meud nas cudromaiche, an uairsin bu chòir tuban fuar-obrach a bhith air a shònrachadh don taobh a-staigh trast-thomhas agus tighead balla no taobh a-muigh trast-thomhas agus trast-thomhas a-staigh.
Tubing meacanaigeach air a thionndadh - Cha bhith atharrachadh ann an trast-thomhas taobh a-muigh agus tighead balla nas àirde na an fhulangas sa chlàr. Tha an clàr a’ còmhdach fulangas mar a thèid a chuir an sàs ann an trast-thomhas a-muigh agus tighead balla agus a’ buntainn ris a’ mheud ainmichte.
Tubing meacanaigeach talmhainn - Cha bhith atharrachadh ann an diam-eter taobh a-muigh nas àirde na na fulangas sa chlàr. Mar as trice bidh an toradh seo air a thoirt a-mach à tiùb fuar-obrach.
Faid - Mar as trice bidh tubing meacanaigeach air a thoirt seachad ann am faid muilne, 5 tr (1.5 m) agus nas sine. Tha faid gearraidh cinnteach air a thoirt seachad nuair a thèid a shònrachadh leis a’ cheannaiche. Tha fulangas fad air a shealltainn ann an Clàr .
Straightness - Cha bhith na fulangas dìreach airson tubing cruinn fuaigheil nas àirde na na suimean a chithear sa chlàr.
Riatanas deuchainn
1.Hardness Test
Nuair a tha feum air crìochan cruas, thèid co-chomhairle a chumail ris an neach-dèanamh. Tha cruas àbhaisteach air a liostadh ann an Clàr . Nuair a thèid a shònrachadh, thèid an deuchainn cruas a dhèanamh air 1% de na tiùban.
Deuchainnean 2.Tension
Nuair a tha feum air feartan tensile, thèid co-chomhairle a chumail ris an neach-dèanamh. Tha feartan tensile àbhaisteach airson cuid de na h-ìrean as cumanta agus suidheachaidhean teirmeach air an liostadh sa chlàr.
Deuchainnean 3.Nondestructive
Tha diofar sheòrsaichean de dheuchainnean ultrasonic no electromagnetic nondestructive rim faighinn. Thèid an deuchainn a thèid a chleachdadh agus na crìochan sgrùdaidh a stèidheachadh le aonta neach-dèanamh agus ceannaiche.
4.Flaring Test
Nuair a tha riatanasan sònraichte ann airson glainead stàilinn, thèid na dòighean deuchainn agus crìochan gabhail a stèidheachadh le aonta neach-dèanamh agus ceannaiche.
