| 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 resides in the heart of Dashagou Village, Jiangcun Township, Dingxiang County, Xinzhou, a place celebrated as the 'hometown of Chinese forging.' With a robust registered capital of 5 million yuan, our strategic location places us just 100 kilometers from the provincial capital Taiyuan, offering unparalleled access to rapid and convenient road and railway networks. Abundant in coal, electricity, and iron resources, we specialize in crafting premium forged flanges and pressure vessel forgings. Our comprehensive capabilities encompass everything from design and raw material procurement to cutting, forging, heat treatment, machining, and testing. We handle each step with precision, including non-destructive testing, mechanical typing, painting, packaging, and shipping. With an impressive annual production capability exceeding 10,000 tons, we offer specifications ranging from DN15 to DN6000mm. Our products, weighing up to 20 tons each, withstand pressures ranging from 150 to 2500 pounds, and meet a broad array of standards, including national, American, British, German, and Japanese, as well as custom non-standard flanges and forgings.
