1. Paipu kila mānoanoaʻoki: E like me ka lōʻihi o ka pipeline i koi ʻia, pono e ʻoki ʻia ka paipu me ka ʻike metala a i ʻole ka ʻike niho ʻole. Ke hoʻohana ʻia ka wili wai i ka ʻoki ʻana, pono e pale ʻia nā mea maka. I ka wā e ʻoki ai, pono e hoʻohana ʻia nā mea pale ahi a me nā mea wela e like me nā baffles ma nā ʻaoʻao ʻelua o ka haʻi e hopu ai i nā hunaahi a me ka hao hoʻoheheʻe wela e hāʻule i ka wā e ʻoki ai e pale i nā mea maka. ʻO ka ʻili iʻa mua.

2. Pili paipu kila mānoanoa: Ma hope o ka pau ʻana o ka hoʻoponopono ʻana i ka plastik, e hoʻopili i ka paipu a me nā paipu paipu a hoʻokomo i nā pad rubber ma waena o nā flanges i ka wā o ka hoʻopili ʻana, a hoʻopaʻa i nā bolts i ka moku i hoʻopaʻa ʻia.

3. ʻO ka hoʻomaʻamaʻa ʻia ʻana o ka paipu kila mānoanoa: Ma hope o ka poli ʻana, e hoʻohana i ka oxygen a me C2H2 e wela ai ka waha o ka paipu ma waho o ka paipu a hiki i ka hoʻoheheʻe ʻia ʻana o ka ʻili o loko, a laila e hoʻopili pono ka mea hana akamai i ka pauka i hoʻomākaukau ʻia i ka waha paipu. , Pono e hoʻolohe pono i ka hoʻopili ʻia ʻana ma kahi, a ʻo ka pā flange e hamo ʻia ma luna o ka laina kū wai. Ma kēia kaʻina hana, pono e mālama ponoʻia ka mahana wela. Inā kiʻekiʻe loa ka mahana, e hana ʻia nā ʻōhū i ka wā o ke kaʻina hana i uhi ʻia. Inā haʻahaʻa loa ka mahana, ʻaʻole e heheʻe ka pauka plastic i ka wā o ke kaʻina hana uhi. ʻO nā kūlana i luna e hana i ka plastic ma hope o ka hoʻohana ʻana i ka pipeline. Me ke ʻano o ka hoʻoheheʻe ʻia ʻana o ka papa, ua ʻino ʻia ka ʻāpana paipu kila mānoanoa o ka pipeline i ka wā hope.

4. ʻO ka waha paipu kila mānoanoa e wili ai: Ma hope o ka ʻoki ʻana, pono e hoʻohana ʻia kahi wili kihi e wili ai i ka papa plastik o ka waha paipu. ʻO ke kumu o ka pale ʻana i ka hoʻoheheʻe ʻana a i ʻole ke puhi ʻana i ka papa plastik i ka wā o ka wili flange a me ka luku ʻana i ka paipu. E ho ohana i ka wili kihi e poni ai i ka papa plastik o ka nozzle.

passivity e hana i kahi kiʻiʻoniʻoni pale ma ka ʻili. ʻO nā paipu kila mānoanoa i loaʻa i ka hardenability kiʻekiʻe, ka machinability maikaʻi, ka plasticity deformation anuanu, a me ka weldability; ʻAʻole hoʻi i emi nui ka paʻakikī o ke kila i ka wā o ka mālama ʻana i ka wela, akā he ikaika kiʻekiʻe kona a paʻa i ke kūpaʻa, ʻoi aku ka nui o ka wai. He kiʻekiʻe koʻikoʻi; akā, ʻo kēia kila he mea maʻalahi loa ia i nā kiko keʻokeʻo, he ʻano e huhū brittleness a me ka overheating sensitivity i ka wā e mālama ai i ka wela, he ikaika kiʻekiʻe a paʻakikī, paʻakikī maikaʻi, liʻiliʻi liʻiliʻi i ka wā e kinai ana, a me ka ikaika kolo kiʻekiʻe i nā wela kiʻekiʻe A me ka ikaika lōʻihi. Hoʻohana ʻia ia e hana i nā forgings e koi ana i ka ikaika kiʻekiʻe ma mua o ke kila 35CrMo a ʻoi aku ka nui o ka pauku kinai ʻia a me ka huhū, e like me nā mīkini nui no ka locomotive traction, supercharger transmission gears, hope axles, connecting rods a me nā mea hoʻopili puna i hoʻouka nui ʻia. Hiki ke hoʻohana ʻia i nā hui paipu drill a me nā mea lawaiʻa no nā pūnāwai hohonu ʻaila ma lalo o 2000m a hiki ke hoʻohana ʻia ma ke ʻano he poni no nā mīkini kuʻi.
