ʻO ASTM A694 kahi papa kila ʻAmelika
ASTM A694 Forgings for Carbon and Alloy Steel Pipe Flanges, Fittings, Valves and Parts for High Pressure Transmission Equipment
Loaʻa iā A694 ka huina o F42 F46 F48 F50 F52 F56 F60 F65F70
ʻO A694 kahi papa kila ma ʻAmelika Hui Pū ʻIa, a ua kokoke kona haku mele i ka Q345D ma Kina. Pono ʻo Q345D e hana i nā kaʻina hana mālama wela ma mua o ka hiki ʻana i nā waiwai mechanical o A694 F60.

Eia kekahi,ʻo ASTM A694 Gr.F60 kekahi mea hao hao haʻahaʻa i hoʻohanaʻia no nā paipu paipu ma lalo o ke kiʻekiʻe kiʻekiʻe a me ka mahana wela, no laila ua kapaʻiaʻo A694 F60 kiʻekiʻe kiʻekiʻe.
Hoʻohana pinepine ʻia kēia mea no nā pilina pipeline kiʻekiʻe i ka ʻaila, ke kinoea maoli a me nā ʻoihana kemika, a loaʻa iā ia ka ikaika tensile kiʻekiʻe a me ka pale ʻana i ka corrosion.

No ka laula paakiki oASTM A694 Gr.F60,ʻaʻohe koi paʻakikī kikoʻī. ʻO ka paʻakikī e pili ana i nā kūlana mālama wela kūikawā a me ke kūlana waiwai. ʻO ka maʻamau, hoʻāʻo ʻia ka pae paʻakikī o ka mea A694 F60 ma lalo o ka paʻakikī Brinell (HB) a i ʻole ka paʻakikī ʻo Rockwell (HRC). E ʻokoʻa ka waiwai paʻakikī e like me ke ʻano kemika, nā kūlana mālama wela a me ke kaʻina hana o ka mea.

E lawe i ka flange weld butt o A694 F60 i laʻana e wehewehe ai:

A694 F60puʻu welding flangeʻAʻole maʻalahi ka deform, he sila maikaʻi a hoʻohana nui ʻia. Hoʻopili ia i nā pipeline me ka nui o ke kaomi a i ʻole ka fluctuations wela a i ʻole ka wela kiʻekiʻe, ke kiʻekiʻe kiʻekiʻe a me nā pipeline haʻahaʻa haʻahaʻa. Hoʻohana maʻamau ia no ka hoʻopili ʻana i nā pipelines a me nā valve me PN ʻoi aku ka nui ma mua o 2.5MPa; Hoʻohana ʻia ia i nā pipeline e lawe ana i ka media pipiʻi, flammable a pahū. He lōʻihi kona ola lawelawe. Wahi a ka ʻikepili hoʻāʻo corrosion, hiki i kona ola lawelawe ke hiki i 100 mau makahiki a ʻaʻole pono e mālama. No laila, ʻoi aku ka maikaʻi o kāna lākiō hana-kūʻai, haʻahaʻa ke kumu kūʻai o ke ola hana, a he mea nui kāna mau waiwai waiwai.

Hōʻike ʻia ʻo A694 F60 butt welding flange e ka pilina hilinaʻi a palekana, hana maʻalahi a wikiwiki hoʻi, ka hoʻomaʻemaʻe maikaʻi a me ka hoʻomalu ʻana i ke kaiapuni, ka liʻiliʻi o ke kahe kahe ʻana, ka paʻa ʻana o ka ʻōnaehana, ka wehe ʻana a me ka hoʻonohonoho huna ʻana, ʻaʻohe hana hou a mālama, ʻoi aku ka maikaʻi o ka hoʻokele waiwai, a laula noi ākea. He mea pili ia i ka hoʻoili kīwila haʻahaʻa haʻahaʻa e like me ke anuanu a me ka wai wela, ka wai inu pololei, ka hoʻomehana, ka ea ea, ka pale ahi, ke kinoea, a me nā mea ʻē aʻe, a me ka lāʻau lapaʻau, ka mea inu, ka meaʻai. nā ʻoihana ʻē aʻe.
