| 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. nestles in Dashagou Village, Jiangcun Township, Dingxiang County, Xinzhou, a place fondly dubbed the “hometown of Chinese forging.” With a registered capital of 5 million yuan, our strategic location is merely 100 kilometers from Taiyuan, the provincial capital, ensuring swift and seamless road and railway connectivity. The region's abundant coal, electricity, and iron resources empower us to be a leading manufacturer specializing in forged flanges and pressure vessel forgings. Our comprehensive capabilities encompass design integration, raw material procurement, cutting, forging, heat treatment, precision machining, mechanical and non-destructive testing, typing, painting, and meticulous packaging and shipping operations. Boasting an annual production capacity exceeding 10,000 tons, we cater to specifications from DN15 to DN6000mm. Each finished product can weigh up to 20 tons, with pressure ratings spanning 150 to 2500 pounds. Our diverse offerings adhere to national, American, British, German, Japanese, and custom standards for flanges and forgings.
Our production processes are underscored by the use of premium materials, including high-quality carbon structural steel, low-alloy high-strength steel, heat-resistant steel, and an array of stainless steel varieties such as carbon body, austenitic, martensitic, dispersion hardening, and duplex stainless steel.
