5. Manufacturing Process

1. Raw Material: Certified steel billets kubva mudzimba uye pasi rose zvigayo

2. Kutenderedza Kupisa: Mabhiriji akadziya kusvika 1150–1200°C, akaboorwa uye akakungurutswa nokuda kwechubhu hombe-dhayamita kana gobvu-madziro.

3. Cold Drawing: Multiple-pass inotonhora kudhirowa kweiyo chaiyo saizi uye pamusoro pekupedzisira

4. Kurapa Kupisa: Solution annealing pa980–1150°C, kukurumidza kudzima mvura kudzvanyirira kunaya kwecarbide.

5. Welding: GTAW (TIG), PAW, uye SAW maitiro, achishandisa ER347 filler wire yekudzikamisa; back purging options dziripo

6. Surface Pedzisa: Pickling, passivation (HNO₃/HF), uye mechanical polishing (Ra ≤ 0.2µm pakukumbira)

7. Kuongorora: 100% RT (radiographic test) ye welds; ultrasonic, hydrostatic, PMI, intergranular corrosion test sezvinodiwa

6. Certification & Quality Control

Womic Simbi's 347H Stainless simbi mapaipi anosimbiswa pasi:

- ISO 9001:2015

- Corrosion bvunzo (IGC paASTM A262)

-Kusina-kuparadza kuyedzwa (UT, RT, Eddy ikozvino)

- Dimensional yekuongorora uye yakazara traceability

7. Minda Yekushandisa

347H Stainless simbi pombi inoshandiswa zvakanyanya mu:

-Simba Generation: Superheaters, reheaters, main steam pombi mune subcritical uye supercritical thermal magetsi zvidyarwa.

- Solar Thermal Energy: Akanyungudutswa emunyu ekuchengetera matangi (450-565 ° C), akabvumikiswa kushandiswa mumapurojekiti muChina (Yumen, Haixi)

- Petrochemical: Furnace tubes, hydroprocessing reactors (inopesana neH₂-H₂S-H₂O nharaunda)

- Aerospace: Injini inopedza ducts uye turbine mhepo yekupa pombi (inoshanda kusvika 850 ° C)

- Heat Exchangers: Yepamusoro-tembiricha condensers uye pombi mune yekunatsa uye marine masisitimu

8. Kugadzira Nguva Yekutungamira

- Seamless Tubes (Standard Size): 15-25 mazuva

- Custom Dimensions / Makobvu Wall Mapaipi: 30-45 mazuva

-Mahombe-Makuro maOdha: Kugona kweanopfuura zviuru zvitatu zvematani / mwedzi kunovimbisa kukurumidza kutumirwa kunyangwe pasi pekukurumidzira nguva.

9. Packaging & Logistics

Womic Steel inopa yakachengeteka uye inogoneka kurongedza:
