The biggest use of flanges is as a way to connect pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Reduced engineering costs.
Weld the flange and the pipeline evenly, and then fasten the connection with bolts to effectively connect the pipeline, valve, pump and other equipment accessories, so that the whole pipeline is integrated and starts to work normally.
It is the most widely used pipe fittings in the piping system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding, air conditioning and other departments.

Flange production process:
1) a: Forged flange
Saw billets of different specifications and models into flange blanks, add them to a reverberatory furnace and heat to 1000 degrees to take out, and then forge the flange blanks into ring flanges by forging machines such as forging presses and air hammers, b: steel plate flanges
Put the steel plate into the punching machine, put it into the corresponding mold, and directly punch it into a ring flange blank.
c: cast flange
Put the low carbon steel standard scrap into the intermediate frequency furnace and heat it to 1200-1500, pour it into the mold
The type is a ring flange blank.
2) The formed ring flange blank is processed into a ring flange on a CNC machine tool according to the drawing, and then the flange is drilled with a CNC drilling machine according to the drawing requirements, and the finished product is completed.
3) For the finished flange product, the thickness, hole diameter, center distance, inner and outer diameter of the flange shall be inspected according to the drawing requirements.
4) Type the flanges that have passed the inspection on the end face of the flange according to the customer's requirements, and do anti-rust treatment to the flange according to the customer's requirements, 1: paint, 2: anti-rust oil, 3: galvanized, and then install it. In wooden box for shipment.
The Central Plains Economic Zone is made! In the great historical practice of building the Central Plains Economic Zone, Zhengzhou City should build Zhengzhou Metropolitan Area into the core growth pole of the Central Plains Economic Zone. Then, how to realize the “industrial development of the city†in Zhengzhou’s strategic emerging industries, how to play an important supporting role in the construction of the Central Plains economic zone, please see the 18th Movement of the Central Plains Economic Zone, Zhengzhou, which was launched by this newspaper today. Strategic emerging industries have ignited the future of Zhengzhou. Solar energy makes your home's electricity meter slower by 281 degrees, 163 degrees, 135 degrees... On March 22nd, Ms. Wang, who lives in No. 116, Beihuan Road, Zhengzhou City, opened the electricity bill for three consecutive months and smiled. Since the use of solar energy-saving lamps, her home's electricity bill has been reduced month by month. Perhaps Ms. Wang never thought that in the new energy industry, the thin film solar cells and solid-state lighting projects in Zhengzhou High-tech Zone always walked in the forefront of Henan. At the end of August 2009, the first amorphous silicon thin film solar cell qualified product in the province was successfully launched in Argus in Zhengzhou High-tech Zone. In that year, the Henan Baolv Energy 500MW (MW) amorphous silicon thin film solar cell project with a total investment of 4 billion yuan was also started in the high-tech zone. During the 12th Five-Year Plan period, Zhengzhou's new energy industry development is based on Henan Baolv Energy Co., Ltd. and other enterprises, focusing on the development of the photovoltaic industry and accelerating the formation of an important solar film production base in the central and western regions." Yesterday, the Zhengzhou Municipal Government People said that Zhengzhou City will speed up the construction of Henan Baolv Energy Co., Ltd. 500MW amorphous silicon thin film solar cell project, Shengmao photoelectric solid-state lighting industrialization application demonstration base project, solar energy district Sunda energy company solar battery project, and strive to put Zhengzhou City has built an important new energy industry base in the central and western regions, and strives to achieve sales revenue of 50 billion yuan in the new energy industry. Diamond sees Zhengzhou's “superhard base†“Zhengzhou new material industry development, focusing on Huajing Company, Fu Nike Company and other enterprises, with the construction of superhard material industry cluster in Zhengzhou High-tech Zone as the carrier, focusing on the development of high quality. Diamond, nano-diamond, precision high-efficiency and super-hard material tools, and vigorously develop functional composite materials." Zhengzhou Industry and Trade Commission said that by 2015, we will strive to build Zhengzhou into an important super-hard material industry base in the country, and sales revenue of new materials industry. Strive to reach 50 billion yuan. The relevant personage of the committee also said that Zhengzhou City will vigorously promote the integration and development of the software industry and traditional industries, and support the Zhengzhou High-tech Zone to build a national-level innovative science and technology park, and promote the construction of the Central 863 Software Industry Park and the Wycombe Eco-Software Park. Strive to increase the sales revenue of the software industry by more than 30% annually in 2015, and build Zhengzhou into an important software industry base in the central and western regions of China. "Six-wheel drive" boosted the "Curved Road Overtaking" in the Central Plains Economic Zone . The Zhengzhou citizen Luo, who had a cold, knew that many prescription drugs prescribed by doctors were produced at the doorstep. The biomedical industry was playing a role. At the same time, the Health Guardian is constantly giving strength to the Central Plains Economic Zone and the Zhengzhou Metropolitan Area. "Bio-pharmaceutical industry, Zhengzhou High-tech Zone bio-pharmaceutical industry cluster and Xinzheng Pharmaceutical Industrial Park will be an important carrier." Zhengzhou Industrial and Information Committee told reporters that among them, Tailong Pharmaceutical, Tuoyang Bio, Huamei Bio, Antu Enterprises such as Green Branch, Banghe Biological, Tianjin Xinzheng Pharmaceutical, Zhengzhou Lingrui Pharmaceutical, and Henan Kangtai Pharmaceutical will become the “emphasis†of development. By 2015, we will strive to build Zhengzhou into a national-level biological and pharmaceutical industry base, and strive to exceed 50 billion yuan in sales revenue. In addition to strategic emerging industries such as new energy, new materials and biomedicine, the Internet of Things industry and the production service industry will also become strategic emerging industries in the future. Among them, by 2015, the Internet of Things industry is expected to make Zhengzhou Internet of Things. Technology and applications are at the forefront of the country, achieving sales revenue of 30 billion yuan; and the productive service industry, by 2015, is expected to achieve an average annual growth rate of more than 20%. “In the process of building the Central Plains Economic Zone, Zhengzhou City will be transformed into a 'core growth pole', among which strategic emerging industries will become 'locomotives.†Zhengzhou Industrial and Commercial Committee said that in the development of strategic emerging industries in Zhengzhou It will present new energy, new materials, bio-pharmaceuticals, Internet of Things, software industry, and production services. "Six-wheel drive", the added value of high-tech industry will reach 150 billion yuan, accounting for the city's industrial added value. The proportion will also reach about 37%, boosting the “Current Overtaking†in the Central Plains Economic Zone.
