Could everyone tell me how to conduct pressure tests on a delayed coking tower to determine whether it has been manufactured properly?
**It is stipulated that before pressure vessels are put into use, strength tests (hydrostatic, pneumatic, hydrodynamic, etc.) must be conducted. Generally, this should be done by the equipment manufacturer prior to shipment, but it can also be carried out on-site. If you need to carry out the work on-site now, you must refer to the relevant regulations; this is a serious matter, and personnel from the labor department must also be involved.
Due to its special operating conditions, the design of coking towers is highly stringent, and the manufacturing requirements are very strict. Due to the large diameter of the tower, it is basically manufactured on-site. On-site production must be carried out strictly in accordance with the design requirements. The quality of coking tower fabrication is not determined solely by pressure tests; rather, it is controlled by adherence to standard fabrication procedures, a 100% qualification rate for weld inspections, and successful inspections before and after heat treatment. Conducting pressure tests on-site is mainly for leak detection.
