Pìoba stàilinn carbon agus pìob stàilinn alloy
Tha a’ chompanaidh againn an sàs ann an gnìomhachas às-mhalairt de stàilinn gualain agus stàilinn alloy.Pìob Alloy, pìob stàilinn alloy, Alloy Steel Pìoba Sìona, pìob gualain, Pìoba Stàilinn Carbon, Pìoba stàilinn carbon Sìona.
A bheil fios agad air an eadar-dhealachadh eadar stàilinn gualain agus stàilinn alloy?
Stàilinn gualain:sa mhòr-chuid a’ toirt iomradh air na feartan meacanaigeach an urra ri susbaint gualain stàilinn, agus sa chumantas na cuir a-steach mòran eileamaidean alloying de stàilinn, ris an canar uaireannan stàilinn gualain sìmplidh no stàilinn gualain. Carbon stàilinn, ris an canar cuideachd carbon stàilinn, carbon susbaint WC nas lugha na 2% iarann carbon alloy.
A bharrachd air an sin sa chumantas tha ìre bheag de silicon, manganese, sulbhur, fosfar ann an stàilinn gualain a roinn a rèir cleachdadh stàilinn gualain structarail gualain, stàilinn inneal gualain agus stàilinn structarail gearradh an-asgaidh tha trì stàilinn structarail gualain air a roinn ann an stàilinn structarail agus stàilinn structarail inneal, a dh'fhaodar a roinn ann an stàilinn gualain ìosal (WC ≤ 0.25%), stàilinn meadhanach gualain (WC 0.25% - 0.6%) agus steels gualain àrd (WC> 0.6%).
A rèir susbaint fosfair agus sulbhur, faodar steels gualain a roinn ann an steels gualain àbhaisteach (tha fosfar agus sulbhur nas àirde), steels gualain àrd-inbhe (tha fosfar agus sulbhur nas ìsle) stàilinn àrd-inbhe (fosfair, sulbhur nas ìsle).
Alloy stàilinn:stèidhichte air stàilinn gualain, tha aon no barrachd eileamaidean alloying air an cur a dh’aona ghnothach gus piseach a thoirt air comas seirbheis agus coileanadh pròiseas an alloy stèidhichte air iarann ris an canar stàilinn alloy. Tha stàilinn alloy a ’toirt iomradh air an stàilinn anns a bheil silicon agus manganese mar eileamaidean alloying no eileamaidean deoxidizing, eileamaidean alloying eile leithid chromium, nicil, molybdenum, vanadium, titanium, copar, tungsten, alùmanum, cobalt, niobium, zirconium agus eileamaidean eile, agus cuid cuideachd tha cuid de eileamaidean neo-mheatailt (leithid boron, nitrigin, msaa) stàilinn.
A rèir an àireamh de alloying eileamaidean ann an stàilinn, ach cuideachd faodar a roinn ann an ìosal alloy stàilinn, meadhanach alloy agus àrd alloy stàilinn.
Eadar-dhealachadh ann an co-dhèanamh ceimigeach:
(1) Carbon stàilinn: Ìosal carbon stàilinn (C≤0.25%); Stàilinn carbon meadhanach (C≤0.25 ~ 0.60%); Àrd carbon stàilinn (C≤0.60%).
(2) Alloy stàilinn: Ìosal alloy stàilinn (iomlan susbaint alloying eileamaidean ≤ 5%); Stàilinn alloy meadhanach (susbaint iomlan nan eileamaidean alloying> 5 ~ 10%); Stàilinn àrd alloy (susbaint iomlan nan eileamaidean alloying> 10%.
Buannachdan stàilinn carbon:
Tha neart àrd, ductility agus cruas, cosgais ìosal, air a chleachdadh ann an innealan trom airson pàirtean luchdan troma a dhèanamh. Faodar fhaighinn le làimhseachadh teas feartan meacanaigeach nas fheàrr air an tilgeadh.
Buannachdan stàilinn alloy:
A bharrachd air iarann ann an stàilinn eileamaidean anns a bheil a-mhàin carbon stàilinn, carbon stàilinn, eile sileaconach, sulbhur, phosphorus agus neo-dhìomhaireachd eile. A bharrachd air eileamaidean eile de chromium, manganese, molybdenum, titanium, tungsten, vanadium, niobium, boron, silicon agus nicil alloy stàilinn gus na feartan a tha a dhìth leithid teòthachd àrd, àrd elasticity, strì an aghaidh sgrìobadh, neart àrd, cruas àrd agus mar sin a choileanadh air adhart. Tha cruas stàilinn alloy an aghaidh caitheamh, cruasachd, strì an aghaidh creimeadh na stàilinn gualain sàr-mhath.

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.
