Huanghua Baihengda Xiangtong Machinery Manufacturing Co., Ltd. Was established in 2002. In order to meet the needs of sustainable development, further expand production scale, and enrich product categories, Hebei Hongrui Xiangtong Heavy Industry Co., Ltd. Was officially established in 2021, marking a new chapter in the company's development. The company's factory covers an area of 460, 000 square meters, with over 170, 000 square meters already built and put into use. Currently, the company employs 385 staff members, including 48 professional and technical personnel, specifically 6 senior engineers, 18 intermediate engineers, and 10 assistant engineers. With total assets amounting to 1.1 billion RMB, the enterprise boasts robust manufacturing capabilities and independent research and development strengths. The company specializes in the field of industrial equipment manufacturing, offering over 100 product types. Its main products include various pressure vessels such as mixing tanks, heat exchangers, towers, separators, etc., as well as storage and transportation equipment such as cryogenic tanks, tank trucks, and tank containers. The low-temperature storage tank adopts a vertical/horizontal double-layer structure, with the interlayer filled with vacuum powder insulation and subjected to vacuum pumping treatment. The inner and outer cylinders are connected by stainless steel slings, supplemented by fiberglass support members for positioning, resulting in a stable structure, compact layout, and low medium evaporation rate. All functional valves of the storage tank are centrally arranged at one end of the head, and the pipeline outlets are designed integratively, facilitating convenient operation and control. Standard pressure gauges and level meters are provided, and users can opt for a differential pressure transmitter for intuitive and convenient data monitoring. The storage tank is equipped with an integrated vacuum valve assembly (including a vacuum gauge tube), which enables high-precision vacuum measurement, effectively delays the aging of the insulation layer, extends the service life of the storage tank, and comprehensively improves the operational performance and safety of the equipment.
