Experienced aerial vehicles and old drivers are recruiting strokes. In order to avoid the above situations, the novice must psychologically overcome the nervous and scared feelings, and easily face the car. The correct car must be prepared in advance to avoid the mentality of the car. Panic and operational hurry.
To do this, you will want to see two counts and three slows before your vehicle: At first glance, you will see the model, speed, and loading of the car, the width and solid condition of the road ahead, the pedestrians and vehicles along the road, and the on-street parking. And obstacles, etc.; second calculation, through the observation and comparison, to estimate the approximate location of the two vehicles at the time of intersection, the road situation, in order to leave a suitable horizontal safety interval; three slow, that is, when the car will slow down, approaching Poor conditions in the meeting should be to control the speed, not blindly meet, if necessary, should be the first stop. In addition, the car will also pay attention to the rules of the transfer, and timely and reasonable to allow line. At night there is no street lighting or poor lighting on the road, will When driving the vehicle, switch off the high beam and switch to the low beam.
Boiler tubes is a one of seamless pipe. Manufacturing methods is the same as seamless tube, but it has the stringent requirements for manufacture of steel pipes. According to the temperature level,boiler tube is divided into general boiler tubes and high pressure boiler tube.
Production methods:
①general boiler tube temperature is below 350 ℃, using hot-rolled pipe or cold drawn tube manufacture Steel Pipe.
â‘¡ high-pressure boiler tube is used often in conditions of high temperature and high pressure pipe, the effect of high temperature flue gas and water vapor, oxidation and corrosion. Steel pipe with high rupture strength, high resistance to oxygen corrosion and have good organizational stability.
Boiler tubes purposes:
â‘ general boiler tubes is mainly used to manufacture water wall tubes, tubes in boiling water and super heated steam pipe, super heated steam locomotive boiler tubes, large and small smoke pipe and pipe arch brick.
â‘¡ high-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guide tubes, main steam tubes, etc. for high-pressure and ultra-high-pressure boilers
Category:
General boiler tubes and high pressure boiler tube boiler tubes is exposed to high temperature performance. Boiler tubes in general, or high-pressure boiler tubes according to their use can be divided into a variety of steel pipe.
