Yakaderera uye yepakati pressure boiler machubhu anogadzirwa neingots kana akasimba mabhidhiyo anonamirwa kuita burr chubhu, uye ipapo inopisa yakakungurutswa, inotonhora inokungurutswa kana kutonhora kufona.Seamless simbi pombi ine nzvimbo inokosha muChina simbi pombi indasitiri.Maererano nenhamba dzisina kukwana, China iripo isina musono pombi kugadzirwa makambani anenge 240 kupfuura, musono simbi pombi chikwata anenge 250 seti, gore negore kugadzirwa kukwanisa anenge mamiriyoni 4,5 matani.Kubva pane caliber point of view, <φ76, accounting for 35%, <φ159-650, accounting for 25%.Panyaya yemhando, 1.9 miriyoni matani emachubhu-chinangwa, achiverengera 54%;760,000 matani epetroleum tubes, anoverengera 5.7%;150,000 matani e hydraulic pillars, precision tubes, inoverengera 4.3%;machubhu asina tsvina, machubhu anotakura, machubhu emotokari anokwana matani 50,000, achiverengera 1.4%.

Yakaderera uye yepakati kudzvanywa boiler chubhu michini zvivakwa: tensile simba σb (MPa): ≥ 410 (42) goho simba σs (MPa): ≥ 245 (25) elongation δ5 (%): ≥ 25 chikamu shrinkage ψ (%): ≥ 5 , kuoma: kwete kupisa kwekupisa, ≤ 156HB, saizi yemuenzaniso: saizi yemuenzaniso 25mm kupisa kwekupisa kutsanangurwa uye sangano remetallographic: kutsanangurwa kwekupisa kwekupisa: kwakajairwa, 910 ℃, Kutonhora kwemhepo.Metallographic sangano: ferrite + pearlite.

Yepakati uye yakaderera kumanikidza boiler chubhu kuuraya chiyero: GB3087-1999 isina musono simbi chubhu kune yakaderera uye yepakati pressure boiler.

Machubhu epakati nepakati uye akadzika anopisa akakungurutswa uye anotonhora akadhonzwa (akakungurutswa) asina musono machubhu emhando yepamusoro kabhoni yesimbi yesimbi inoshandiswa kugadzira machubhu anopisa zvakanyanya, machubhu emvura akakungurutswa uye machubhu anopisa anopisa emagetsi emagetsi, machubhu mahombe ehutsi, machubhu madiki eutsi uye arch. zvidhinha machubhu ezvimiro zvakasiyana zvepasi uye zvepakati pressure boilers.Inonyanya kushandiswa kumaindasitiri boilers uye anorarama boilers kutakura yakaderera uye yepakati pressure fluid pombi.Iyo inomiririra zvinhu ndeye 10 uye 20 gauge simbi.
