[Cangzhou China Railway Steelmaking Plant] explosion-proof pipeline expansion joint product introduction

Introduction of Cangzhou China Railway Equipment Manufacturing Materials Co., Ltd.

Cangzhou China Railway Equipment Manufacturing Materials Co., Ltd. is a Sino-foreign joint venture, which was registered and established in Cangzhou Bohai New Area in December 2006. The project is the first large-scale project to enter the Bohai New Area. The project covers an area of 13,000 mu, of which the first phase covers an area of more than 6,000 mu, with a total investment of more than 20 billion yuan. The overall design of the project has a high starting point and advanced environmental protection facilities. It is a large-scale comprehensive iron and steel complex integrating coking, coal chemical industry, sintering, ironmaking, steelmaking, steel rolling, oxygen production, waste heat and waste gas power generation, and sewage treatment. The project has been fully completed and reached production capacity, with an annual output of more than 6 million tons of iron, steel, and timber, 2.2 million tons of CDQ coke, and 200,000 tons of methanol, with an annual sales income of more than 20 billion yuan and employment of more than 10,000 people. The equipment level ranks first among private steel enterprises in the country, and the scale ranks first among private steel enterprises in Hebei.

Main equipment: 4 6m 55-hole CDQ, 3 240m2 sintering machines, 2 10m2 shaft furnaces, 6 lime kilns, 3 2500m3 blast furnaces, 3 180t converters (supporting LF and RH refining furnaces), 1250mm, 1780mm new alloy material rolling production line each; supporting the construction of chain grate rotary kiln, waste heat and waste gas power plant and sewage treatment plant.

Leading products: 1.5-20mm (thickness) × 450-1630mm (width) high-quality carbon structural strip steel and low-alloy high-strength strip steel, which can be directly used for the production of large-diameter longitudinally welded pipes and spiral welded pipes, high-speed guardrails with a diameter of 140-508mm Plates, steel formwork and other steel structures such as automobile girders and shelves can also be used as cold-rolled strip steel substrates. Thin-walled welded pipes, cable trays, barrels and cans, stamping parts and other industries.

3. Railway Steelmaking Plant Project Related FAQ

Q：The pipeline expansion joint used on the steel-making vibration platform of the steel mill has a vibration frequency of 120~140Hz and an amplitude of 6 ~7mm, can you buy it?

A：The Above photos are the site of the lined pipeline expansion joint used on the vibration platform of Cangzhou China Railway Continuous Casting:

Q: How much pressure is there?

A: The customer said 1.2-1.3MPa, the main pressure is 1.2-1.3MPa, the pressure on the soft joint is not so large, because there is no pressure gauge installed in this place, so the specific pressure is not clear.

Q: What Rubber Material？ EPDM rubber?

Answer: Natural rubber lined with steel wire.

Q: What is the temperature?

A: There is steam in normal use, and the temperature is about 70 degrees. People can’t get in. The temperature of the main inlet water is about 70 degrees. When it comes to the soft connection, the water temperature is generally between 35 degrees and 42 degrees. The environment around the pipeline expansion joint The temperature is about 70 degrees, because there is a high temperature source around, resulting in evaporation of water vapor, the actual temperature inside the pipeline expansion joint is about 35-45.

Q: What is the vibration frequency?

A: The vibration frequency is 120-140, and the amplitude is 6-7mm.
