Stamped parts are manufactured through stamping with minimal material consumption. They are lightweight, have good rigidity, and after plastic deformation of the sheet metal, the internal structure of the metal is improved, resulting in an increase in the strength of the stamped parts.
⑵ Stamped parts have high uniformity in size with the same module and good interchangeability. It can meet general assembly and usage requirements without further mechanical processing.
During the stamping process, stamped parts have good surface quality and a smooth and beautiful appearance because the surface of the material is not damaged. This provides convenient conditions for surface painting, electroplating, phosphating, and other surface treatments.
In the continuous production of modern industry, flanges are inevitably affected by factors such as medium corrosion, erosion, temperature, pressure, and vibration, resulting in leakage problems. Due to errors in the processing dimensions of the sealing surface, aging of the sealing components, and improper installation and fastening, flange leakage is easily caused

Sliding flange: Sliding flanges have a lower hub because the pipeline enters the single flange before welding. This provides sufficient strength for both the internal and external welding to prevent leakage. Sliding flanges are designed to match slightly larger outer diameter pipes. They are superior to neck flange welding, as the initial cost is lower for many users, but the installation cost is unlikely to be low later because there are fewer added neck flanges.

Overlapping flange: Overlapping flanges are actually the same sliding flange, unless it is within a radius between the hole and the flange race. This is a necessary radius with a flange to accommodate the end of the overlapping stub. Usually, overlapping flanges and overlapping stubs are mated together at the end of the month to assemble the system.

The socket welding flange is a similar sliding flange, unless it has a hole and a reverse hole size. Match the counter hole with the pipeline to insert the pipeline into a sliding flange similar to a flange. Matching pipes with the same ID and diameter in smaller holes. The limitation is the built-in hole, which serves as a specialized shoulder sleeve for pipes to stay at the bottom. This eliminates any flow restrictions when using socket welding flanges.

The company specializes in producing various standard models of flange materials. Flanges are disc-shaped parts that are commonly used in pipeline engineering, and are used in pairs. In pipeline engineering, flanges are mainly used for connecting pipelines. Install a flange plate on the pipeline that needs to be connected. For low-pressure pipelines, threaded flanges can be used, and for pressures above 4 kilograms, welded flanges can be used. Add sealing points between the two flanges and tighten them with bolts. Flanges with different pressures have different thicknesses and use different bolts. Flange, also known as flange or flange It is a component that connects pipes to each other. Connected to the pipe end. There are holes on the flange that can be threaded with bolts to tightly connect the two flanges. Seal the flanges with gaskets. Flange fittings refer to fittings with flanges

⑴. Reasonable mold design. In the progressive die, the arrangement of cutting sequence may affect the accuracy of stamping part forming. For the cutting of small parts of stamped parts, a larger area of punching cutting is usually arranged first, followed by a smaller area of punching cutting to reduce the impact of punching force on the forming of stamped parts.
⑵. Press down on the material. Overcoming the traditional mold design structure, a material gap is opened on the discharge plate (i.e. when the mold is closed, the material can be compressed). For key forming parts, the discharge plate must be made into an embedded structure to facilitate the solution of grinding (pressure) damage caused by long-term stamping at the pressing part of the discharge plate, which cannot compress the material.
⑶. Add strong pressure function. Thicken the size of the unloading insert pressing part (normal unloading insert thickness H+0.03mm) to increase the pressure on the material on the concave die side, thereby suppressing the flipping and twisting deformation of the stamped part during punching.
⑷. Trim a sloping or curved surface at the end of the convex die blade. This is an effective method to reduce punching force. Reducing the buffer cutting force can alleviate the tensile force on the material on the concave die side, thereby achieving the effect of suppressing the flipping and twisting of stamped parts.
⑸. In daily mold production, attention should be paid to maintaining the sharpness of the cutting edges of the convex and concave molds. When the cutting edge wears out, the tensile stress on the material will increase, leading to an increased tendency for the stamped part to flip and twist.
⑹. Unreasonable or uneven punching gaps are also reasons for the flipping and twisting of stamped parts, which need to be overcome.

Liaocheng, our company's products are produced according to national standards, with strict quality control. With strong technical strength and excellent production experience, our factoryLearn management and complete the production of dozens of large-scale projects both internally and externally

However, the main design disadvantage of flat welding flanges is that they cannot guarantee no leakage. This is its design deficiency: the connection is dynamic, and cyclic loads such as thermal expansion and fluctuations can cause movement between flange faces, affecting the function of the flange and damaging its integrity, ultimately leading to leakage. No product can be without defects, it's just about trying to minimize the shortcomings of the product. Therefore, when producing flat welding flanges, the company strives to maximize the performance of the product and maximize its effectiveness.
　　
　　

The main components of flange blanks are:
Steel with a carbon mass fraction of less than 2.11% and without intentionally added alloying elements. Sometimes also referred to as plain carbon steel or carbon steel. Carbon steel, also known as carbon steel, refers to iron carbon alloys with a carbon content Wc of less than 2.11%. Carbon steel generally contains small amounts of silicon, manganese, sulfur, and phosphorus in addition to carbon.
(1) Carbon steel can be divided into three categories based on its use: carbon structural steel, carbon tool steel, and easy cutting structural steel. Carbon structural steel is further divided into two types: engineering construction steel and machine manufacturing structural steel;
(2) According to the smelting method, it can be divided into open hearth steel and converter steel;
(3) According to the deoxidation method, it can be divided into boiling steel (F), killed steel (Z), semi killed steel (b), and special killed steel (TZ);
(4) Carbon steel can be classified into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC 0.25-0.6%), and high carbon steel (WC>0.6%) based on their carbon content;
(5) According to the quality of steel, carbon steel can be divided into ordinary carbon steel (with high phosphorus and sulfur content), high-quality carbon steel (with low phosphorus and sulfur content), high-grade high-quality steel (with lower phosphorus and sulfur content), and special grade high-quality steel. Explanation: Generally, carbon steel with higher carbon content has greater hardness and strength, but lower plasticity.
