| 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. |
Nestled in the picturesque Dashagou Village of Jiangcun Township, Dingxiang County, Xinzhou, Dingxiang Jinyu Forging Co., Ltd. stands proudly as a beacon in the renowned 'hometown of Chinese forging.' With an impressive registered capital of 5 million yuan, our company boasts an enviable position just 100 kilometers from the provincial capital, Taiyuan, offering seamless access to road and railway networks. Blessed with abundant coal, electricity, and iron resources, we expertly craft forged flanges and pressure vessel forgings with precision and care. Our comprehensive capabilities encompass design, raw material procurement, cutting, forging, heat treatment, machining, mechanical and non-destructive testing, mechanical typing, painting, packaging, and shipping. Our robust annual production exceeds 10,000 tons, with specifications stretching from DN15 to DN6000mm. Impressively, each finished product can weigh up to 20 tons, and withstand pressures from 150 to 2500 pounds. We cater to a variety of standards including national, American, British, German, Japanese, as well as bespoke non-standard flanges and forgings.
Our production thrives on the utilization of premium materials such as high-quality carbon structural steel, low-alloy high-strength steel, and heat-resistant steel. We also employ an array of stainless steel types including carbon body, austenite, martensite, dispersion hardening, and duplex stainless steel, ensuring exceptional performance and durability.
