| 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. is proudly situated in Dashagou Village, Jiangcun Township, Dingxiang County, Xinzhou, a region renowned as the 'hometown of Chinese forging'. With an impressive registered capital of 5 million yuan, our company is strategically positioned just 100 kilometers from the provincial capital, Taiyuan, offering easy access to convenient and rapid road and railway networks. Abundant in natural resources like coal, electricity, and iron, we stand as a leading authority in the professional manufacturing of forged flanges and pressure vessel forgings. Our robust capabilities encompass the full spectrum of services, from design and raw material procurement to cutting, forging, heat treatment, machining, mechanical testing, non-destructive testing, and mechanical typing. We also offer painting, packaging, and shipping operations. Boasting an annual production capacity exceeding 10,000 tons, we cater to an extensive range of specifications from DN15 to DN6000mm. Our finished products can weigh as much as 20 tons per unit, with pressure specifications ranging from 150 to 2500 pounds. Our expansive portfolio includes national, American, British, German, and Japanese standards, alongside bespoke non-standard flanges and forgings.
Our production utilizes only premium materials, including high-quality carbon structural steel, low-alloy high-strength steel, and heat-resistant steel. We also work with a broad range of stainless steels, encompassing varieties like carbon body, austenite, martensite, dispersion hardening, and duplex stainless steel, ensuring top-tier quality in every product we manufacture.
Spanning over 10,000 square meters, our company is staffed with 105 dedicated employees, among whom 8 are experienced management personnel holding high school education or higher. Our organizational structure is detailed in the attached chart. Our facilities include specialized workshops for cutting, forging, machining, and packaging.
