At CTR, we believe each qualified product comes from the correct design, correct materials and correct production processes, not from inspection alone. Because of that, we pay strict attention to raw materials and the production process. During the production process, we carry out inspection on individual pieces first, then inspect the process, and final piece inspection to ensure the products are qualified before going onto the next production stage.
We make sure the dimensions are accurate on all parts, as we know and understand that there is a problem in the dimensions and size out of tolerance, the pipe fittings are rendered useless. IN the competitive market, we pay strict attention to the finishing on the surface, including painting, marking and packing.
For welded fittings, we do RT, UT, PT, MT and critical tests such as bursting tests.
