Flange plate | It is usually circular, and its diameter is determined according to the size of the connected pipeline. There are several bolt holes evenly distributed on it, which are used to install bolts to achieve a firm connection. | Selection of raw materials | Materials such as carbon steel, stainless steel, and alloy steel are often selected. The material selection must strictly comply with relevant standards and design requirements to ensure the quality and service life of the flange. | Pressure grade | Commonly, there are pressure grades such as PN0.25MPa, PN0.6MPa, PN1.0MPa, PN1.6MPa, PN2.5MPa, PN4.0MPa and so on. |
Sealing surface | Common types include flat face (FF), raised face (RF), etc. The flat sealing surface has a simple structure and is easy to process, but its sealing performance is relatively weak. It is suitable for working conditions with low pressure and non - toxic and harmless media. The raised face sealing surface has a boss added on the basis of the flat face, so it has better sealing performance and is suitable for medium - and low - pressure working conditions. | Forging or casting | The main methods for manufacturing the blank are forging and casting. Forging can improve the mechanical properties of the material, making the flange have better strength and toughness, but the cost is relatively high. Casting has high production efficiency and low cost, but the internal quality of the product is relatively poor. | Dimension specification | It is determined according to the nominal diameter (DN) and nominal pressure (PN) of the pipeline. The national standards have clear regulations on its dimensions, the number and diameter of bolt holes, the thickness of the flange, etc. |
Welding groove | The welding end is usually designed with a welding groove. Common forms include V-shaped, U-shaped, etc. The form and size of the groove vary according to different welding methods and pipeline materials, with the aim of ensuring the welding quality | Machining | After the blank is forged or cast, it is necessary to carry out machining operations such as turning, milling, and drilling to meet the specified dimensional and precision requirements. During the processing, the technological parameters should be strictly controlled to ensure dimensional accuracy and surface quality. | Sealing performance | Its quality depends on factors such as the form of the sealing surface, the material of the gasket, and the installation quality. Good sealing performance can prevent the leakage of the medium and ensure the safe operation of the pipeline system. |
Dingxiang Jinyu Forging Co., Ltd. proudly stands in the illustrious Dashagou Village, Jiangcun Township, Dingxiang County, Xinzhou—known across the nation as the "hometown of Chinese forging." With an impressive registered capital of 5 million yuan, our strategic location is just 100 kilometers away from the provincial capital, Taiyuan, offering the convenience of seamless and swift road and railway transportation. Nestled in an area rich in coal, electricity, and iron resources, we are a renowned specialist in the manufacture of forged flanges and pressure vessel forgings. Our comprehensive capabilities span the entire production process: from design and raw material procurement, to cutting, forging, heat treatment, machining, and rigorous mechanical and non-destructive testing. We ensure excellence in mechanical typing, painting, packaging, and shipping operations. With a robust annual production capacity exceeding 10,000 tons, we boast specifications ranging from DN15 to a remarkable DN6000mm. Each finished product can weigh up to 20 tons, with pressure capacities ranging from 150 to 2500 pounds, meeting national, American, British, German, Japanese, and custom non-standard flange and forging requirements.
Our production process is enriched by the use of superior materials, including top-grade carbon structural steel, low-alloy high-strength steel, heat-resistant steel, and a diverse array of stainless steels, such as carbon body, austenite, martensite, dispersion hardening, and duplex stainless steel. This ensures our products not only meet but exceed expectations for durability and performance.
Spanning over 10,000 square meters, our company employs a dedicated team of 105, including 8 highly educated management personnel.
