1.高壓流體保送用鍍鋅焊接鋼管也稱鍍鋅電焊鋼管，俗稱白管。是用于保送水、煤氣、空氣油及取暖蒸汽、暖水等普通較高壓力流體或其他用處的熱浸鍍鋅焊接爐焊或電焊鋼管。鋼管接壁厚分爲普通鍍鋅鋼管和加厚鍍鋅鋼管;接收端方式分爲不帶螺紋鍍鋅鋼管和帶螺紋鍍鋅鋼管。鋼管的規(guī)格用公稱口徑mm表示，公稱口徑是內徑的近似值。

1. Galvanized welded steel pipes for high-pressure fluid delivery are also called galvanized welded steel pipes, commonly known as white pipes. It is used for hot dip galvanizing welding furnace welding or electric welding steel pipe for conveying water, gas, air oil, heating steam, warm water and other common high pressure fluids or other uses. The wall thickness of steel pipe can be divided into common galvanized steel pipe and thick galvanized steel pipe. The receiving end can be divided into non-threaded galvanized steel pipe and threaded galvanized steel pipe. The specification of steel pipe is expressed by nominal diameter mm, which is the approximate value of inner diameter.

2.普通碳素鋼電線套管是工業(yè)與民用修建、裝置機器設備等電氣裝置工程中用于維護電線的鋼管。

2. Common carbon steel wire sleeve is a steel pipe used for maintenance of electric wires in industrial and civil construction, installation machinery and equipment and other electrical installations.

3.直縫電焊鋼管是焊縫與鋼管縱向平行的鋼管。通常分爲公制電焊鋼管、電焊薄壁管、變壓器冷卻油管等等。

3. Longitudinal welded steel pipe is a steel pipe with longitudinal parallel weld and steel pipe. Usually it is divided into metric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe and so on.

4.承壓流體保送用螺旋縫埋弧焊鋼管是以熱軋鋼帶卷作管坯，常常溫螺旋成型，用雙面埋弧焊法焊接，用于承壓流體保送的螺旋縫鋼管。鋼管承壓才能強，焊接功能好，經過各種嚴厲的迷信檢驗和測試，運用平安牢靠。鋼管口徑大，保送效率高，并可浪費鋪設管線的投資。次要用于保送石油、自然氣的管線。

4. Spiral submerged arc welded pipe for pressure fluid delivery is a kind of spiral welded pipe, which is made of hot rolled steel strip coil and is usually spirally formed at high temperature. It is welded by double-sided submerged arc welding method and is used for pressure fluid delivery. Steel pipe can bear pressure and has good welding function. After various strict superstition tests and tests, it is safe and reliable to use. The steel pipe has large diameter, high delivery efficiency and wasteful investment in pipeline laying. Secondly, it is used to transport oil and natural gas pipelines.

5.承壓流體保送用螺旋縫高頻焊鋼管是以熱軋鋼帶卷作管坯，常常溫螺旋成型，采用高頻搭接焊法焊接的，用于承壓流體保送的螺旋縫高頻焊鋼管。鋼管承壓才能強，塑性好，便于焊接和加工成型;經過各種嚴厲和迷信檢驗和測試，運用平安牢靠，鋼管口徑大，保送效率高，并可節(jié)省鋪設管線的投資。次要用于鋪設保送石油、自然氣等的管線。

5. High frequency spiral seam welded steel pipe for pressure fluid delivery is made of hot rolled steel strip as billet, which is usually spirally formed at high temperature and welded by high frequency overlap welding method. It is used for pressure fluid delivery of spiral seam high frequency welded steel pipe. The steel pipe can bear pressure, has good plasticity, and is easy to weld and process. After various strict and superstitious tests and tests, it is safe and reliable to use, with large diameter of steel pipe, high delivery efficiency, and saves the investment of laying pipelines. Secondly, it is used to lay pipelines for guaranteeing oil, natural gas, etc.

6.普通高壓流體保送用螺旋縫高頻焊鋼管是以熱軋鋼帶卷作管坯，常常溫螺旋成型，采用高頻搭接焊法焊接用于普通高壓流體保送用螺旋縫高頻焊鋼管。

6. High-frequency spiral seam welded steel pipes for ordinary high-pressure fluid delivery are made of hot-rolled steel strips as billets, and are usually spirally formed at high temperature. High-frequency lap welding is used to weld high-frequency spiral seam welded steel pipes for ordinary high-pressure fluid delivery.

7.樁用螺旋焊縫鋼管是以熱軋鋼帶卷作管坯，常常溫螺旋成型，采用雙面埋弧焊接或高頻焊接制成的，用于土木修建構造、碼頭、橋梁等根底樁用鋼管。

7. Spiral welded steel pipe for pile is made of hot rolled steel strip coil as billet, usually formed by warm spiral, double-sided submerged arc welding or high frequency welding. It is used in civil construction, wharf, bridge and other bottom pile steel pipe.
