Premium Craftsmanship: Large HT-BLOC Welded Plate Heat Exchangers Delivered for a CNOOC Project

Shanghai Heat Transfer Equipment Co., Ltd. (SHPHE) recently 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 has a heat duty of up to 20 MW, a pressure rating of 3.0 MPa and a large heat transfer area. The project also set stringent requirements for 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, and the pressure tests were also passed on the first attempt. This demonstrates the company's technical expertise and manufacturing capability in high-end welded heat exchangers.

HT-BLOC is developed for demanding applications that require high heat transfer efficiency, a compact layout, corrosion resistance and reliable performance at high temperatures and pressures. It is well suited to 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 conditions, while the detachable end plates allow on-site mechanical cleaning of both flow channels, helping the equipment maintain optimal performance over the long term. Its compact design also allows more equipment to be installed in the same space, helping to reduce equipment investment and installation costs.

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