公司基本資料信息






詳細說明
 焊接鋼管是指用鋼帶或鋼板彎曲變形為圓形、方形等形狀后再焊接成的、表面有接縫的鋼管。
Welded steel pipe is a kind of steel pipe with joints on its surface after bending and deformation of steel strip or steel plate into circular or square shape.
焊接鋼管生產工藝簡單,生產效率高,品種規格多,設備資少,但一般強度低于無縫鋼管。20世紀30年代以來,隨著優質帶鋼連軋生產的迅速發展以及焊接和檢驗技術的進步,焊縫質量不斷提高,焊接鋼管的品種規格日益增多,并在越來越多的領域代替了無縫鋼管.
Welded steel pipe has the advantages of simple production process, high production efficiency, many varieties and specifications and less equipment, but its general strength is lower than that of seamless steel pipe. Since the 1930s, with the rapid development of high-quality strip continuous rolling production and the progress of welding and inspection technology, the quality of weld seam has been continuously improved, the variety and specification of welded steel pipe has been increasing, and seamless steel pipe has been replaced in more and more fields.

焊接鋼管 按焊接方法不同可分為電弧焊管、高頻或低頻電阻焊管、氣焊管、爐焊管、邦迪管等。按焊縫形狀可分為直縫焊管和螺旋焊管。
Welded steel pipe can be divided into arc welded pipe, high frequency or low frequency resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe and so on according to different welding methods. According to the weld shape, it can be divided into straight welded pipe and spiral welded pipe.
電焊鋼管用途
Application of Welded Steel Pipe
用于石油鉆采和機械制造業等。爐焊管可用作水煤氣管等,大口徑直縫焊管用于高壓油氣輸送等;螺旋焊管用于油氣輸送、管樁、橋墩等。焊接鋼管比無縫鋼管成本低、生產效率高。直縫焊管生產工藝簡單,生產效率高,成本低,發展較快。螺旋焊管的強度一般比直縫焊管高,能用較窄的坯料生產管徑較大的焊管,還可以用同樣寬度的坯料生產管徑不同的焊管。但是與相同長度的直縫管相比,焊縫長度增加30~100%,而且生產速度較低。因此,較小口徑的焊管大都采用直縫焊,大口徑焊管則大多采用螺旋焊。
It is used in oil drilling and production, machinery manufacturing, etc. Furnace welded pipe can be used as water gas pipe, large diameter straight seam welded pipe for high pressure oil and gas transmission, spiral welded pipe for oil and gas transmission, pipe pile, pier and so on. Welded steel pipe has lower cost and higher production efficiency than seamless steel pipe. Longitudinal welded pipe has the advantages of simple production process, high production efficiency, low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe. It can produce welded pipe with bigger diameter with narrower blank, and welded pipe with different diameter can also be produced with blank of the same width. However, compared with the straight seam pipe of the same length, the length of the weld increases by 30-100%, and the production speed is lower. Therefore, most of the smaller diameter welded pipes are welded by straight seam welding, while the larger diameter welded pipes are mostly welded by spiral welding.
