Hoʻopilikino ʻia ka paipu me ka helu Q345C/D/E a me ka hoʻomaʻamaʻa ʻana i ka ʻili

1. Ka wehewehe

Hoʻohana nui ʻia ka ʻāpana Hollow i ka hana kila a me ka ʻoihana mīkini, akā ʻaʻole hiki i ke ʻano maʻamau a me ka papa ke hoʻopiha i kekahi wahi kūikawā;

No ka hoʻohālikelike ʻana i nā koi kūikawā hou aʻe, hoʻomākaukau kā mākou hui e hāʻawi i kahi noi wikiwiki e like me kēia:

1) ʻano ʻano like ʻole e like me ka paipu Oval, paipu daimana, paipu berena, paipu ʻano kūikawā

2) papa hou e like me Q345B, Q345C, Q345D, Q355B, Q355C, Q355D, SS400, 304, 316, 310, 16Mo3, AL-6Xn etc.

3) ʻO ka ʻili e like me ka epoxy primer, pana pana a pēlā aku

ʻO Q345A, Q345B, Q345C, Q345D, Q345E nā ʻokoʻa o nā māka maikaʻi, e hoʻonui ana mai A a i E, ma muli o ka ʻokoʻa.

i ka wela hopena i hoʻokumu ʻia e ka ʻike o nā microelements e like me ka phosphorus a me ka sulfur, ʻo ia hoʻi ka hopena o ka wela.

ʻokoʻa A paipu kemika haku mele.

ʻAʻohe hopena ka helu Q345A; ʻo ka Q345B he haʻalulu 20 degere ma ka lumi wela; ʻo ka papa Q345C he haʻalulu 0 degere;

ʻO ka papa Q345D he haʻalulu -20 degere; ʻO ka papa Q345E he haʻalulu -40 degere. Ma nā wela haʻalulu like ʻole, ʻoi aku ka waiwai o ka haʻalulu

ʻokoʻa.

ʻAʻole emi ka ikaika o ka Q ma mua o 345Mp. Hōʻike ka papa maikaʻi i ka nui o nā mea haumia (carbon, manganese, silicon, sulfur,

phosphorus. ʻO ia ka mea haumia i loko o ke kila), a ʻo ka hele ʻana aku o A, B, C, a me D, ʻoi aku ka liʻiliʻi o ka mea haumia.

3. Waiwai Mechanical

4. Lapaʻau ʻili:

Epoxy zinc-waiwai kumu mua

Paʻa ʻana:

5. Q345 C/D/E noi:

1) Q345C seamless paipu i hoʻohana nui ʻia i loko o nā keʻena mechanical, nā mea hydraulic, hoʻohana nui ʻia i ka kemika, ka aila, ka lole,

lāʻau lapaʻau, meaʻai, mīkini a me nā ʻoihana ʻē aʻe, i hoʻohana nui ʻia i nā paipu kūpaʻa corrosion ʻoihana, nā ʻāpana a me nā ʻāpana.

2) Hoʻohana nui ʻia ʻo Q345D seamless steel pipe i nā moku, boilers, pressure vessels, oil storage tanks, bridges, power station equipment,

nā mīkini hoʻokiʻekiʻe a me ka lawe ʻana a me nā ʻāpana hana welded kiʻekiʻe.

3) Hoʻohana ʻia nā paipu cryogenic Q345E i ke kaomi kiʻekiʻe a me nā pipeline kiʻekiʻe kiʻekiʻe a me nā mea hana e like me nā mea kanu mana,

nā mea kanu mana nuklea, nā paila kiʻekiʻe, nā mea hoʻomehana wela kiʻekiʻe a me nā mea hoʻomaha. Aia ka pahu cryogenic Q345E

he ʻāpana hollow a hoʻohana nui ʻia e like me ka pipeline no ka lawe ʻana i nā wai, e like me nā pipelines no ka lawe ʻana i ka aila, ke kinoea maoli, ke kinoea, ka wai.

a me kekahi mau mea paa.

6. Nā ʻāpana hana ʻē aʻe:

5. Q345 C/D/E noi:

Q345D paipu kila maʻemaʻe, Q345D paipu kila, Q345D paipu kila, Q345E paipu kila maʻemaʻe, paipu kila maʻemaʻe no ke kiʻekiʻe

nā mea hoʻomomona kaomi, paipu kila wela haʻahaʻa no nā mea kanu mana, nā mea kanu kemika a me nā paila.
