This is almost all the problems that manual car owners have paid attention to. In the case of emergency braking, is the distance between the brake pedal that only applies to the brake pedal is short or the distance between the brake pedal and the clutch pedal is short? In fact, in an extremely urgent situation, except for the old drivers who have particularly good driving skills, it is not uncommon for most people to accurately step on the brake pedal in this situation. Few people can remember to press the clutch with the brake pedal. Many articles have taught us that we shouldn’t coast at any time. The reason is that because of the lack of engine braking force due to the neutral gliding, the braking distance will be longer. Especially when a long downhill slope is used, only the brake pedal is used to control the speed. In an extremely dangerous manner, it is easy for the thermal decay of the brakes to reach the limit and eventually lose the braking force. So, according to this, if you press the clutch and brake in an emergency, isn't it equal to giving up the engine's anti-drag power? That's right, but you didn't think about it. Just stepping on the brakes is bound to shut down the manual car. Have you considered the various situations after the flameout? The first is that it is possible to face a secondary impact, and the second impact cannot be avoided because the vehicle has been extinguished. Second, under extremely severe circumstances, some people will experience the tragedy of the throttle when the brakes are applied, and the accelerator will continue. Destroyed, and thirdly, if at this moment it happens to be in a lower gear, such as a third gear, and only applies the brake pedal, the anti-drag power of the engine is relatively strong, which may very well interfere with the normal operation of ABS and cannot be completed. The ABS of the phasing mission cannot help you to control the car's trajectory. If you are on a slippery road, it is easy to skid over. Based on the above three points, only the clutch pedal and brake pedal are pressed at the same time in the case of emergency braking. In addition, it can be said with certainty that when the braking force reaches the limit, the engine's braking force is basically useless. In the case of normal ABS operation, these two methods of emergency braking can reduce the braking distance. There is no difference. Many European countries write down the action of two pedals at the same time as a standard in textbooks in case of an emergency. If you only brake on a road test and cause a flameout, you cannot get a driver's license. But how do you brake at the traffic light in the city's expressway? This situation and emergency stop can be two different things. For example, when a high-speed train encounters a sudden change of lights at the front intersection, there is still some room. At this time, the correct approach is to keep the stalls unchanged and step on the brakes. Use the engine traction and braking forces to quickly reduce the speed of the road. Removal, this is a short braking distance effective method, and in the small section of the car before the car really stopped, timely removal of the gear to maintain the state of low-speed neutral taxiing, can better speed and brake strength to do The final adjustment is for accurate parking, and it will not be awkward.

Centrifugally Ductile Cast Iron Pipe is a kind of pipe made from spherical graphite cast iron by centrifugal spinning process. The pipes, which can convey many fluid media such as water, oil and gas, are widely used in various pipeline projects for metallurgy, mine, water conservancy, petroleum and urban public service utility.
With its high strength, high elongation, corrosion resistance, resistance to shock, easy construction and many other fine features, ductile iron pipe is the best choice in today's world for conveying water and gas safely. Ductile iron, also called nodular iron or spheroidal graphite iron, is characterized by the presence of spheroidal graphite in the resultant castings.
Ductile iron pipes are available in a range of diameters from 80mm to 1600mm and are suitable for both potable water transmission and distribution (in accordance with BS EN 545) and sewerage (in accordance with BS EN 598).
Ductile iron pipes are simple to joint, can be laid in all weather conditions and often without the need for selected backfill. Its high safety factor and ability to accommodate ground movement make it the ideal pipeline material for a wide range of applications.
