外加厚石油油管螺紋環(huán)塞規(guī)分外加厚石油油管螺紋塞規(guī)(栓規(guī)),外加厚石油油管螺紋環(huán)規(guī)。用于檢測(cè)美國(guó)石油協(xié)會(huì)(API)標(biāo)準(zhǔn)的內(nèi)外螺紋。 1.050TGB-41/2TBG(不加厚油管螺紋環(huán)塞規(guī)),1.050UPTBG-41/2UPTBG(為外加厚油管螺紋環(huán)塞規(guī)),螺紋為60°牙形角,1:16的錐度。石油管螺紋量規(guī)特點(diǎn)在于:獨(dú)霸塞規(guī)和環(huán)規(guī)的螺紋單項(xiàng)要素(錐度,螺距,半角和塞規(guī)中徑);用校訂塞規(guī)作為磨練基準(zhǔn),與它配對(duì)的校訂環(huán)規(guī)作為傳遞基準(zhǔn),把校訂環(huán)規(guī)與校訂塞規(guī)的配對(duì)慎密距,傳遞給工作規(guī)獲得交換慎密距,再傳遞給產(chǎn)物螺紋。
石油油管螺紋塞環(huán)規(guī)精包裝,包裝前經(jīng)過防潮防銹處理.里面附加產(chǎn)品合格證,標(biāo)明產(chǎn)品出廠日期。檢驗(yàn)效果出色,精密度高.
