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.

Recently, after 10 years of fierce fighting in domestic high-end light trucks, Qingling, Ao Ling, and JMC accounted for nearly 80% of the market share in the mid- to high-end light truck market, becoming the first camp of the light truck market, JAC, Dongfeng. The light truck series also showed a strong upward trend and entered the second camp. The third camp was occupied by small brands and the middle-to-high end light truck market formed a separatist situation. To a certain extent, the appearance of the "three bells" phenomenon depends on "high-speed and heavy-loading," and this commonality has gradually become a standard for high-end light trucks in the post-light-card era. Experts from the industry pointed out that from the “three-ling†market, it can be seen that “high-speed and heavy-duty†has become an important indicator for the purchase of light trucks, and it also reflects the current tendency of domestic consumers to choose mid- to high-end light trucks.
"Three bells" competition, go "high speed" road
A senior dealer of light trucks is outspoken: "Actually, the best-selling vehicles in the mid-to-high-end light truck market are all in line with the characteristics of high speed and heavy load." The car needs to be able to decorate more quickly and run faster, so as to bring greater benefits to itself. With the rapid development of domestic road conditions in recent years, and as energy prices continue to rise, many consumers come to buy cars. The first consideration is whether they can pull more and run faster.
The "three bells" cater to the market, eventually embarked on the "high-speed" road, and to the direction of "heavy load", behind which is the result of market competition. According to industry insiders, before Ao Ling joined the mid- to high-end light truck competition, Jiangling and Qingling, relying on the origin of Japanese Isuzu technology, staged a "double-handed society" with high-speed performance in the high-end light truck market. In order to enter the game, Olling has integrated the superior technologies of more than a dozen companies in China, Japan and Europe in order to create the first light truck high-speed platform products in China. It has also achieved outstanding performance in heavy load capacity. So far in the same category of light trucks second to none, and led Jiangling, Qingling upgrade on the heavy load.
According to the person in charge of Olympic Bell, the "high-speed and heavy-duty" is mainly manifested in two aspects: On the one hand, under the same load quality conditions, Ao Ling has a higher speed, on the other hand, under the same speed, Ao Ling has Higher carrying capacity. After the technical experts tested the "Aoao Bell" and the "Big Ao Ling", they agreed that because the Olympic Bell is equipped with a supercharged intercooled engine, the power can be increased by up to 14.8%, the speed can be increased by up to 15.6%, and the maximum torque can be increased by 29.7%. On the whole vehicle matching optimization, the reserve torque at the low speed increases, the maximum acceleration performance of the vehicle can be increased by 6.7%; the frame adopts new materials, the structure is optimized, the suspension and the axle are matched and upgraded, and the safety braking system is matched to realize more Load. Obviously, this method of Olling caters to consumer demand to widen and heighten the body, leading the Chinese light trucks to speed up, and is now being sought after by the market. In just over a year, Olling made a major breakthrough in the market, with Qingling and Jiangling together with a market share of 25%, forming a pattern of “three kingdoms†fighting for hegemony of domestic medium and high-end light trucks.
The fight for hegemony, the pursuit of "the era of light trucks"
Automobile expert Jia Xinguang pointed out that "Sanling" can become the market overlord, and the grasp of consumer demand behind it is very important. Judging from the current situation, "three bell" has objectively formed a "three bell standard", and its core is "high speed and heavy load." This standard has also become a technical “watershed†between the first camp and followers of domestic high-end light trucks at this stage. Now that the industry standards are transparent, the direction of followers is even clearer. It is foreseeable that the light truck manufacturers outside “Sanling†will certainly accelerate the pace of moving closer to the “three bells standardâ€. In the second half of the year, China’s high-end light trucks have risen rapidly, setting off an upsurge in speeding up and increasing loading space.
However, some technical experts pointed out that the technical threshold for "high-speed and heavy-duty" is not low. Take Auling's "heavy-duty" capability as an example. Only the chassis uses the Isuzu-enhanced undercarriage integrated with German technology. Careful adjustment and second optimization and upgrading, greatly enhance the carrying capacity, power increased by more than 20%, the maximum climbing grade reached 30%, called the Chinese box-type first chassis. "High-speed and heavy-duty" has higher requirements on chassis, engines and other aspects, and it is a test for the strength of light truck companies. It is understood that like Qingling, Ao Ling and Jiangling have a high technical content, comprehensive ability is second to none in light trucks. To this end, Qingling and Jiangling have also upgraded their technology on the basis of the introduction of Japan's Isuzu technology. Olling has concentrated on its superior resources and has jointly researched and developed over a dozen Chinese and foreign companies. It can be seen that the technical skills of the "Three Bells" have been accumulated over the years, and followers who want to compete with the "Three Bells" must not be able to do so overnight. It can be foreseen that in the long period after the light truck era, the domestic high-end light truck market will still be the stage of the “three bellsâ€.
The relevant authorities commented directly that under the guidance of Ao Ling’s initiative of “high-speed and heavy-dutyâ€, “Sanling†achieved a complete upgrade in the competition, raising the domestic high-end light trucks to a higher level and objectively targeting China’s light trucks. Development has injected catalysts.
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.
