ASTM A252: Sònrachadh Coitcheann airson Pìoban Pìoba Stàilinn Tàthaichte agus Gun ròin.
Tha an sònrachadh seo a’ còmhdach pileachan pìoba stàilinn balla ainmichte (cuibheasach) de chumadh siolandair agus a’ buntainn ri pileachan pìoba anns a bheil an siolandair stàilinn ag obair mar bhall giùlan luchdan maireannach, no mar shlige gus pileachan cruadhtan tilgeadh a chruthachadh.Thathas a’ toirt a-mach pileachan pìoba an dà chuid mar thoraidhean tàthaichte agus fuaigheil.
Putanan seòlaidh
Ìre ASTM A252
Tha ìrean ASTM A252 air an seòrsachadh mar Ìre 1 Ìre 2 agusÌre 3.
Pròiseas Riochdachaidh Stuth Raw
Thèid an stàilinn a dhèanamh le aon no barrachd de na pròiseasan a leanas: cagailt fosgailte, ocsaidean bunaiteach, no fùirneis dealain.
Stuthan agus Dèanamh
Bidh pileachan air an dèanamh leis a’ phròiseas fuaigheil, strì an aghaidh dealain, tàthadh flash, no tàthadh fusion.
Feumaidh na claisean de phìoban tàthaichte a bhith fada, cnap-starra no uchd helical.
Co-dhèanamh ceimigeach ASTM A252
Modh deuchainneach: ASTM A751.
Cha bu chòir barrachd air 0.050% fosfair a bhith anns an stàilinn.Tha seo air sgàth gum faodadh ìrean àrda fosfair adhbhrachadh gu bheil stàilinn a’ fàs brònach aig teòthachd ìosal, a’ lughdachadh cruas an stuth.
Tha riatanasan cuibhrichte aig sònrachadh ASTM A252 airson co-dhèanamh ceimigeach: tha seo air sgàth gu bheil ASTM A252 a’ buntainn gu sònraichte ri tagraidhean structarail, gu sònraichte mar eileamaidean giùlan luchd, far a bheil feartan fiosaigeach (leithid neart toraidh, neart tensile, agus leudachadh) nas cudromaiche na co-dhèanamh ceimigeach. .Faodar na feartan fiosaigeach sin a choileanadh tro phròiseasan saothrachaidh ceart agus làimhseachadh teas gun smachd teann air co-dhèanamh ceimigeach a bharrachd air fosfar.
Riatanasan tensile ASTM A252
Modh deuchainneach: ASTM A370.
Deuchainn Brùthadh Hydrostatic
Is e an adhbhar nach eil ASTM A52 a’ sònrachadh deuchainn uisgeachaidh gu sònraichte mar thoradh air feartan tagraidh agus riatanasan dealbhaidh nam pìoban sin.
Airson pileachan pìoba stàilinn ann an sònrachadh ASTM A252, is e am prìomh adhbhar dealbhaidh seasamh ri luchdan aiseach, chan e cuideaman a-staigh.Tha seo an taca ri pìobaireachd airson lioftaichean no gasaichean a ghiùlan, leithid an fheadhainn a tha fo shònrachadh API 5L, a dh’ fheumas a bhith fo dheuchainn dìreach air cuideam a-staigh gus dèanamh cinnteach gu bheil e teann agus neart.

Duilgheadasan uachdar pìoba
1. Gabhar ri neo-fhoirfeachdan uachdar le doimhneachd nach eil nas motha na 12.5% de thighead ainmichte a’ bhalla.
Bidh e ceadaichte doimhneachd nan neo-fhoirfeachdan sin a stèidheachadh le bhith a’ bleith no a’ sìoladh.
2. Bithear a’ beachdachadh air neo-fhoirfeachdan uachdar le doimhneachd nas motha na 12.5% de thighead ainmichte a’ bhalla mar lochdan.
Bidh e ceadaichte uireasbhaidhean nach eil nas doimhne na 33.3% den tighead balla ainmichte a bhith air an càradh le tàthadh, fhad ‘s a thèid an locht a thoirt air falbh gu tur mus tèid an tàthadh.
