He Introduction to Concentric Reducer

Ua kapa ʻia ka mea hoʻemi i waena o ka laina pololeimea hoemi concentric.ʻO ke kaʻina hana maʻamau e hoʻemi, hoʻonui a hōʻemi paha me ka hoʻonui ʻana, a hiki ke hoʻohana ʻia ke stamping no ka hōʻemi ʻana i nā paipu o kekahi mau kikoʻī.

Hōʻike huahana:

3/4 “X1/2″ — 48 “X 40″ [DN 20 X 15 --- 1200 X 1000]

Ana mānoanoa o ka pā:

Sch 5s –160

Nā kūlana hoʻokō:

GB/T12459-2005, ANSI, JIS, BS, DIN, UNI, etc.

Mea huahana:

Ke kila kalapona, Ke kila kila

Keʻano hoʻopili:

Hiki ke hoʻopili kūikawā ʻia nā hihia lāʻau fumigation free a me nā pallets e like me nā koi o ka mea kūʻai aku.

noi huahana:

ʻO ka ʻenekinia paipu ʻaila ʻaila, ʻenekinia pipeline kūlohelohe, mea kanu kemika, mea kanu mana, hale moku, lāʻau lapaʻau, waiu, pia, inu, mālama wai, etc.

Nānā:

Ke kila kalapona: 10 #, 20 #, A3, Q235A, 20G, 16Mn, ASTM A234, ASTM A105, etc.
Ke kila kila: ASTMA403, 1Cr18Ni9Ti, 0Cr18Ni9, 00Cr19Ni10, 00Cr17Ni14Mo2, 304, 304L, 316, 316L, etc.

Pūnaehana maʻamau:

ʻElua mau ʻōnaehana o ka paipu flange ma ka honua, ʻo ia ka ʻōnaehana pipe flange ʻEulopa i hōʻike ʻia e ka German DIN (me ka Soviet Union mua) a me ka ʻōnaehana pipe flange ʻAmelika i hōʻike ʻia e ka flange paipu ʻAmelika ANSI.Eia kekahi, aia nā flanges paipu JIS ma Iapana, akā hoʻohana wale ʻia lākou no nā mea pono i nā mea kanu petrochemical, a he liʻiliʻi ka hopena honua.ʻO kēia ka hoʻolauna pōkole o nā flanges paipu ma nā ʻāina like ʻole:
1. ʻO nā flanges paipu ʻEulopa i hōʻike ʻia e Kelemania a me ka Soviet Union mua
2. ʻO ka maʻamau flange paipu ʻAmelika, hōʻike ʻia e ANSI B16.5 a me ANSI B 16.47
3. Nā kūlana flange paipu Pelekāne a me Palani, ʻelua kūlana flange casing no kēlā me kēia ʻāina.
ʻO ka hōʻuluʻulu ʻana, hiki ke hōʻuluʻulu ʻia nā kūlana flange paipu honua ma ke ʻano he ʻelua ʻōnaehana flange paipu like ʻole a hoʻololi ʻole ʻia: kahi ʻōnaehana pipe flange ʻEulopa i hōʻike ʻia e Kelemania;ʻO ka mea ʻē aʻe ka ʻōnaehana flange paipu ʻAmelika i hōʻike ʻia e ʻAmelika Hui Pū ʻIa.

Hoʻokaʻawale

1. Hoʻokaʻawale ʻia e ka mea:
Ke kila kalapona: ASTM/ASME A234 WPB, WPC
Ke kila kila: ASTM/ASME A403 WP 304-304L-304H-304LN-304N
ASTM/ASME A403 WP 316-316L-316H-316LN-316N-316Ti
ASTM/ASME A403 WP 321-321H ASTM/ASME A403 WP 347-347H
2. E like me ke ʻano hana, hiki ke hoʻokaʻawale ʻia i ka paʻi ʻana, kaomi, forging, hoʻolei, etc.
3. Hiki ke hoʻokaʻawaleʻia nā kūlana hana i nā kūlana aupuni, nā uila uila, nā moku moku, nā mea kemika, nā wai wai, nā kūlanaʻAmelika, nā kūlana German, nā kūlana Iapana, nā kūlana Lūkini, a me nā mea'ē aʻe.

Nā hiʻohiʻona māhele

(1) ʻO ka manawa kūlou i hoʻokumu ʻia e ka ʻokoʻa o ke kaomi wahi ma waena o nā wēlau nui a liʻiliʻi o ka concentricmea hoemima lalo o ka hana a ka puʻe o loko e hoʻomaka ai ke ʻano o ka wehe ʻana o ka hope nui a emi iki ka hope liʻiliʻi;

(2) Ma lalo o ka hana o ka puʻe kūloko, ke koʻikoʻi pōʻaiapuni ma ka ʻili o loko o ka hopena nui o ka ʻaoʻao eccentric a me ka ʻili o waho o ka waena o ka ʻaoʻao eccentric o kamea hoemi eccentricʻo ka nui loa.
