| 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 Dashagou Village, Jiangcun Township, Dingxiang County, Xinzhou, a region affectionately known as the 'hometown of Chinese forging.' With a registered capital of 5 million yuan, our company benefits from its prime location, just 100 kilometers from Taiyuan, the provincial capital, offering swift and convenient access to both road and railway transportation. Boasting rich resources in coal, electricity, and iron, we are a distinguished manufacturer specializing in forged flanges and pressure vessel forgings. Our comprehensive capabilities encompass the entire production chain, from design, raw material procurement, cutting, forging, heat treatment, and machining to mechanical testing, non-destructive testing, mechanical typing, painting, packaging, and shipping operations. We proudly achieve an annual production capacity exceeding 10,000 tons, with specifications ranging from DN15 to DN6000mm. Each finished product can weigh up to 20 tons, and our pressure capabilities span from 150 to 2500 pounds. Our offerings include national, American, British, German, Japanese, and non-standard flanges and forgings.
Our production relies on a diverse array of materials, including premium carbon structural steel, low-alloy high-strength steel, heat-resistant steel, and a variety of stainless steels (such as carbon body, austenitic, martensitic, precipitation hardening, and duplex stainless steel).
Spanning over 10,000 square meters, our company houses 105 dedicated employees, including 8 management personnel with a high school education or higher.
