Tsieina Precision Dur Di-dor Tube Mecanyddol Pipe Trwch Wal Trwch Dur
Trosolwg
Rydym yn parhau i wella a pherffeithio ein nwyddau a'n gwasanaeth. Ar yr un pryd, rydym yn gwneud y gwaith yn weithredol i wneud ymchwil a gwelliant ar gyfer Pibell Dur Mecanyddol, Gyda mantais rheoli diwydiant, mae'r busnes bob amser wedi ymrwymo i gefnogi rhagolygon i ddod yn arweinydd y farchnad gyfredol yn eu diwydiannau priodol. Mae neilltuo bob amser yn sylfaenol i'n cenhadaeth. Rydym bob amser wedi bod yn unol â gwasanaethu cwsmeriaid, gan greu amcanion rheoli gwerth a chadw at y didwylledd, ymroddiad, syniad rheoli parhaus.
Cais
Fe'i Defnyddir yn Bennaf ar gyfer mecanyddol ac fe'i defnyddir i wneud silindrau nwy. Mae'n cynnwys tiwbiau mecanyddol di-dor carbon a dur aloi, ac mae'n cynnwys tiwbiau mecanyddol gorffenedig poeth di-dor a thiwbiau mecanyddol di-dor gorffenedig oer mewn meintiau hyd at a chan gynnwys 12 3⁄4 mewn. (323.8 mm) diamedr allanol ar gyfer tiwbiau crwn gyda thrwch wal yn ôl yr angen.

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 .

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.
