I-Tungsten Carbide Thread Nozzle ye-Petroleum & Chemical Industry

Isingeniso  

Ezimbonini ze-petroleum namakhemikhali, ukuqina kwemishini ngaphansi kwezimo ezimbi kakhulu—njengokugeleza koketshezi olunomfutho ophezulu, izinhlayiya ezilimazayo, nezindawo ezibolayo—kubalulekile. Imibhobho yentambo ye-Tungsten carbide (WC) ivele njengesixazululo esiphezulu, enikeza ukumelana nokugqokwa okungenakuqhathaniswa, ukumelana nokugqwala, namandla emishini uma kuqhathaniswa nezinto zendabuko ezifana nensimbi engagqwali noma izitsha zobumba. Lesi sihloko sihlola ukwakheka, izinzuzo, ukukhiqizwa, kanye nokusetshenziswa kwemibhobho yentambo ye-tungsten carbide emikhakheni kawoyela, igesi, namakhemikhali.  

 1. Iyini i-Tungsten Carbide Thread Nozzle?  

I-thread nozzle iyisakhi esakhiwe ngokunemba esisetshenziswa kumasistimu okulawula uketshezi ukuze kulawule indlela ukugeleza ngayo, ingcindezi, kanye nesivinini. Uma akhiwe nge-tungsten carbide, la mabhomu abonisa ubulukhuni obukhethekile (1,400–2,200 HV) nokuqina, okuwenza alungele izindawo zezimboni ezinokhahlo.  

 Izici Eziyinhloko:  

✔ I-Ultra-High Wear Resistance – Imelana nezinhlayiya ezilumayo odakeni lokumba noketshezi olugcwele isihlabathi.  

✔ I-Corrosion Resistance - Isebenza nge-acidic (H₂S/CO₂) nezimo ze-alkaline.  

✔ Ukuzinza Kwezinga Lokushisa Okuphezulu - Igcina ubuqotho besakhiwo kufika ku-1,000°C.  

✔ Idizayini Enemicu - Iqinisekisa ukufakwa okuphephile kumapayipi anengcindezi ephezulu.  

 2. Izicelo kuPetroleum & Chemical Industries

 2.2 Ukucwenga & Ukucutshungulwa kwe-Petrochemical  

- Imilomo Yomjovo Ye-Catalyst: Ivimbela ukugqokwa kwamayunithi e-FCC (Fluid Catalytic Cracking).  

- I-Desulfurization Spray Nozzles: Imelana nokuchayeka kwe-sulfuric acid.  

 2.3 Izimboni Zamakhemikhali Namandla  

- Ama-Nozzles Okuhlanza Amandla Kakhulu: Asetshenziswa ekuhlanzeni amashubhu kabhayela.  

- I-Corrosive Fluid Disspersion: Imelana nokuhlaselwa kwamakhemikhali ezinhlelweni zokudlulisa i-asidi/alkali.  

3. Kungani i-Tungsten Carbide Idlula Izinto Zendabuko?  

I-Property Tungsten Carbide Stainless Steel (316L) Ceramic (Al₂O₃)

Ukuqina (HV) 1,400–2,200 200–300 1,500–1,800

Impact Resistance High Mederate Low (Brittle)

I-Corrosion Resistance Kuhle kakhulu (WC-Ni) Okumaphakathi (Pitting) Kubi (HF/NaOH)

Izinga Lokushisa Eliphezulu (°C) 1,000 800 1,600 (I-Thermal-takene ukushaqeka)

Izinzuzo:  

- 5–10x ubude besikhathi sokuphila kunamabhomu ensimbi ezimeni zokuhuzuka.  

- Yehlisa isikhathi sokuphumula ngokunciphisa ukushintshwa kwemibhobho.  

- Ukunemba kokugeleza okuphezulu ngenxa yokuguquguquka okuncane okubangelwa ukuguguleka.  

4. Inqubo Yokukhiqiza Ye-WC Thread Nozzles  

 4.1 I-Powder Metallurgy  

1. Ukuxuba Impushana: I-WC powder + Co/Ni binder (6-12%).  

2. Ukucindezela: Ukucindezela okubandayo kwe-isostatic (CIP) kokuminyana okufanayo.  

3. I-Sintering: I-vacuum sintering ku-1,400–1,500°C ukuze kuhlanganiswe ngokugcwele.  

 4.2 Ukukhanda nokuhlanganisa  

- Ukugaya: Ukugaya isondo ledayimane lokubekezelela ukunemba (± 0.01mm).  

- Ukusika Intambo: Imishini ye-CNC yezintambo ezihambisana ne-API/ISO.  

 4.3 Ukulawulwa Kwekhwalithi  

- Ukuhlolwa kwe-Ultrasonic: Ithola imifantu yangaphakathi.  

- Ukuhlolwa Kobukhulu: Ukuqinisekiswa kwe-CMM (Coordinate Measuring Machine).  

- Ukuhlola Ukuqina Nokuqina: Kuqinisekisa ≥99.5% ukuminyana kwethiyori.  

5. Isibonelo: I-WC Nozzle in Offshore Drilling  

Inkinga: Umsebenzisi we-North Sea ubhekane nokuhluleka komlomo wombhobho kaningi ngenxa yokuguguleka kwesihlabathi (ukushintsha njalo emavikini ama-2).  

Isixazululo: Kushintshelwe ku-WC-13Co imibhobho yochungechunge.  

Umphumela:  

✔ Impilo yesevisi inwetshiwe ibe yizinyanga ezingu-6+  

✔ Kwehliswe izindleko zokulungisa ngo-70%
