          煤礦用瓦斯管抽放管

          不銹鋼壓型(咬合)加強筋螺旋焊接瓦斯抽放管
          不銹鋼壓型(咬合)加強筋螺旋焊接瓦斯抽放管

          一、不銹鋼咬合加強筋螺旋焊管

          產品介紹:

                不銹鋼咬合加強筋螺旋焊管是以一種以不銹鋼鋼帶為原材料,通過專用咬合成型設備螺旋折疊咬合焊接制成,管徑為1591200mm,厚度為1.03mm的新型管材,咬合形式為外咬合,成型后內壁平滑無槽,接縫處四層帶鋼通過咬合形成螺旋狀加強筋,自由端筋側用無飛濺的氬弧焊工藝進行滿焊,形成45度角焊縫,保證了瓦斯抽采高效安全,管道具有重量輕、強度高、摩擦系數小、連接簡單等優勢,。

          執行標準:

                GB/T12771-2008 MT181-1988

          應用范圍:

                煤礦井下用抽放瓦斯。

          產品特點:

          1.管材采用加強筋結構,由四倍壁厚咬合而成的實體加強筋,增強了管材的強度,提高了管材的環剛度和抗壓能力,可以大大地降低管材的壁厚,從而降低管材的造價;

          2. 管道的內壁平整光滑,沒有溝槽,避免了煤粉及有機塵粒的沉積,降低了靜電產生的可能,有效減少了安全隱患;

          3. 徹底解決了煤礦井下瓦斯管道的抗靜電、阻燃的性能,瓦斯輸送時安全保障度高;

          4. 管材的特殊性:管材成型過程中獨特的咬合結構,使得該管材在煤礦瓦斯輸送過程中,因地質變化,產生的位移或拉伸,咬合部分通過延伸而釋放3%-6%的長度,同時又確保瓦斯氣體不泄露。這是其它普通金屬管材都不具備的特性。

          5.304奧氏體型不銹鋼耐腐蝕性能好,不生銹、不需要做專門的防腐處理,屈服強度高,韌性好,抗打擊、碰撞、擠壓的性能強,可使正常使用壽命達到30年以上,降低了瓦斯管道的維護和更換費用。

          6.管材重量輕、運輸方便、僅為普通鋼管重量的1/4-1/3,方便煤礦井下運輸和安裝,安裝費用低。

           



          二、不銹鋼壓型加強筋螺旋焊管

          產品介紹:

                不銹鋼壓型加強筋螺旋焊管,是一種以不銹鋼鋼帶為原材料,通過專用設備壓筋焊接而成的管徑為2731200mm,厚度為1.53mm的新型管材,管材表面具有螺旋加強筋結構,大大提高了管材的強度。  管材具有的特殊焊縫結構,起到密封及加強筋的作用,同時提高了管材的抗負壓強度;采用不銹鋼材料,提高了管道壽命,同時具有抗靜電效果;該管道安全性能高,生產成本和安裝成本低,比相同規格管材重量輕60% 

          執行標準:

                GB/T12771-2008 MT181-1988

          應用范圍:

                煤礦井下用抽放瓦斯。 

          產品優點:

          1、國內領先的加工工藝提高了產品檔次,提高了產品性價比。原料采用優于國標的不銹鋼帶,

          管材生產采用我公司自主研發工藝、采用世界先進的不銹鋼焊接技術和完全自動化的法蘭焊

          接技術。先進技術的應用,使產品更加安全可靠。

          2、耐腐蝕性好。304奧氏體型不銹鋼具有優異的耐腐蝕性能,不生銹、不需要做專門的防腐處

          理,可以用在煤炭行業的酸性氣體排放,具有極高的化學穩定性。

          3、管材結構設計合理,采用壓型加強筋后,管材自身強度提高5倍,也就是在保證安全強度的

          前提下,管材厚度可以降低4/5

          4、重量輕,安裝方便。重量可以降低到其他實壁瓦斯管材的1/4--1/3以上,是目前最輕便的

          瓦斯抽放管材。

          5、安裝費用低,安裝效率高。安裝人工費要比鋼管安裝人工費節約一半以上,安裝進度提高一

          倍。

          6、使用壽命長。既有塑料管道的高耐腐蝕性能,又有鋼制管道的高耐壓強度,韌性好、抗擊打、碰撞、擠壓性能優異,是集鋼塑優越性能于一體的新型管材,使用壽命可達30年以上。
          7、連接簡單:采用兩頭法蘭連接,連接簡單,安裝方便。

          產品的缺點

                不銹鋼類產品較其他類瓦斯管道綜合成本較高。
