Forging temperature range refers to the temperature interval between the initial forging temperature and the final forging temperature. In order to improve the plasticity and reduce the deformation resistance, we hope to increase the heating temperature of metal as much as possible; However, in order to ensure product quality and avoid defects in heating, the

In fact, at the beginning, all the wheels were made of wood or iron. Later, rubber tires were invented. Rubber tires can play a good role in shock absorption on uneven roads. But the train has been running on the track, there is no need for rubber tires. The train was invented before the car.

The blind flange is also called the 8-word blind plate, as its name implies, its shape is like 8 words, it is a blind plate at one end, the other end is a combination of throttle ring, in the transport of fluid, the use of throttle ring, cut off when the use of blind plate,

1. The flange of pressure vessel can be divided into general flange and reverse flange according to the overall structure of flange. 2. According to the type of flange gasket arrangement, we can divide it into narrow face flange and wide face flange. a. Narrow face flange refers to the gasket contact surface, located in

The basic principle and performance characteristics of the socket pipe fittings The other is that there is no less to negotiate in the pipeline. Root, also called the root hoop, lock nut, with one end for the short wire buckle, the other end for the long thread buckle short pipe and a root mother, plus

Austenitic stainless steel is softened by solid solution, the steel wire is generally heated to 950 around, heat preservation for a period of time, so that carbide and various alloying elements fully homogeneous dissolved in the Huaux, and then rapid quenching water cooling, carbon and other alloying elements of the precipitate, to obtain pure austenite,

Stainless steel materials are basically corrosion-resistant. At the same time, compared with other metal products, the corrosion resistance is better. Compared with stainless steel square tube, the corrosion resistance is needless to say. However, after long-term use, corrosion and rust can not be avoided, and there are many factors that damage the corrosion resistance, not

Pipe fittings Use of value and range pipe fittings the welding of dissimilar metals can save precious metal and make the product function better. For example, the work of the tool parts (high-speed steel) and tail (medium carbon) of the butt welding, internal combustion engine exhaust valve head (heat-resisting steel) and the tail (structural steels)

The corrosion resistance of stainless steel flanges in all kinds of tubes is the best, because stainless steel flanges can be deactivated with oxidants, forming a layer of tough dense chromium-rich oxide protective film $literal on the surface, thus effectively preventing the further occurrence of the oxidation reaction. Stainless steel flange corrosion is usually manifested

Carbon steel flange storage is very important, the general project will choose carbon steel quality, carbon steel flange surface is very easy to appear floating rust, placing time long appearance is not beautiful, the storage of flanges shall not be placed directly on the ground, put the ground into some moisture-proof cushion, and then put
