Nā mea hoʻopili paipu ASTM A234 WPB & WPC me nā kuʻekuʻe lima, tee, reducers Kiʻi i hōʻike ʻia

Wehewehe Pōkole:

Uhi kēia kikoʻī i nā mea hana kila kalapona i hana ʻia a me nā mea hana kila alloy o ke kūkulu ʻana i kahi ʻole a me ka wili ʻia. Hoʻohana ʻia kēia mau mea hana i nā paipu kaomi a me ka hana ʻana i nā ipu kaomi no ka lawelawe ʻana ma nā mahana waena a kiʻekiʻe. Pono nā mea hana no nā mea hana i ke kila i pepehi ʻia, nā mea hana, nā kaola, nā papa, nā huahana tubular i wili ʻia a i ʻole nā mea hana fusion me ka metala hoʻopihapiha i hoʻohui ʻia. Hiki ke hana ʻia nā hana hana a i ʻole ke ʻano ma ke kuʻi ʻana, ke kaomi ʻana, ka ʻoki ʻana, ka hoʻopuka ʻana, ka hoʻohaʻahaʻa ʻana, ka ʻōwili ʻana, ke kūlou ʻana, ka wili ʻana i ka fusion, ka mīkini ʻana, a i ʻole ma ka hui pū ʻana o ʻelua a ʻoi aku paha o kēia mau hana. Pono e hoʻopili ʻia ke kaʻina hana hana i ʻole e hana i nā hemahema ʻino i nā mea hana. ʻO nā mea hana, ma hope o ke kūkulu ʻana i kahi mahana kiʻekiʻe, e hoʻomaʻalili ʻia i kahi mahana ma lalo o ka pae koʻikoʻi ma lalo o nā kūlana kūpono e pale aku i nā hemahema ʻino i hoʻokumu ʻia e ka hoʻomaʻalili wikiwiki loa, akā ʻaʻole i ʻoi aku ka wikiwiki ma mua o ka helu hoʻomaʻalili i ka ea mālie. Pono e hoʻokō ʻia nā mea hana i ka hoʻāʻo tension, ka hoʻāʻo paʻakikī, a me ka hoʻāʻo hydrostatic.

Hana ʻana

Hiki ke hana ʻia nā mea hoʻopili paipu kila kalapona ASTM A234 mai nā paipu humuhumu ʻole, nā paipu i hoʻopaʻa ʻia a i ʻole nā papa ma ke ʻano o ke kaomi ʻana, ka ʻoki ʻana, ka extruding, ke kulou ʻana, ka hoʻopili ʻana i ka fusion, ka mīkini, a i ʻole ma ka hui pū ʻana o ʻelua a ʻoi aku paha o kēia mau hana. ʻO nā mea hoʻopili āpau e komo pū ana me nā mea hoʻopili i nā huahana tubular mai kahi i hana ʻia ai nā mea hoʻopili e hana ʻia e like me ka ASME Section IX. ʻO ka mālama wela ma hope o ka hoʻopili ʻana ma 1100 a 1250°F [595 a 675°C] a me ka nānā ʻana i ka radiographic e hana ʻia ma hope o ke kaʻina hana hoʻopili.
