mso-hansi-font-family:"Times New Roman"">四、金屬導(dǎo)管量規(guī)使用方法：

1、檢測導(dǎo)管最大外徑：試樣長度依據(jù)標(biāo)準(zhǔn)要求，選擇《GBT17194-2導(dǎo)管最大外徑的環(huán)規(guī)》無需過分用力便能使環(huán)規(guī)通過整段導(dǎo)管試樣時，該導(dǎo)管試樣為合格。正常情況下，有保護(hù)性涂鍍層的導(dǎo)管應(yīng)在涂鍍前進(jìn)行此項試驗。

2、檢測金屬剛性導(dǎo)管最小外徑：試樣長度依據(jù)標(biāo)準(zhǔn)要求，選擇《GBT17194-3a剛性金屬導(dǎo)管最小外徑量規(guī)》不過分用力，量規(guī)就不可能通過整段導(dǎo)管時，該導(dǎo)管試樣為合格。

3、檢測非金屬剛性導(dǎo)管最小外徑：試樣長度依據(jù)標(biāo)準(zhǔn)要求，選擇《GBT17194-3b非剛性金屬導(dǎo)管最小外徑量規(guī)》在自重作用下，環(huán)規(guī)不能通過整段導(dǎo)管時，該導(dǎo)管試樣為合格。

4、檢測導(dǎo)管與配件的外螺紋：試樣長度依據(jù)標(biāo)準(zhǔn)要求，選擇《GBT17194-4外螺紋通(T)/ mso-hansi-font-family:"Times New Roman"">止(Z) "Times New Roman"">環(huán)規(guī)》，無需過分用力便可把螺紋環(huán)規(guī)(T) "Times New Roman"">旋入導(dǎo)管的螺紋中；而不過分用力，就無法使螺紋環(huán)規(guī)(Z) "Times New Roman"">通過螺紋，則該導(dǎo)管試樣的外螺紋為合格。

5、檢測導(dǎo)管與配件的內(nèi)螺紋：試樣長度依據(jù)標(biāo)準(zhǔn)要求，選擇《GBT17194-5內(nèi)螺紋通(T)/ mso-hansi-font-family:"Times New Roman"">止(Z) "Times New Roman"">塞規(guī)》，無需過分用力便可把螺紋塞規(guī)(T) "Times New Roman"">旋入導(dǎo)管的螺紋中去；而不過分用力就無法使螺紋塞規(guī)(Z) "Times New Roman"">通過螺紋，該配件試樣的內(nèi)螺紋為合格。

mso-hansi-font-family:"Times New Roman"">五、金屬導(dǎo)管量規(guī)設(shè)備保養(yǎng)及維護(hù)：
