310S Petrochemical Cracker Castings

Dzina lazogulitsa: 310S Stainless Steel Petrochemical Cracking Furnace Castings

(Zapamwamba-Zigawo Zosagwirizana ndi Kutentha kwa Zinthu Zovuta Kwambiri)

 

 

Wopangidwa kuchokera ku aloyi ya ZG45Cr25Ni20Si2 (310S yofanana) kudzera pakuponyera mwatsatanetsatane, zigawo zathu za ng'anjo zong'ambika zimapangidwira malo owopsa mu ethylene pyrolysis ndi ntchito zoyenga. Mapangidwe awa amapereka:

Kutumikira mosalekeza mpaka 1150 digiri mu oxidizing / carburizing atmospheres

2-3x moyo wautali kuposa ma alloys a HK40 otenthetsera

Kukonzekera kwathunthu kwa ma geometries pamapangidwe apadera a riyakitala

 

 

1. Zovuta Zochita Zabwino

Carburization resistance:<0.5mm penetration after 2 years in hydrocarbon streams

Kutentha kwa kutentha: Kumalimbana ndi 50+ kuzimitsa mwachangu (madigiri 1100 →madzi)

Mphamvu zokwawa: 18MPa kupsinjika kwapakati pa digiri ya 1000 (10,000h)

 

2. Custom Engineering Solutions

Ma chubu amathandizira: Okometsedwa kuti azitha kutentha pang'ono

Zopangira ma coil: FEA-zogawa zopatsa chidwi

Zidutswa za kusintha: Malipiro okulitsa mwamakonda anu

 

3. Zowonjezera Zakuthupi

Zapamwamba-zosiyana: S/P<0.015% for reduced coking

Micro-magiredi alloyed: Zosintha za Nb/Ti zilipo

Mankhwala apamtunda: Aluminizing pofuna kukana sulfidation

 

 

Parameter	Mtengo Wokhazikika	Njira Yoyesera
Kutentha Kwambiri Kwambiri	1150 digiri (yopitilira)	Chithunzi cha ASTM E228
Mtengo wa Carburization	<0.2mm/year @950°C	Chithunzi cha ASTM G79
Mkulu{{0}Kulimba Kwakanthawi kochepa	85MPa @1000 digiri	ISO 204
Thermal Conductivity	14.5 W/m·K @800 digiri	Chithunzi cha ASTM E1225

 

 

1. Zigawo Zagawo Zowala

Ma chubu opachika ndi owongolera

Amakangana ndi burner

Zishango mbale

 

2. Magawo a Convection

Zothandizira ma chubu omalizidwa

Mgwirizano wa Damper

Sootblower zigawo

 

3. Ntchito Zapadera

Kusamutsa zigongono

Olekanitsa mphepo yamkuntho

Kukongoletsa mafelemu a zitseko

 

 

Pa{{0}zotsimikizira za oponya:

Chemical Analysis (OES)

Kuyeza-kutentha kwambiri

Kufufuza kwa Microstructure (ASTM E3)

 

Dimensional control:

Kusanthula kwa laser kuti mutsimikizire ma contour

Wall makulidwe a UT mapu

 

Zitsimikizo:

ASME Gawo VIII Div.1

NACE MR0175/MR0103

API 530 kutsatira

 

 

Ndemanga ya Ntchito

Kusanthula kapangidwe ka gasi

Mapu a mbiri yotentha

Gawo la Engineering

Kuwerengera moyo wa Creep pa API 530

Matenthedwe kukulitsa chitsanzo

Kupanga

 

Nthawi Yotsogolera: Masabata a 10-14 pazojambula zachizolowezi

Kutumiza mwachangu (+30% chindapusa)

 

Phukusi Lotumiza

Malipoti oyesera zinthu (EN 10204 3.2)

Kuyika zojambula ndi deta ya kukula kwa kutentha

Ndondomeko yokonza yovomerezeka

 

 

Ethylene Crackers: USC/UHP ng'anjo yamoto

Ochedwa Cokers: Fractionator internals

Zomera za haidrojeni: Zigawo zoyambirira zosinthira

Zowonjezera Zotsalira: Zida za FCC reactor

 

 

Mbiri yotsimikizirika: 500+ kubwezeredwa kwa ng'anjo kuyambira 2010

 

Othandizira ukadaulo:

Kasamalidwe ka zinthu zotsalira

Ntchito zotsalira zowunika moyo

 

Ziphaso zapadziko lonse lapansi:

PED 2014/68/EU

ABS / CE yovomerezeka kuti igwiritsidwe ntchito kunyanja

 

Chidziwitso: Funsani za Cracking Furnace Component Life Extension Programme kuphatikiza:

Mu{{0}malangizo oyendera ntchito

Field metallurgical replication services

Kupanga alloy mwamakonda pazakudya zapadera
