Imiyoboro ya ASTM A192, ASTM A179, ASTM A209, ASTM A210 y'icyuma

Umuyoboro w'icyuma udafite umugozi wa A335P92, ibisobanuro 48.3 * 7.14 (ni ukuvuga umurambararo wo hanze 48.3 mm, ubugari bw'urukuta 7.14 mm), nk'umuyoboro w'icyuma gishyushya cyane, igipimo cyo kuwushyira mu bikorwa ni ASTM A335M. Ibi bikurikira ni isesengura rirambuye ry'umuyoboro w'icyuma:

I. Incamake y'ibanze y'imiyoboro y'ibyuma
Umuyoboro w'icyuma kidahindagurika wa A335P92 ni ubwoko bw'umuyoboro w'icyuma kidahindagurika ufite ubushyuhe bwinshi n'umuvuduko mwinshi, ukoreshwa cyane mu bushyuhe bwinshi n'umuvuduko mwinshi nk'umuyoboro mukuru w'umwuka n'umuyoboro w'umwuka ushyushye wo mu nganda zitanga ingufu z'ubushyuhe. Ibikoresho byawo ni P92, ugizwe n'icyuma cya Leta Zunze Ubumwe za Amerika gifite inomero ya ASTM A335 P92 martensitic kidashyuha.

Icya kabiri, imiterere y'imiti ya Boiler y'icyuma
Imiterere y'imiyoboro y'icyuma gikozwe mu cyuma cya A335P92 igenzurwa neza, cyane cyane harimo karuboni, manganese, fosifore, sulfur, silikoni, chromium, molybdenum, vanadium, azote, nikeli, aluminiyumu, niobiyumu, tungsten na boroni n'ibindi bintu. Ingano y'ibikubiye muri iyo miyoboro ni iyi ikurikira:

Karuboni (C): 0.07~0.13%
Manganese (Mn): 0.30-0.60%
Fosifore (P): ≤0.020%
Sulfure (S): ≤0.010%
Silikoni (Si): ≤0.50%
Chromium (Cr): 8.5~9.50%
Molybdenum (Mo): 0.30~0.60% (ariko ni ngombwa kumenya ko ugereranije n'icyuma cya SA-335P91, icyuma cya SA-335P92 kigabanya neza ingano ya Mo, kandi kikanoza imikorere y'ibikoresho byongewemo ingano runaka ya W)
Vanadium (V): 0.15~0.25%
Azote (N): 0.03~0.07%
Nickel (Ni): ≤0.40%
Aluminium (Al): ≤0.04%
Niobium (Nb): ≤0.040~0.09%
Tungsten (Ubwuzure): 1.5~2.0%
Boroni (B): 0.001~0.006%

Igipimo gikwiye cy'ibi bintu gituma umuyoboro w'icyuma udafite umugozi wa A335P92 ugira ubushobozi bwo kurwanya ingese mu bushyuhe bwinshi, kurwanya ogisijeni, gukomera mu bushyuhe bwinshi no kuzamuka kw'amazi.

3. Imiterere ya tekiniki y'imiyoboro ya boiler y'icyuma
Umuyoboro w'icyuma kidakora neza wa A335P92 ufite imiterere myiza ya mekanike, igaragazwa ku buryo bukurikira:

Ingufu zo gukurura: ≥620MPa
Ingufu z'umusaruro: ≥440MP
Iyi miterere ya mekanike igenzura umutekano n'ubwirinzi bw'imiyoboro y'icyuma mu bushyuhe bwinshi n'umuvuduko mwinshi.

4. Ahantu ho gukoresha imiyoboro ya boiler y'icyuma
Umuyoboro w'icyuma udafite umugozi wa A335P92 bitewe n'imikorere yawo myiza, ukoreshwa cyane mu nzego zikurikira:

Uruganda rutanga ingufu zishyuha: nk'igikoresho cy'ingenzi cy'umuyoboro munini w'umwuka n'umuyoboro w'umwuka wongera gushyuha, rushobora kwihanganira ubushyuhe bwinshi n'umuvuduko mwinshi kugira ngo rukore neza mu mutekano uterwa n'uruvange rw'amashanyarazi.

Petrochemical: Mu gikorwa cyo gutunganya peteroli no gukora imiti, ikoreshwa mu gukora ibikoresho nka reactors, ibyuma bihindura ubushyuhe n'imiyoboro yo kohereza ibintu kugira ngo ihuze n'ibikenewe mu bushyuhe bwinshi n'umuvuduko n'ubudahangarwa bw'ingufu.

Inganda zikora ingufu za kirimbuzi: Mu nganda zikora ingufu za kirimbuzi, zikoreshwa mu gukora uburyo bwo gukonjesha imashini zikora ingufu za kirimbuzi n'imiyoboro ijyanye nazo kugira ngo habeho umutekano n'ituze mu gutanga ingufu za kirimbuzi.

5. Amabwiriza yo gushyira mu bikorwa hamwe n'amabwiriza yo gutumiza imiyoboro y'ibyuma
Umuyoboro w'icyuma gikozwe mu cyuma kidakora neza cya A335P92 wujuje ibipimo ngenderwaho bya ASTM A335/A335M. Mu gutumiza, amakuru akurikira agomba kuba asobanutse neza:

Ingano (urugero: mu birenge, metero, cyangwa imizi)

Izina ry'ibikoresho (umuyoboro w'icyuma udafite umushongi)
Icyiciro (P92)

Uburyo bwo gukora (gusoza bishyushye cyangwa gushushanya bikonje)
Ibisobanuro (urugero: umurambararo wo hanze, ubugari bw'urukuta, nibindi)
Uburebure (ingano igabanyijemo kabiri n'ingano ihindagurika)
Gusoza imashini
Ibisabwa mu guhitamo (urugero: umuvuduko w'amazi n'uburemere bwemewe)
Raporo y'ikizamini gisabwa
Nimero isanzwe
Ibisabwa byihariye cyangwa ibindi bisabwa by'inyongera

Muri make, umuyoboro w'icyuma kidahindagurika wa A335P92 ni umuyoboro w'icyuma kidahindagurika ufite ubushyuhe bwinshi n'umuvuduko mwinshi, ukoreshwa cyane mu nzego nyinshi hamwe n'imikorere myiza. Mu gutumiza no gukoresha, ni ngombwa kubahiriza neza amahame n'ibisabwa kugira ngo ugenzurwe neza kandi wizewe.

Murakaza neza kutwandikira kugira ngo mumenye byinshi!
