integrity.

Next, the tank's height, diameter, and port layout are measured against the engineering drawings. This step ensures that each tank meets the precise specifications required for its intended use. Any discrepancies are addressed immediately to maintain the highest level of accuracy.

During the dimensional accuracy check, we also verify that the port sizing matches the specifications on the engineering drawing. This makes certain that all ports are correctly sized and positioned for optimal functionality.

We fit CIP piping and other necessary fittings to the tank to ensure all parts connect as intended. This step is crucial for verifying that the tank will integrate seamlessly into the customer's system.

For jacketed tanks, each jacket is individually pressure tested at 35 PSI for 24 hours. Any failure or abnormality in the test data results in the tank being re-tested. All testing data is meticulously recorded and added to the tank's digital file, ensuring a complete history of the tank's quality control process.

After completing the exterior inspection and jacket pressure test, the tank is tipped onto a cradle. This position allows for easier access and rework, if necessary, during the interior inspection.

Our trained inspectors conduct a detailed examination of all weld seams, including those on ports, the manway, and the tank shell. This step ensures that all welds are of the highest quality and free from defects.

A thorough visual inspection is conducted inside the tank. Inspectors look for tool marks, weld splatter, pitting, and other imperfections, marking any areas that require further evaluation. A 200x magnification handheld digital microscope is used to photograph these issues for a detailed assessment.

Identified issues are evaluated by our shop personnel to determine if correction is needed. Any necessary rework and correction are completed promptly. A post-rework evaluation ensures that all issues have been resolved satisfactorily.

All tanks undergo a final pressure test at 35 PSI for 24 hours. As with the initial pressure test, any failure or abnormality results in re-testing. The testing data is recorded and added to the tank's digital file, ensuring a comprehensive record of the tank's quality control.

For tanks that do not require sealing, we perform a weight test. The dry weight of the vessel is recorded, followed by filling with water. After holding the water for at least 24 hours, the tank is emptied and weighed again. The weights are compared to ensure that the tank did not take on any additional weight, confirming its integrity.
