銲接（jiē）無縫鋼管也稱焊管，是用謄寫鋼版或（huò）帶鋼經曆卷起有關成型後銲接（jiē）釀成的無縫（féng）鋼管。銲接無縫（féng）鋼管製（zhì）造工藝更為簡便，製造效率高，栽培品（pǐn）種規格多，設備資少，但通常（cháng）極限抗拉強度（dù）不可企及無縫無（wú）縫鋼管。銲接無縫鋼管按焊縫的方式進行劃成直縫焊管和螺旋形焊管。
Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip after coiling and forming. 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. Welded steel pipe is divided into straight welded pipe and spiral welded pipe according to the form of weld.
銲接無縫鋼管使用（yòng）的毛坯是謄寫鋼版或帶鋼，因其銲接生產工藝有所區別而（ér）進行劃成爐焊管、電弧焊（阻（zǔ）力焊（hàn））管和自（zì）動化電弧（hú）焊管。因（yīn）其銲接方（fāng）式的有所區別進（jìn）行劃成直縫焊（hàn）管（guǎn）和螺旋形焊管關於兩種。因其端部幾何形狀又進行劃成圓圈焊管和異型（方、扁等）焊管。焊管因其材料和（hé）用處有所區別而進行劃成如下多少（shǎo）栽（zāi）培品種：
The billet used in welded steel pipe is steel plate or strip. It is divided into furnace welded pipe, electric welded pipe and automatic arc welded pipe because of different welding technology. Because of its different welding forms, it can be divided into straight welded pipe and spiral welded pipe. Because of its end shape, it can be divided into circular welded pipe and special-shaped (square, flat, etc.) welded pipe.

It is mainly used for conveying low pressure fluids such as water, sewage, gas, air, heating steam and other purposes. Its representative material is grade Q235A steel.

另有，裝飾品用銲接（jiē）不鏽無縫鋼管（GB/T 18705-2002），建築物裝飾品（pǐn）用不鏽鋼銲接管（guǎn）材（JG/T 3030-1995），低氣壓半流體輸氣用大有（yǒu）關直徑電弧（hú）焊無縫鋼管（GB/T 3091-2001），還有換（huàn）熱鋪（pù）謀定計銲接無（wú）縫鋼管（YB4103-2000）。

直縫焊管製造工藝更為簡便，製造效率高，費（fèi）用成本低，持續發展較快。螺旋形焊管（guǎn）的極（jí）限抗拉強度通常比直縫焊管高，能（néng）用較窄的（de）毛坯生產管徑更加較大的焊管，還能夠用同樣地幅度的毛坯生產管（guǎn）徑有所區別的焊管（guǎn）。不過與雷（léi）同長度的直縫管比較起來，焊縫長度增添30~100%，並（bìng）且生產運行速度較低。
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.
因為這個原因，較飲啜（chuò）徑的焊管大（dà）都使用直縫焊，花木徑焊管則大半使用螺旋形焊。
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.
進行補語：焊管是（shì）用帶鋼（gāng）銲接（jiē）的，因此在戛戛獨造（zào）它的所處位置沒無縫管高。
Supplementary: Welded pipe is welded with strip steel, so it is not as high as seamless pipe in its original position.
