E pili ana i nā Aluminum Flanges

Flangehe mea hookui poepoe a huinaha paha me na puka ma kona mau kihi no ka hookui ana i na lehelehe ma o na wili a i ole nati. Hana ʻia nā flanges alumini me ka alumini alumini a hoʻohana nui ʻia i nā ʻōnaehana pipeline e hāʻawi i nā wahi pili ma waena o nā ʻāpana like ʻole, a laila kūkulu ʻia nā ʻoihana pipeline nui aʻe.

ʻAno:

1. Flange palahalaha: ʻO ia ke ʻano maʻalahi a maʻamau o ka flange alumini, hoʻohana mau ʻia e hoʻopili i nā paipu pololei a i ʻole nā ​​​​mea hana.
2. Slip On flange: Ke hoʻohālikelike ʻia me nā flanges pā, he ʻāʻī hou aʻe a hiki ke paheʻe i loko o ka pipeline. Hoʻopaʻa ʻia ia e ka welding a kūpono i nā noi haʻahaʻa haʻahaʻa a me nā haʻahaʻa haʻahaʻa haʻahaʻa.
3. Weld Neck flange: Me ka ʻāʻī lōʻihi, kūpono no nā noi kiʻekiʻe-mehana a me ke kaomi kiʻekiʻe, welded i nā pipeline. He liʻiliʻi ka laulā o ka hoʻohana.

Kūlana:

ʻO nā kūlana flange alumini maʻamau ka:
1.ANSI maʻamau: He kūlana i kūkuluʻia e ka American National Standards Institute, e like me ANSI B16.5.
2.ASME maʻamau: He kūlana i kūkuluʻia e ka American Society of Mechanical Engineers, e like me ASME B16.5.
3.DIN maʻamau: Kelemāniaʻoihanaʻoihana, e like me DIN 2576.
4.JIS maʻamau: ʻO ke kūlana ʻoihana Iapana, e like me JIS B2220.

Nā pono a me nā pōʻino:

Pono:

1. Māmā a me ka ikaika kiʻekiʻe: Loaʻa i ka alumini alumini nā hiʻohiʻona o ka māmā a me ka ikaika kiʻekiʻe, e kōkua ana e hoʻemi i ke kaumaha o nā pūnaewele pipeline.
2. Ke kū'ēʻana i ka pōʻino: Loaʻa i nā alumini alumini ke kūpaʻa maikaʻi a kūpono i nā noiʻaʻole i koi aku i ke kūpaʻa kiʻekiʻe.
3. Conductivity: ʻO ka alumini kahi mea hoʻokele maikaʻi loa, kūpono i nā kūlana e pono ai ka conductivity.
4. He mea maʻalahi ka hanaʻana: He mea maʻalahi ka alumini alumini a maʻalahi ka hana hana.

Nā hemahema:

1. ʻAʻole kūpono i nā noi kiʻekiʻe a me ke kaomi kiʻekiʻe: ʻO nā flanges alumini he haʻahaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa paʻa, ʻaʻole kūpono ia no nā noi kiʻekiʻe a me ke kiʻekiʻe.
2. Maʻalahi ke komo: Ke hoʻohālikelike ʻia me kekahi mau metala paʻakikī, ʻoi aku ka maʻalahi o nā alumini alumini i ka friction a me ka ʻaʻahu.
3. Nā koi ʻenehana hoʻoheheʻe kiʻekiʻe: Ma kekahi mau noi e koi ana i ka wili, ʻoi aku ka kiʻekiʻe o nā koi ʻenehana alumini.
