  今天山東無縫鋼管廠來和大家說說無縫鋼管的制造工藝與實際用途。

  Shandong seamless steel pipe seamless steel pipe to and you talk about today's manufacturing process and the actual use.

  無縫鋼管是一種具有中空截面、周邊沒有接縫的長條鋼材。鋼管具有中空截面，大量用作輸送流體的管道，如輸送石油、天然氣、煤氣、水及某些固體物料的管道等。

  Seamless steel pipe is a hollow section, no seams around the strip steel.Steel pipe has a hollow section, a large number of used for conveying fluid pipe, such as oil, natural gas, coal gas, water and some solid materials, such as pipelines.

  鋼管與圓鋼等實心鋼材相比，在抗彎抗扭強度相同時，重量較輕，是一種經濟截面鋼材，廣泛用于制造結構件和機械零件，如石油鉆桿、汽車傳動軸、自行車架以及建筑施工中用的鋼腳手架等。

  Compared to the steel pipe and round steel solid steel bending torsional strength phase at the same time, the weight is lighter, is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts, such as petroleum drill pipe, auto transmission shaft, bicycle frame and construction of steel scaffolding is used.

  用鋼管制造環形零件，可提高材料利用率，簡化制造工序，節約材料和加工工時，如滾動軸承套圈、千斤頂套等，目前已廣泛用鋼管來制造。

  With steel pipe manufacturing annular parts, can improve material utilization, simplifying the manufacturing process, material saving and processing time, such as rolling bearing ring, jack sets, at present has been widely made from steel pipe.

  無縫鋼管的制造工藝

  Seamless steel tube manufacturing process

  1.熱軋（擠壓無縫鋼管）：圓管坯→加熱→穿孔→三輥斜軋、連軋或擠壓→脫管→定徑（或減徑）→冷卻→矯直→水壓試驗（或探傷）→標記→入庫

  1. Hot extrusion (seamless steel tube) : the circular tube billet - heat - punch - three-roll skew rolling, rolling, or pressing - to take off the tube and sizing (or reducing) - cooling - straightening to hydrostatic test or inspection - > tag, put in storage

  2.冷拔（軋）無縫鋼管：圓管坯→加熱→穿孔→打頭→退火→酸洗→涂油（鍍銅）→多道次冷拔（冷軋）→坯管→熱處理→矯直→水壓試驗（探傷）→標記→入庫

  2. Cold drawing (rolling) seamless steel pipe: the circular tube billet - heat - punch to heading, annealing and pickling to apply oil (copper), multi-channel time cold drawing (cold) and billet tube - heat treatment - straightening to hydrostatic test (NDT) - > tag, put in storage
