ERW Pipe Mills are steel pipe making machines, continuously make steel pipes from steel strips. The pipe making process is uncoiling, joint welding, forming, high frequency welding, sizing, fly saw cutting and stacking.
The steel pipe forming machine and sizing machine is the main machine, high frequency welding equipment is the critical equipment to ensure ERW pipe quality.
The ERW pipe production line contain a lot of equipments, each equipment is professionally customized, e.g. automatic forming, convenient rollers changing, hot saw or cold saw, automatic pipe stacking and packing, etc..

Speaking of tire parameters, many of my friends have come into contact with the parameters we often use when shopping for tires, such as 245/45 R18, etc., but have you noticed that in addition to these parameters, there are many other parameters on the tire? These contents have a very important role in our daily driving and the use of tires. These contents may be easily overlooked by us. Today, the editor took everyone together to interpret these "passwords on the tire."
The function of the tires is not to carry the shoes of the body, can you run with us? Obviously not that simple, here we come to understand what is the use of the tire: Function The main function of the tire is to carry the weight of the body, followed by shock absorption, whether it is Alto, Audi, or Ferrari, Bugatti, let the vehicle strong again Performance, if not carried by the tire, will only become a "car model" that cannot be moved.
In terms of shock absorption and lifting, we may think of a shock absorber in a vehicle suspension system. In fact, the tire is also responsible for reducing and alleviating the effects of vehicle vibration and noise while the vehicle is traveling.
The characteristics of the vehicle's acceleration performance, braking performance and steering performance have different performances through different patterns and formulas. The performance of different formulations and positioning tires in these three aspects will be significantly different.
The three parameters most frequently contacted when purchasing a tire are the wider the width of the tire and the larger the ground contact area. Under the premise of the same pattern and the same material, the grip and traction of the tire with a larger width in the straight driving condition will be more Yes, but the fuel consumption level will increase accordingly, so we must weigh the pros and cons when we regularly replace and upgrade tire specifications.
The flat ratio refers to the ratio of the height from the rim to the tread to the maximum width of the tire's cross-section measurement, expressed as a percentage, that is, the height as a percentage of the width.
Regarding the flatness ratio, most of the commercially available cars use more tires having a small width, a small inner diameter, and a large flatness ratio. Flat tires with large specific values ​​have a long sidewall and strong cushioning capacity, and they are relatively comfortable. However, they give poor feedback on road conditions and have weak lateral resistance during cornering. On the other hand, tires with smaller flat ratios and larger inner diameters have a thinner tire wall, better feedback to the road surface, and a smaller change in the shape of the tire wall, which greatly enhances the handling of the vehicle. They are often used in vehicles with a biased sport style.
R stands for the radial tire, and the radial tire refers to the direction in which the inner braid braid of the tire is aligned with the centerline of the tread at 90 degrees, named after the meridian on the globe. Generally, the crown portion of the tire will increase the wire layer, so that it can withstand greater internal pressure stress, with the tread is not easy to deform, better ground grip and stability characteristics, more suitable for high-speed driving. Radial tires are now commonly used in cars.
