Hōʻike paipu laina: 8-1240 × 1-200mm

maʻamau: API SPEC 5L

Hoʻohana: hoʻohana ʻia no ka lawe ʻana i ke kinoea, ka wai a me ka aila i ka ʻaila a me nā ʻoihana kinoea maoli.

API SPEC 5L-2007 (line pipe specification), i hōʻuluʻulu a hoʻopuka ʻia e ka American Petroleum Institute, hoʻohana mau ʻia ma ka honua holoʻokoʻa.Paipu laina: Lawe ʻia ka aila, ke kinoea a i ʻole ka wai i hoʻopuka ʻia mai ka lepo i ka ʻaila a me nā ʻoihana ʻenehana kūlohelohe ma o ka paipu laina.Loaʻa i nā paipu laina nā paipu ʻole a me nā paipu welded.ʻO nā wēlau paipu he mau wēlau palahalaha, nā welau wili a me nā kumu kumu;ʻO nā ʻano hoʻohui ʻana ʻo ka hoʻopau ʻana i ka welding, ka hoʻohui ʻana, ka pilina socket, etc. ʻO ka mea nui o ka paipu ʻo B, X42, X46, X56, X65, X70 a me nā mea kila ʻē aʻe..

Line pipe standard:

E hoʻohana:

ʻO ka oxygen, ka wai a me ka ʻaila lawe ʻana i nā paipu i hoʻohana ʻia i ka ʻaila a me nā ʻoihana kinoea maoli

Hana nui i nā māka paipu kila:

B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485

ʻO ka ʻae ʻana i ka nui o ka paipu laina:

1.【Ahi hoʻokaʻawale no nā paipu laina】 ʻO ka wela wela haʻahaʻa (150-250 degere)

ʻO ka hale i loaʻa ma ka haʻahaʻa wela haʻahaʻa he tempered martensite.ʻO kāna kumu e hōʻemi ai i ke koʻikoʻi o loko a me ka brittleness o ke kila kinai ʻia ma lalo o ka manaʻo o ka mālama ʻana i ka paʻakikī kiʻekiʻe a me ke kūpaʻa lole kiʻekiʻe, i mea e pale aku ai i ka haki ʻana a i ʻole ka pōʻino i ka wā e hoʻohana ai.Hoʻohana nui ʻia ia no nā mea hana ʻoki kalapona kiʻekiʻe, ana mea paahana, GB / T9711.1 pipeline steel pipes, rolling bearings a carburized parts, etc.

2.【E hoʻokaʻawale i ke ahi no nā paipu laina】Medium wela wela (250-500 degere)

ʻO ka hale i loaʻa ma ka hoʻoulu ʻana i ka mahana waena he tempered troostite.ʻO ke kumu ka loaʻa ʻana o ka ikaika kiʻekiʻe, ka palena elastic a me ka paʻakikī kiʻekiʻe.No laila, hoʻohana nui ʻia no ka mālama ʻana i nā paipu kila GB / T9711.1 pipeline a me nā ʻano hana wela, a ʻo ka paʻakikī ma hope o ka hoʻoulu ʻana ʻo ia ka HRC35-50.

3. 【Ke ahi hoʻokaʻawale no nā paipu laina】Ka wela wela (500-650 degere)

ʻO ka hale i loaʻa ma ke kiʻekiʻe wela tempering he tempered sorbite.ʻO ka mea maʻamau, ʻo ka hoʻomaʻamaʻa wela e hui pū ana i ka hoʻopau ʻana a me ka hoʻoulu ʻana i ka wela kiʻekiʻe i kapa ʻia ʻo quenching a me ka mālama ʻana, a ʻo kāna kumu e loaʻa ai nā waiwai mechanical piha me ka ikaika maikaʻi, paʻakikī, plasticity a me ka paʻakikī.No laila, hoʻohana nui ʻia ia i nā kaʻa, GB / T9711.1 pipeline steel pipes, mīkini mea hana a me nā ʻāpana koʻikoʻi ʻē aʻe, e like me ka hoʻohui ʻana i nā koʻokoʻo, nā bolts, nā gears a me nā shafts.ʻO ka paʻakikī ma hope o ka hoʻoulu ʻana he HB200-330.
