    Ⅰ。支撑螺纹 -这种类型的螺纹轮廓用于管道和井筒工具。它还可用于尾管和套管。螺纹的轮廓通常是方形切割形状。 When the thread comes in contact with the mating thread, a hydraulic seal is created through interference fit which allows the buttress-threaded equipment to lock firmly.

    Ⅱ.Round Thread – This thread profile is made for the tools and components used in slickline operations. It is also known as a knuckle thread. It is robust and can cause minimal wear and tear by dirt and other impurities inside the wellbore because of its round shape. The Round Thread profile is prepared as per API tubing grades. Round threads can be further divided into two types, i.e., Long Round Thread Profile and Short Round Thread Profile.

    不锈钢是一种多功能材料,由钢合金和少量铬组成,添加铬可提高材料的耐腐蚀性,这一特性使不锈钢得名。由于不锈钢也具有低维护性、抗氧化性,并且不影响与之接触的其他金属,因此它经常被广泛应用,尤其是在管道和管材制造中。根据管道的最终用途,不锈钢管道可分为几类。

    管道有时很难分类,并且往往根据功能进行区分。除了这些分类之外,不锈钢还根据类型和等级进行区分。

    1.304不锈钢管

    用于管材和管道乐动app下载安装应用,304型不锈钢是一种常见的选择,因为它具有高度的耐化学性和耐腐蚀性。然而,304型不锈钢不适用于温度在800至1640华氏度(F)之间的应用,因为它容易产生碳化物沉淀,这是材料碳含量限制为0.08%的结果。304L型不锈钢避免了这一问题,因为它具有较低的碳含量限制,因此可用于焊接和高温应用。其他类型的不锈钢通常含有添加剂(如镍或钼),这些添加剂可增强特定应用中所需的特性。

    2.用于一般耐腐蚀性的不锈钢管

    这种一般类型的钢适用于要求耐腐蚀性高于其他特性的应用。铁素体或马氏体类型的钢(铬含量最高的钢)可进行热处理或退火。奥氏体不锈钢(铬和镍含量高的不锈钢)具有更高的电阻,可在与铁素体和马氏体类型相同的一般条件下使用。

    3.不锈钢压力管

    这种不锈钢管由固体铬或铬镍混合物制成。不锈钢压力管的类型包括无缝和焊接管、高压应用的电熔焊管、腐蚀或高温应用的大直径焊接管,以及无缝和焊接铁素体和奥氏体不锈钢管。/p>

    4。7.Aircraft Hydraulic-Line Tubing

    Another type of aircraft tubing, aircraft hydraulic-line tubing is used in aerospace applications as fuel-injection lines and hydraulic systems, and tends to be small. It is often manufactured from types 304 or 304 L stainless steel because of the steel’s high-strength, corrosion-resistance, and ductility.

    区分焊接钢管与无缝钢管主要有四种方法:1.焊接钢管与无缝钢管;金相法是区分焊接钢管和无缝钢管的主要方法之一。高频电阻焊接钢管不添加焊接材料,所以焊接钢管的焊缝很窄,如果采用粗磨和腐蚀的方法,焊缝看不清楚。高频电阻焊钢管一旦焊接而不热处理,焊缝结构将与钢管母材产生根本的不同。在[& # 8230;]< / p > < p >的< rel =“nofollow”href = " //www.gh-pc.com/line-pipe/identification-method-of-seamless-steel-pipe-and-welded-steel-pipe/ " >识别方法的无缝钢管和焊接钢管< / >第一次出现在< rel =“nofollow”href = " //www.gh-pc.com " >要求钢管制造商,天然气套管和管道,无缝钢管,OCTG,.

    <跨度类=“苹果式跨度”>有从无缝钢管区分焊接钢管四种主要方法:

    <跨度类=“苹果风格 -跨度“> 1。金相法

    <跨度类=“苹果式跨度”>金相法是主要的方法从无缝钢管区分焊接钢管之一。高频电阻焊接钢管不添加焊接材料,所以焊接钢管的焊缝很窄,如果采用粗磨和腐蚀的方法,焊缝看不清楚。高频电阻焊钢管一旦焊接而不热处理,焊缝结构将与钢管母材产生根本的不同。此时,金相方法可以用来区分焊接钢管和无缝钢管。区分两种钢管的过程中,有必要切小样品长度和40毫米的宽度,在焊接,大致磨,细磨和抛光它们,然后把它们金相显微镜下观察的结构。当铁素体和魏氏组织,母材和焊接区的结构中观察到,焊接钢管和无缝钢管可以精确区分。

    <跨度类=“苹果式跨度”> 2。腐蚀方法
    在用腐蚀方法从无缝钢管区分焊接钢管的过程中,焊接钢管的焊缝应打磨。抛光后,抛光的痕迹应该可以看到。然后端面应当在焊缝砂纸进行抛光,和端面应用5%的硝酸酒精溶液进行处理。 If there is an obvious weld seam, the end face should be polished with sandpaper at the weld seam. It can be proved that this steel pipe is welded steel pipe. There is no significant difference in the end face of seamless steel tube after corrosion.
    Performance of Welded Steel Pipe
    Welded steel pipe has the following properties because it is processed by high frequency welding and cold rolling.
    First, the thermal insulation function is good. The heat loss of welded steel pipe is relatively small, only 25%, which is not only conducive to transportation, but also reduces the cost.
    Secondly, it is waterproof and corrosion-resistant. In the process of Engineering construction, it is not necessary to install pipe trenches alone, but to bury the pipe directly underground or underwater, which reduces the construction difficulty of the project.
    Thirdly, it has impact resistance. Even at low temperature, the steel pipe will not be damaged, so its performance has certain advantages.
    Performance of Seamless Steel Pipe

    Because of the high tensile strength of the seamless steel tube metal material, its anti-destruction ability is stronger, and it has hollow passage, so it can effectively transport fluid, it is its strong transport ability, so seamless steel tube has higher corrosion resistance than welded steel tube, and its stiffness is relatively large. Therefore, the more load the seamless steel tube bears, so it can be widely used in projects with higher construction requirements.

    3. Identify welded and seamless steel tubes according to process

    In the process of distinguishing welded steel pipe and seamless steel pipe according to technology, all welded steel pipe is welded according to cold rolling and extrusion. In addition, spiral pipe welding and straight seam pipe welding will be formed when high frequency and low frequency arc welding pipe and resistance welding pipe are used to weld steel pipe, and circular and square pipe will be formed. Elliptical steel pipe, triangular steel pipe, hexagonal steel pipe, rhombic steel pipe, octagonal steel pipe, and even more complex steel pipe. In a word, different shapes of steel pipes will be formed by different processes, so that welded steel pipes and seamless steel pipes can be distinguished clearly. However, in the process of identifying seamless steel pipes according to technology, it is mainly based on hot rolling and cold rolling treatment, and seamless steel pipes also have two main forms, namely hot-rolled seamless steel pipes and cold-rolled seamless steel pipes. Hot-rolled seamless steel pipes are formed by piercing and rolling, especially large diameter and thickness seamless steel pipes are welded by this process; cold-drawn pipes are cold-drawn by tube blanks, which have lower strength, but smooth external and internal control surfaces.

    4. Distinguishing welded and seamless steel pipes by use
    Welded steel pipe has higher flexural and torsional strength and more load-bearing capacity, so it is widely used in the manufacture of mechanical parts. For example, oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction are all made of welded steel pipe. However, seamless steel pipe can be used as a pipeline for conveying fluids because of its hollow section and long steel without joints around it. For example, it can be used as a pipeline to transport oil, natural gas, gas, water and so on. In addition, the bending strength of seamless steel tube is relatively small, so it is widely used in superheated steam pipes of low and medium pressure boilers, boiling pipes and superheated steam pipes for locomotive boilers.
