ʻO Womic Steel - Hana Kiʻekiʻe 347H Kūleʻa Kūleʻa Pipe

1. Nānā Mea

ʻO 347H paipu kila kila he kiʻekiʻe-carbon niobium-stabilized austenitic stainless steel i ʻike ʻia no kona ikaika kiʻekiʻe kiʻekiʻe, weldability maikaʻi loa, a me ke kūʻē kūʻē i ka intergranular corrosion. ʻO ka hoʻohui ʻana o ka niobium (Nb) e hoʻomaikaʻi i ka ikaika creep a pale i ka chromium carbide precipitation ma nā palena o ka palaoa, e hōʻoiaʻiʻo ana i ka hoʻoikaika ʻana i ke kūpaʻa ʻana i ka sensitization.

2.Hoʻohui Kimia (Maʻamau)

3. Mea Mechanical & Corrosion

Nā Pono Mechanical (ASTM A213):

- Ka ikaika uʻi ≥ 515 MPa

- Ka ikaika hua ≥ 205 MPa

- Elongation ≥ 35%

- Ka ikaika nahae kolo ma 600°C: >100 MPa

Paʻa ʻino:

- Ka maikaʻi loa intergranular corrosion kū'ē ma muli o Nb stabilization

- Ke kūpaʻa maikaʻi i ka waikawa nitric, ka waikawa acetic, nā wahi alkaline, a me ka wai kai

- Ua hoʻāʻo ʻia no ka hoʻoheheʻe ʻia o ka paʻakai hoʻoheheʻe ʻia, i hōʻoia ʻia i ka hana ma nā pahu mālama paʻakai hoʻoheheʻe CSP

- ʻOi aku ka maʻalahi o ka lua i hoʻokomo ʻia i ka chloride ma mua o 316L, hoʻemi ʻia e ka passivation a me ka mālama ʻana i ka ʻili.

4. Nā Kūlana Huahana Maʻamau

Nā ana:

- Paipu Seamless: OD 1/4”–36”, mānoanoa pā SCH10–SCH160

- Nā Paipu Pono: OD 10mm–108mm, huki anu

5. Hana Hana

1. Raw Material: Hōʻoiaʻiʻo billet kila mai ka hale a me ka honua wili

2. ʻO ka ʻōwili wela: Hoʻomoʻa ʻia nā bila i ka 1150–1200 ° C, hou ʻia a ʻōwili ʻia no nā paipu ākea nui a i ʻole nā ​​paia mānoanoa.

3. Ki'i anu: He kaha ki'i anu no ka nui pololei a me ka pau 'ana o ka ili

4. Hoʻomaʻamaʻa Wela: Hoʻopili ʻana i ka hopena ma 980–1150 ° C, hoʻopau wikiwiki i ka wai e hoʻopau i ka ua carbide

5. Welding: GTAW (TIG), PAW, a me SAW kaʻina hana, me ka hoʻohana 'ana i ka ER347 filler uea no ka stabilization; loaʻa nā koho hoʻomaʻemaʻe hope

6. Hoʻopau i ka ʻili: Pickling, passivation (HNO₃/HF), a me ka polishing mechanical (Ra ≤ 0.2µm ma ke noi)

7. Nānā: 100% RT (radiographic testing) no nā welds; kani ultrasonic, hydrostatic, PMI, intergranular corrosion ho'āʻo e like me ka makemake

6. Hōʻoia a me ka mana maikaʻi

Ua hōʻoia ʻia nā paipu kila kila ʻo Womic Steel 347H ma lalo o:

- ISO 9001:2015

- PED 2014/68/EU

- AD2000 W0

- ASME Boiler & Pressure Vessel Code

Hoʻomaʻamaʻa koʻikoʻi kēlā me kēia pūʻulu, me:

- Nā ho'āʻo mīkini (tensile, impact, flattening, flaring)

- Nā hoʻāʻo ʻino (IGC no ASTM A262)

- ʻO ka hoʻāʻo ʻole luku (UT, RT, Eddy current)

- Ka nānā ʻana a me ka traceability piha

7. Nā kahua noi

Hoʻohana nui ʻia ʻo 347H stainless steel paipu i:

- Hoʻoulu mana: Superheaters, reheaters, main pipelines in subcritical and supercritical thermal plant plants

- Solar Thermal Energy: Molten paʻakai mālama pahu pahu (450–565°C), hoʻohana ʻia i nā papahana ma Kina (Yumen, Haixi)

- Petrochemical: ʻO nā paipu umu ahi, nā mea hoʻoheheʻe hydroprocessing (kū kūʻē i nā kaiapuni H₂-H₂S-H₂O)

- Aerospace: ʻO nā ducts exhaust engine a me nā paipu ea turbine (e hana ana a hiki i 850 ° C)

- Nā mea hoʻololi wela: nā condensers wela kiʻekiʻe a me nā paipu i loko o nā refineries a me nā ʻōnaehana kai

8. Hana Ke alakai Time

- Nā Paipu Seamless (Nā Nui): 15-25 lā

- Nā ʻāpana maʻamau / ʻO nā paipu pā mānoanoa: 30-45 mau lā

- Nā Kauoha Nui: ʻO ka nui o ka 3,000 tons / mahina e hōʻoia i ka lawe wikiwiki ʻana ma lalo o nā manawa wikiwiki.

9. Packaging & Logistics

Hāʻawi ʻo Womic Steel i ka paʻa paʻa paʻa a maʻalahi:

- Nā pahu lāʻau kūpono i ke kai a i ʻole nā ​​pūʻulu kila

- Nā pāpale palaki hope, ka ʻaila anti-rust, a me ka uhi ʻana i ke kiʻiʻoniʻoni

- Hoʻopili ʻia nā pahu hoʻopuka āpau me nā kūlana ISPM-15

Loaʻa i ka Logistics:

- Nā uku hoʻokūkū CIF/CFR

- Hoʻouna wikiwiki i ka puka i ka Hikina Hema, India, ʻEulopa, a me ka Middle East

- Hoʻoikaika ʻia ka hoʻouka ʻana no ka anti-bending, anti-slippage, a me ka anti-collision i ka wā o ka lawe ʻana.

10. Nā lawelawe hana

- Piʻo (anu a wela)

- Oki pololei

- Hoʻopaʻa Threading & Hoʻopau

- Hui wiliwili (spools and elbows)

- Mīkini maʻamau no nā kiʻi

 

11. No ke aha e koho ai i ke kila Womic?

- Loko R&D & QA Lab

- ʻO ke kaulahao hoʻolako paʻa o nā mea maka e hōʻoiaʻiʻo i nā pōʻai pōkole

- He mau ʻumi makahiki o ka ʻike metallurgical, ʻoi aku hoʻi i nā alloys wela wela

- Loaʻa ka traceability a me nā palapala no ka hoʻokō pono ʻana i nā mea hana

- Mea hāʻawi hoʻonā hoʻokahi no ke kūʻai ʻana, ka hana ʻana, a me ka lawe ʻana aku i nā ʻōnaehana paipu kila kila

No nā ʻikepili ʻenehana, kumu kūʻai, a me nā ʻōlelo hoʻopiʻi papahana maʻamau, e kelepona iā Womic Steel i kēia lā. Mākaukau mākou e kākoʻo i kāu pono paipu hana kiʻekiʻe me ka pololei, ka wikiwiki, a me ka pololei.

E koho iā Womic Steel Group ma ke ʻano he hoa hilinaʻiʻO nā paipu kila kilaa me ka hāʻawi ʻole ʻana i ka hoʻokō. Welcome Inquiry!
