大富彩票平台所谓的厚壁焊管,其主要的消费原理在于:大口径厚壁焊管是在再结晶温度以上停止轧制,冷轧是在再结晶温度一下轧制。之所以称之为厚壁焊管,是把钢管外径和壁厚之比小于20的钢管成为厚壁焊管。主要的是用作石油地质钻探管、石油化工用裂化管、锅炉管、轴承管以及汽车、拖拉机、航空用高精度构造管等等。

The main consumption principle of the so-called thick-walled welded pipe is that the large-caliber thick-walled welded pipe stops rolling above the recrystallization temperature, and the cold rolling is rolling at the recrystallization temperature. The reason why it is called thick-walled welded pipe is that the ratio of outer diameter to wall thickness of steel pipe is less than 20 to become thick-walled welded pipe. Mainly used for petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes and high-precision structural pipes for automobiles, tractors, aviation and so on.

大富彩票平台一、厚壁焊管与薄壁焊管的区别?

1. The difference between thick-walled welded pipe and thin-walled welded pipe?

厚壁焊管和薄壁焊管的大区别望文生义就是“壁厚”的厚度。普通来讲,薄壁焊管都是冷拔技术,而厚壁焊管则运用的是热轧技术。假如用度量单位来辨别,普通以为厚壁/管径等于0.05是厚壁钢管和薄壁钢管的分水岭。壁厚/管径小于0.05的是薄壁钢管。大于的是厚壁钢管。在用处上来讲,薄壁焊管多用于管道上,而厚壁焊管则多用于空心零件的坯料。承压以及重要管道上运用。

The biggest difference between thick-walled welded pipe and thin-walled welded pipe is the thickness of "wall thickness"。 Generally speaking, thin-walled welded pipe is cold-drawn technology, while thick-walled welded pipe is hot-rolled technology。 If the unit of measurement is used to distinguish, it is generally believed that the thickness/diameter of thick-walled pipe is equal to 0。05, which is the watershed between thick-walled pipe and thin-walled pipe。 Thin-walled steel tubes with wall thickness/diameter less than 0。05。 Thick-walled steel pipes are larger。 In terms of usage, thin-walled welded pipes are mostly used in pipes, while thick-walled welded pipes are mostly used in blanks of hollow parts。 Pressure bearing and important pipeline application。

二、厚壁焊管在工程运用中应当恪守的相关规则?

2. Relevant rules that thick-walled welded pipe should abide by in engineering application?

首先,厚壁管件在实践选用或者运用的时分,必需遵照相应法规以及标准内的各项规则,特别是保送极度或高度危害流体介质、仍然介质以及高压气体等管道的场所。在这些前提下,主要的根据用处和运用条件,像是压力、温度、流体等来肯定管件的品种。

Firstly, when choosing and applying thick-walled pipe fittings in practice, it is necessary to abide by relevant regulations and rules in the standards, especially in places where pipelines such as highly or highly hazardous fluid medium, still medium and high-pressure gas are delivered. On these premises, the main basis of the use and operating conditions, such as pressure, temperature, fluid, etc., to determine the type of pipe fittings.

三、厚壁焊管的主要用处?

3. The main use of thick-walled welded pipe?

厚壁焊管主要的应用于自来水工程、石化工业、化学工业、电力工业、农业灌溉、城市建立。用作液体保送用:给水、排水。用作气体保送用:煤气、蒸汽、液化石油气。用作构造用:打桩管,做桥梁可用于:码头、道路、建筑构造用管等等方面。

大富彩票平台Thick-walled welded pipes are mainly used in tap water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction. For liquid delivery: water supply and drainage. For gas delivery: gas, steam, liquefied petroleum gas. Used for construction: Pile driving pipe, bridge can be used for wharf, road, construction pipe and so on.
