Recently, Shanghai Heat Transfer Equipment Co., Ltd. completed and shipped a batch of large HT-BLOC welded plate heat exchangers custom-designed and manufactured for a CNOOC project.

Designed for demanding operating conditions, each unit features a heat duty of up to 20 MW, a pressure rating of 3.0 MPa, and a large heat transfer area. The project also placed stringent requirements on plate forming, core assembly accuracy, and welding quality. During manufacturing, SHPHE maintained strict quality control, achieving a 100% first-pass acceptance rate in welding inspection, while the pressure tests also passed on the first attempt. This fully demonstrates the company’s technical expertise and manufacturing capability in high-end welded heat exchangers.

HT-BLOC is developed for demanding applications requiring high heat transfer efficiency, compact layout, corrosion resistance, and reliable performance under high-temperature and high-pressure conditions. It is well suited for reboiling, condensing, and liquid-liquid heat transfer duties in the petroleum, petrochemical, natural gas, chemical, and refining industries.

Its fully welded core ensures safe, efficient, and reliable operation under harsh working conditions, while the detachable end plates allow on-site physical cleaning of both flow channels, helping the equipment maintain optimal performance over the long term. In addition, its compact design enables more equipment to be installed within the same space, helping reduce equipment investment and installation costs.

With years of expertise in the heat exchange equipment industry, SHPHE has developed mature and reliable HT-BLOC technologies and manufacturing solutions. We will continue to provide high-quality products and professional solutions for customers in China and around the world.
