PSL1 Steel Pipe: Nā kūlana, nā noi a me nā mea'ē aʻe

PSL1he pae kikoʻī huahana ma ka API 5L maʻamau a hoʻohana nui ʻia no nā paipu kila pipeline i ka ʻoihana aila a me ke kinoea.

PSL1 Paipu kila

Hoʻokaʻawale

E like me ke ʻano opaipu kila: paipu kila maʻemaʻe a me ka paipu kila welded.

E like me ke ʻano opaipu hope: welau palahalaha, welau wili, welau kumu, a me ka welau paipu no na pipili kūikawā.

Wahi akila kila:

L-series (L + liʻiliʻi liʻiliʻi e hāʻawi i ka ikaika ma MPa)

L175 a me L175P,L210,L245,L290,L320,L360,L390,L415,L450,L485

X-series (X + liʻiliʻi liʻiliʻi huahua ikaika ma 1000 psi)

A25 a me A25P,X42,X46,X52,X56,X60,X65,X70

Nā Papa kila maʻamau

ʻO ka Papa A a me ka Papa B he mau māka kila maʻamau ʻaʻole i wehewehe ʻia e nā kūlana ikaika hoʻohua, me ka Papa A e pili ana i ka L210 a me ka Papa B e pili ana i ka L245.

Ka Hana Hana o PSL1 Steel Pipe

Ka Hana Hana o PSL1 Steel Pipe

Mea Maka

Ingot, billet, billet, strip (coil) or plate

Hana ʻia e nā kaʻina hana:
a) ke kaʻina hana hoʻololi alkaline e puhi ana i ka oxygen.
b) ke kaʻina hoʻoheheʻe ʻana i ka umu uila.
c) ka umu ahi palahalaha i huiia me ka ladle ho'oma'ema'e.

Nā Kūlana Hoʻouna no PSL1

ʻO nā hoʻomaʻamaʻa wela no ka paipu kila PSL1, ʻo ia ka ʻōwili, ka ʻōwili maʻamau, ka ʻōwili thermo-mechanical, thermo-mechanical forming, normalizing forming, normalizing, a me ka hoʻomaʻamaʻa ʻana a me ka hoʻomaʻamaʻa ʻana, e hoʻomaikaʻi ai i nā waiwai mechanical a me ka hoʻonohonoho pono o ka paipu.

ʻO ka leka P ma L175P e hōʻike ana i ke kila he nui o ka phosphorus.

Hoʻohui Kimia o PSL1 Pipe kila

ʻO ka hui kemika o ka paipu kila PSL1 ua wehewehe paʻa ʻia i ka maʻamau API 5L e hōʻoia i ka maikaʻi o ka paipu i nā waiwai mechanical a me ka pale ʻana i ka corrosion e hoʻololi i nā ʻano o ka lawe ʻana i nā kaiapuni.

E hoʻoholo ʻia ka hui kemika o ka paipu kila PSL1 no t > 25.0 mm e ka ʻaelike.
