選購不銹鋼管時(shí)該注意哪些細節

發(fā)布時(shí)間:2017-01-10 瀏覽:724

  1、表面光潔,外焊縫打磨細膩


  不銹鋼管表面無(wú)砂孔、壓點(diǎn)、咬邊、線(xiàn)性拉傷等缺陷,外焊縫打磨細膩,適合拋精光、鏡光、電鍍等。


  2、焊接平整,適合裝配。


  焊接電流和焊接速度嚴格按制品管的工藝流程操作,內焊縫平整,沒(méi)有明顯的溝槽或外凸出,沒(méi)有黑線(xiàn)和明顯的手感。


  3、尺寸精準,易切割,攻牙,抽心彎等等


  產(chǎn)品規格:外徑:5mm-63mm壁厚:0.26mm-2.0mm。產(chǎn)品通過(guò)化驗分析、機械及工藝性能測定、腐蝕、水壓試驗等各類(lèi)測試,尺度精準(圓度誤差+/-0.05mm,厚度誤差+/-0.02mm),性能優(yōu)良。


  4、性能優(yōu)良,容易折彎


  用延伸率好的材料,加上焊接牢靠,在標準規定的范圍內使用,擴口、折彎、錐管不開(kāi)裂。


  5、耐腐蝕不易生銹,質(zhì)量可靠
