Ladder


As the ancillary facilities of the city inspection shaft, for a long time, the ladder material has been made of steel. However, under many harsh environmental conditions, such as inspection wells, tunnels, chemical enterprises, rainy and humid occasions, the traditional metal ladder is very easy to rust, which affects the safety of use and has a short service life.

Gear ring


Forging can be used to apply pressure to the metal blank to produce plastic deformation and change its mechanical properties. Loose metal can be eliminated by forging. The holes improve the mechanical properties of the forgings.

Flange


Flange (Flange), also known as flange flange disc or flange. Flange is a part that connects between the shaft and the shaft, which is used for the connection between the pipe ends; it is also used for the flange on the import and export of the equipment, which is used for the connection between the two equipment, such as the reducer flange. Flange connection or flange joint refers to the detachable connection which is connected by flange, gasket and bolt as a group of combined sealing structure.

Forgings


Forging can be used to apply pressure to the metal blank to produce plastic deformation and change its mechanical properties. Loose metal can be eliminated by forging. The holes improve the mechanical properties of the forgings. Forgings have the following uses:

What are the quality control methods of forging production and processing in Shanxi forging factory


Roller forgings are widely used, and the working conditions are complex and diverse. In addition to the conventional mechanical properties, various rolling mills put forward a series of special requirements for the performance of the roller, which are different from other forgings. The surface of the roller body has to withstand fatigue caused by friction, wear, impact, contact stress and chilling and heating for a long time. During the rolling process, the roller body has to withstand high stress, mainly bending stress and friction. The main drive roller also bears huge torque.

Forging process and forging characteristics


Forgings by plastic deformation to shape the required shape or suitable compression force of the object. This is achieved by using a hammer or pressure. After forging, the structure and mechanical properties of the metal can be improved. The forging process can ensure the continuity of the metal fiber structure, make the fiber structure of the forging consistent with the shape of the forging, and the metal streamline is complete, which can ensure that the parts have good mechanical properties and Long service life.

Promote high-quality development with transformation and upgrading


From the "Hometown of Forging in China" to the "Capital of Flange Forging in the World", Dingxiang Flange has entered high-end fields such as nuclear power, deep-sea oil extraction, aerospace, and military industry. This is a report in Shanxi Daily not long ago. On August 11, there were media reports that the national flange forging product quality inspection center (Shanxi) passed the acceptance, which was the result of the provincial quality supervision bureau's active cultivation and incubation around the advantages of dingxiang flange and forging industry cluster. This is tantamount to tailor-made for Dingxiang flange, and it is also a good thing to promote high-quality development with transformation and upgrading. As a Dingxiang people, flange is always one of the biggest concerns of the author. To make a metaphor, flange is like Qin to Dingxiang

Stainless steel flange is a very good pipe parts


Stainless steel flanges are a very good pipe component. Due to the performance advantages of stainless steel itself, the application range of stainless steel flanges is very wide. The corrosion resistance of stainless steel flanges is very good, especially in some more complex environments.

Comparison of stainless steel and carbon steel flanges?


When using the electrode, it should be boring. The titanium calcium type should be dried at 150 ℃ for 1 hour, and the low a hydrogen type should be dried at 200~250 ℃ for 1 hour (it cannot be dried repeatedly, otherwise the coating is easy to crack and peel off), so as to prevent the coating of the electrode from sticking oil and other dirt, and avoid increasing the carbon content of the weld and affecting the quality of the welded parts. When flange pipe fittings are welded, carbides are separated by repeated heating, which reduces corrosion resistance and mechanical properties. Chrome flange pipe after welding hardening American standard flange is larger, prone to cracks. If the same type of chrome stainless steel electrode (GG207) is used for welding.

Basic introduction and use of flange


Flange joint is used in engineering design is very common, involving a very wide range of parts. It is an essential part of piping design, pipe fittings and valves, and is also an essential component of equipment and equipment parts (such as manholes, sight glass level meters, etc.). In addition, other professions such as industrial furnaces, thermal, water supply and drainage, heating and ventilation, automatic control, etc., also often use flange joints.
