After days of processing, the production of shell-and-tube heat exchanger repurchased by Saudi customers is getting to the end, and has passed the hydrostatic test and inspection by all parties. Shell-and-tube heat exchanger is mainly used in petroleum, chemical and other industries for medium heat exchange, which is one of the indispensable key equipment in the whole process.
In recent years, the most problems found in the supervision of heat exchanger products and the most difficult to rectify are the quality problems of tube head, and even the repair problems caused by unqualified tube head. Therefore, HC pays great attention in the manufacturing process. We select experienced senior welders for welding. The welding shall be carried out in strict accordance with the welding process. We not only strictly follow the welding process but also strengthen the process inspection at the same time.
The connection between the heat exchange tube and the tubesheet is the most important link in the whole heat exchanger manufacturing process. Although there are various factors, as long as we pay close attention to the process inspection in production and strictly implement the pre-welding, during welding and post-welding inspection procedures in accordance with the requirements, the quality can be ensured. In order to further improve the technical level of welders, we often organize skill training and learning, and require to work with certificates to avoid equipment quality problems caused by human factors.
It is the quality-oriented management of HC that enables more users to establish long-term cooperative relations with us. This order will once again deepen our contact with Saudi customers.
