Huahana Huahana

He aha ka STPG 370 Pipe Material?

ʻO STPG 370 kahi pae paipu kila haʻahaʻa haʻahaʻa i hōʻike ʻia ma ke kūlana Iapana JIS G 3454.

Loaʻa iā STPG 370 ka ikaika tensile haʻahaʻa o 370 MPa a me ka ikaika haʻahaʻa haʻahaʻa o 215 MPa.

Hiki ke hana ʻia ʻo STPG 370 ma ke ʻano he paipu kila ʻole a i ʻole nā paipu kila welded me ka hoʻohana ʻana i ke kaʻina hana hoʻoheheʻe uila (ERW).He kūpono ia no ka hoʻohana ʻana i nā ʻōnaehana paipu kaomi me nā mahana hana a hiki i 350 ° C.

A laila, e nānā mākou i ka STPG 370 mai nā kaʻina hana, ka haku mele, nā waiwai mechanical, nā hoʻokolohua hydrostatic pressure, ka hoʻāʻo ʻole luku, a me ka uhi galvanized.

Kaʻina Hana Hana

Hiki ke hana ʻia ʻo JIS G 3454 STPG 370 me ka hoʻohana ʻana i kamaʻemaʻe or ERWkaʻina hana, hui pū me nā ʻano hoʻopau kūpono.

Ma waho aʻe o ka ikaika tensile, ka ikaika tensile, a me ka elongation i ʻōlelo ʻia ma luna nei, aia kekahi hoʻāʻo palahalaha a me ka hiki.

Ho'āʻo palahalaha: Ke hiki ka mamao ma waena o nā papa ʻelua i ka mamao H i ʻōlelo ʻia, ʻaʻohe hemahema a māwae paha ma ka ʻili o ka paipu kila.

ʻO ke kūpale ʻana: Pono e hoʻopio ʻia ka paipu 90° ma ka radius o 6 manawa o kona anawaena o waho.Pono ʻole ka paia o ka paipu i nā hemahema a i ʻole nā māwae.

ʻO ka hoʻāʻo Hydrostatic a i ʻole ka hoʻāʻo ʻole luku

Hāʻawi ʻia kēlā me kēia paipu kila i kahi hoʻāʻo hydrostatic a i ʻole ka hoʻāʻo ʻole luku e nānā i nā hemahema i ʻike ʻole ʻia e ka maka.

Hoʻāʻo Hydrostatic

E like me ka papa kuhikuhi o ka mānoanoa o ka pā o ka paipu kila, koho i ka waiwai kaomi wai kūpono, mālama ia no ka liʻiliʻi loa 5 kekona, a e nānā inā e kahe ana ka paipu kila.

Ho'āʻo hoʻopōʻino ʻole

Inā hoʻohana ʻia ka nānā ʻana ultrasonic, pono e hoʻokumu ʻia ma kahi kūlana koʻikoʻi ma mua o ka hōʻailona papa UD ma JIS G 0582.

Inā hoʻohana ʻia ka hoʻāʻo eddy o kēia manawa, pono e hoʻokumu ʻia ma kahi maʻamau i ʻoi aku ke koʻikoʻi ma mua o ka hōʻailona papa EY ma JIS G 0583.

Galvanized

I JIS G 3454, kapa ʻia nā paipu kila ʻolepaipu eleelea ua kapaia na paipu kila galvanizedpaipu keokeo.

Paipu keʻokeʻo: paipu kila galvanized

Paipu ʻeleʻele: paipu kila non-galvanized

ʻO ke kaʻina hana no nā paipu keʻokeʻo, ʻo nā paipu ʻeleʻele kūpono i pana ʻia a ʻoki ʻia paha e wehe i nā mea haumia mai ka ʻili o ka paipu kila a laila galvanized me ka zinc e kū ana i ke kūlana JIS H 2107 o ka liʻiliʻi loa o ka papa 1. Hoʻokō ʻia nā mea ʻē aʻe. e like me ka JIS H 8641 maʻamau.

Nānā ʻia nā hiʻohiʻona o ka uhi zinc e like me nā koi o JIS H 0401, Paukū 6.

E pili ana iā mākou

Mai kona hoʻokumu ʻana i ka makahiki 2014,Ke kila Botopua lilo i mea hoʻolako alakaʻi o ka paipu kila kalapona ma Northern China, i ʻike ʻia no ka lawelawe maikaʻi loa, nā huahana kiʻekiʻe, a me nā hāʻina piha.

Hāʻawi ka hui i nā ʻano paipu kila kalapona a me nā huahana pili, me ka seamless, ERW, LSAW, a me ka paipu kila SSAW, a me ka laina piha o nā paipu paipu a me nā flanges.ʻO kāna mau huahana kūikawā pū kekahi me nā mea kila kiʻekiʻe a me nā austenitic stainless steel, i hana ʻia e hoʻokō i nā koi o nā papahana pipeline like ʻole.
