Dangerous factors and main causes in forging production
1、 In forging production, external injuries that are prone to occur can be divided into three types according to their causes: mechanical injuries - scratches or bumps directly caused by tools or workpieces; Scald; Electric shock injury. 2、 From the perspective of safety technology and l...Read more -
What is forging? What are the advantages of forging?
Forging is a metal processing technique that mainly applies external forces to cause plastic deformation of metal materials during the deformation process, thereby changing their shape, size, and microstructure. The purpose of forging can be to simply change the shape of the metal,...Read more -
What are the methods of forging and forming?
Forging forming method: ① Open forging (free forging) Including three types: wet sand mold, dry sand mold, and chemically hardened sand mold; ② Closed mode forging Special casting using natural mineral sand and gravel as the main molding material (such as investment ca...Read more -
What is the basic classification of forging?
Forging can be classified according to the following methods: 1. Classify according to the placement of forging tools and molds. 2. Classified by forging forming temperature. 3. Classify according to the relative motion mode of forging tools and workpieces. The prepara...Read more -
What are the differences between casting and forging?
Casting and forging have always been common metal processing techniques. Due to the inherent differences in the processes of casting and forging, there are also many differences in the final products produced by these two processing methods. A casting is a material that is cast as a whole in a mo...Read more -
What are the heat treatment forms for stainless steel forgings?
Post forging heat treatment of stainless steel forgings, also known as first heat treatment or preparatory heat treatment, is usually carried out immediately after the forging process is completed, and there are several forms such as normalizing, tempering, annealing, spheroidizing, solid solutio...Read more -

What are the precautions for flange installation?
The main precautions for flange installation are as follows: 1) Before installing the flange, the sealing surface and gasket of the flange should be inspected and confirmed to ensure that there are no defects that affect the sealing performance, and the protective grease on the flange sealing sur...Read more -
What factors need to be considered when selecting the pressure rating of the connecting flange ?
1. The design temperature and pressure of the container; 2. The connection standards for valves, fittings, temperature, pressure, and level gauges connected to it; 3. The influence of thermal stress on the flange of the connecting pipe in process pipelines (high-temperature, thermal pipelines); 4...Read more -
Pressure rating of flanges
A flange, also known as a flange or flange. A flange is a component that connects shafts and is used for connecting pipe ends; Also useful are flanges on the inlet and outlet of equipment, used for connecting two devices, such as gearbox flanges. A flange connection or flange joint refers to a de...Read more -
Seven common causes of flange leakage
1. Side opening Side opening refers to the fact that the pipeline is not perpendicular or concentric with the flange, and the flange surface is not parallel. When the internal medium pressure exceeds the load pressure of the gasket, flange leakage will occur. This situation is mainly caused durin...Read more -
What are the causes of forming cracks and defects in forging process?
The mechanism analysis of crack inducement is conducive to mastering the essential reason of crack, which is the objective basis for crack identification. It can be observed from many forging crack case analysis and repeated experiments that the mechanism and characteristics of alloy steel forgin...Read more
