Flange standard system

Time：

2021-11-12

There are mainly two systems for international pipe flange standards, namely the European pipe flange system represented by German DIN (including the former Soviet Union) and the American pipe flange system represented by American ANSI pipe flange. In addition, there are Japanese JIS pipe flanges, but they are generally only used for public works in petrochemical plants, and have little international influence. The pipe flanges of various countries are briefly introduced as follows:

1. European system pipe flanges represented by Germany and the former Soviet Union 2. American system pipe flange standards, represented by ANSIB16.5 and ANSIB16.47 3. British and French pipe flange standards, each with two sets Pipe flange standard.

To sum up, the internationally accepted pipe flange standards can be summarized as two different and non-interchangeable pipe flange systems: one is the European pipe flange system represented by Germany; the other is represented by the United States. American pipe flange system.

IOS7005-1 is a standard promulgated by the International Organization for Standardization in 1992. This standard is actually a pipe flange standard that combines two series of pipe flanges from the United States and Germany.

Points to pay attention to when designing flanges

Flange is also called flange flange or flange. Flanges are parts that connect shafts to shafts and are used to connect pipe ends; they are also used for flanges on the inlet and outlet of equipment and the connection between two equipment, such as reducer flanges.

What are the safety hazards of installing flanges in cars?

Non-players are not recommended to install flanges. The potential safety hazard is that once the flange screws are loose and broken, the wheels will fall off. The probability is very low, and after the screw is loosened, the old driver can feel the wheel shaking, and stopping in time can avoid accidents. However, the harm of installing inferior flanges is relatively large. For example, the screws are not loose and broken, but the flange is broken due to insufficient strength! At this time, the wheels must fly out, and the vehicle is in danger of losing control.

What is the optimal thickness of the flange installed on the car?

The optimal thickness of the flange installed on the car is between 25 and 30mm. Adding the flange will increase the coaxial wheelbase of the car, and the grip ability will also become stronger when driving, thus greatly improving the car's ability to handle sharp turns. Excellent stability, not prone to sideslip phenomenon, so that driving safety can be improved. After the vehicle is equipped with a flange, the rim of the car tire will be flush with the fender, and the car will look more dynamic and the visual effect will be better. The installation of flanges can balance the center of gravity of the car body and make the car more stable when driving. It is mostly used to prevent the car from slipping when turning sharply, causing danger.

Tensioner accessories supplier: structure of tensioner accessories

According to the tensioner accessories supplier , the tensioner accessories are divided into accessory tensioner (generator belt tensioner, air conditioner belt tensioner, supercharger belt tensioner, etc.) and timing belt tensioner. The tensioning wheel is mainly divided into mechanical automatic tensioning wheel and hydraulic automatic tensioning wheel according to the tensioning method. The tensioning wheel is mainly composed of a fixed housing, a tensioning arm, a wheel body, a torsion spring, a rolling bearing and a spring sleeve. The tension can be adjusted automatically according to the degree of belt tightness, so that the transmission system is stable, safe and reliable. The tightening ring is a vulnerable part such as auto parts. The belt is easy to wear after a long time. The belt runs more smoothly, makes less noise, and prevents slipping.
