Ro-shealladh
Bidh sinn a’ cumail a’ leasachadh agus a’ dèanamh foirfeachd air ar bathar agus ar seirbheis. Aig an aon àm, bidh sinn a 'dèanamh an obair gu gnìomhach gus rannsachadh agus leasachadh a dhèanamh airson Pìoba Stàilinn Meacanaigeach, Le buannachd bho stiùireadh gnìomhachais, tha an gnìomhachas air a bhith dealasach a-riamh a bhith a' toirt taic do chothroman gus a bhith na stiùiriche margaidh làithreach anns na gnìomhachasan aca fhèin. Tha tiomnadh an-còmhnaidh bunaiteach don mhisean againn. Tha sinn an-còmhnaidh air a bhith a rèir a bhith a 'frithealadh luchd-cleachdaidh, a' cruthachadh amasan stiùireadh luach agus a 'cumail ris a' bheachd-smuaintean stiùiridh, dìcheallach, leantainneach.
Iarrtas
Tha e air a chleachdadh sa mhòr-chuid airson siolandairean meacanaigeach agus air a chleachdadh airson siolandairean gas a dhèanamh. (323.8 mm) trast-thomhas taobh a-muigh airson tiùban cruinn le tiugh balla mar a dh ’fheumar.

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 .

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.
