    yn ddimensiwn pwysicach, yna dylid pennu tiwbiau oer i ddiamedr y tu mewn a thrwch wal neu ddiamedr allanol a diamedr y tu mewn.
    Tiwbiau Mecanyddol wedi'u Troi'n Arw - Ni fydd yr amrywiad mewn diamedr allanol a thrwch wal yn fwy na'r goddefiant yn y Tabl. Mae'r tabl yn cwmpasu goddefiannau fel y'i cymhwysir i ddiamedr allanol a thrwch wal ac yn berthnasol i'r maint penodedig.
    Tiwbiau Mecanyddol Daear - Ni ddylai amrywiad mewn diamedr allanol fod yn fwy na'r goddefiannau yn y Tabl. Mae'r cynnyrch hwn fel arfer yn cael ei gynhyrchu o diwb sy'n gweithio'n oer.
    Hyd - Mae tiwbiau mecanyddol yn cael eu dodrefnu'n gyffredin mewn hyd melin, 5 troedfedd (1.5 m) a throsodd. Mae darnau toriad pendant yn cael eu dodrefnu pan nodir hynny gan y prynwr. Dangosir goddefiannau hyd yn Nhabl .
    Sythrwydd - Ni ddylai'r goddefiannau sythrwydd ar gyfer tiwbiau crwn di-dor fod yn fwy na'r symiau a ddangosir yn y Tabl.

     

    Gofyniad Prawf

    Prawf 1.Hardness
    Pan fydd angen terfynau caledwch, dylid ymgynghori â'r gwneuthurwr. Rhestrir caledwch nodweddiadol yn Nhabl . Pan nodir hynny, rhaid cynnal y prawf caledwch ar 1% o'r tiwbiau.

    Profion 2.Tension
    Pan fydd angen priodweddau tynnol, dylid ymgynghori â'r gwneuthurwr. Mae priodweddau tynnol nodweddiadol ar gyfer rhai o'r graddau ac amodau thermol mwy cyffredin wedi'u rhestru yn y tabl.

    Profion 3.Nondestructive
    Mae gwahanol fathau o brofion ultrasonic neu electromagnetig nad ydynt yn ddinistriol ar gael. Rhaid sefydlu'r prawf i'w ddefnyddio a'r terfynau arolygu trwy gytundeb y gwneuthurwr a'r prynwr.

    Prawf 4.Flaring
    Pan fo gofynion arbennig ar gyfer glendid dur, rhaid sefydlu'r dulliau prawf a therfynau derbyn trwy gytundeb y gwneuthurwr a'r prynwr.
