Seamless mpweya zitsulo chitoliro ndi mtundu wa chitoliro chimagwiritsidwa ntchito m'munda mafakitale. Kupanga kwake sikuphatikiza kuwotcherera kulikonse, chifukwa chake amatchedwa "seamless". Chitoliro chamtunduwu nthawi zambiri chimapangidwa ndi chitsulo chapamwamba kwambiri cha carbon structural steel kapena alloy steel ndi kutentha kapena kuzizira. Seamless carbon steel pipe imagwiritsidwa ntchito kwambiri m'magawo ambiri monga mafuta, gasi, makampani opanga mankhwala, boilers, kufufuza kwa geological ndi kupanga makina chifukwa cha mawonekedwe ake a yunifolomu ndi mphamvu zake, komanso kukana kwabwino ndi kukana kutentha. Mwachitsanzo, mapaipi achitsulo osasunthika a ma boiler otsika komanso apakatikati amagwiritsidwa ntchito makamaka popanga mapaipi otentha kwambiri, mapaipi amadzi otentha ndi mapaipi otenthetsera kwambiri opangira ma boilers osiyanasiyana otsika komanso apakatikati. Ndipo mapaipi achitsulo osasunthika a ma boilers othamanga kwambiri amagwiritsidwa ntchito kupanga mapaipi otenthetsera pamwamba pa ma boiler amadzi okhala ndi kuthamanga kwambiri komanso pamwamba. Kuphatikiza apo, mapaipi achitsulo osasunthika atha kugwiritsidwanso ntchito popanga zida zamakina ndi zida zamakina, monga ma shaft amagalimoto, mafelemu anjinga, ndi zitsulo zomanga. Chifukwa chazomwe zimapangidwira, mapaipi achitsulo osasunthika amatha kupirira kupsinjika kwakukulu pakagwiritsidwa ntchito ndipo samakonda kutayikira, motero ndikofunikira kwambiri potumiza madzi.
Gulu la mapaipi opanda zitsulo za carbon zitsulo makamaka zimachokera ku zipangizo zopangira ndi ntchito. Malingana ndi njira yopangira, mapaipi achitsulo opanda mpweya amatha kugawidwa m'magulu awiri: otentha-wotentha ndi ozizira (wokoka). Mapaipi achitsulo osasunthika otentha amaphatikiza mapaipi achitsulo, mapaipi achitsulo otsika komanso apakatikati, mapaipi achitsulo opopera kwambiri, mapaipi azitsulo zazitsulo, mapaipi achitsulo chosapanga dzimbiri, mapaipi ong'ambika amafuta ndi mitundu ina, pomwe oziziritsa (wokoka) mapaipi achitsulo opanda msoko amaphatikizapo mapaipi azitsulo a carbon woonda-mipanda, mapaipi achitsulo opangidwa ndi mipanda yopyapyala, mapaipi achitsulo osapanga dzimbiri opyapyala komanso mipope yachitsulo yooneka ngati yapadera. The specifications of seamless zitsulo mapaipi zambiri anasonyeza millimeters akunja awiri ndi khoma makulidwe. Zidazi zikuphatikiza zitsulo wamba komanso zapamwamba za carbon structural steel (monga Q215-A mpaka Q275-A ndi 10 mpaka 50 zitsulo), chitsulo chochepa cha alloy (monga 09MnV, 16Mn, etc.), chitsulo cha alloy ndi chitsulo chosapanga dzimbiri acid. . Kusankhidwa kwa zinthuzi kumagwirizana ndi mphamvu, kukana kupanikizika ndi kukana kwa dzimbiri kwa payipi, kotero padzakhala zofunikira zosiyana zakuthupi m'mafakitale osiyanasiyana. Mwachitsanzo, zitsulo zotsika za carbon monga No. 10 ndi No. . Kuphatikiza apo, mapaipi achitsulo osasunthika amayenera kuyang'aniridwa bwino kwambiri panthawi yopanga, kuphatikiza kuyang'anira kapangidwe ka mankhwala, kuyezetsa katundu wamakina, kuyezetsa kuthamanga kwa madzi, ndi zina zotere, kuti zitsimikizire kudalirika kwawo komanso chitetezo m'malo osiyanasiyana ogwira ntchito. Njira yopangira mapaipi opanda mpweya wachitsulo ndizovuta kwambiri. Zimaphatikizapo masitepe angapo monga perforation, kugudubuza kotentha, kuzizira kozizira kapena kujambula kozizira kwa ingots kapena machubu olimba, ndipo sitepe iliyonse imafuna kuwongolera bwino kuti zitsimikizire mtundu wa mankhwala omaliza. Mwachitsanzo, kupanga otentha adagulung'undisa mipope zitsulo kumafuna kutentha chubu billet pafupifupi 1200 digiri Celsius, ndiye kuboola izo kupyolera perforator, ndiyeno kupanga zitsulo chitoliro mwa atatu wodzigudubuza oblique anagubuduza, mosalekeza Kugubuduza kapena extrusion. Mapaipi achitsulo osasunthika oziziritsidwa amafunikira chubu billet kuti azifutsa ndi kuthiridwa mafuta asanakunkhunizeni ozizira (kukokedwa) kuti akwaniritse kukula ndi mawonekedwe omwe mukufuna. Njira zopangira zovutazi sizimangotsimikizira kuti mkati mwa chitoliro chopanda chitsulo chosasunthika, komanso zimapatsa kulondola kwapamwamba komanso kutha kwapamwamba. Muzochita zothandiza, mapaipi achitsulo osasunthika a carbon steel amagwiritsidwa ntchito kwambiri m'mafakitale ambiri monga mafuta, gasi, makampani opanga mankhwala, magetsi, kutentha, kusunga madzi, kumanga zombo, ndi zina zotero chifukwa cha ntchito yawo yabwino komanso yodalirika. Iwo ndi gawo lofunika kwambiri pamakampani amakono. Kaya m'malo otentha komanso othamanga kwambiri kapena muzofalitsa zowononga, mapaipi achitsulo osasunthika amatha kuwonetsa magwiridwe antchito awo abwino kwambiri ndikupereka zitsimikizo zolimba zogwirira ntchito motetezeka m'mafakitale osiyanasiyana.
The awiri a seamless carbon zitsulo mapaipi akhoza osiyanasiyana DN15 kuti DN2000mm, khoma makulidwe zimasiyanasiyana 2.5mm kuti 30mm, ndi kutalika nthawi zambiri pakati 3 ndi 12m. Magawo ang'onoang'onowa amalola mapaipi achitsulo osasunthika kuti azigwira ntchito mokhazikika pansi pazovuta komanso kutentha kwambiri, ndikuwonetsetsa kudalirika kwawo panthawi yoyendetsa ndi kukhazikitsa. Malinga ndi muyezo wa GB/T 17395-2008, kukula, mawonekedwe, kulemera ndi kupatuka kovomerezeka kwa mapaipi achitsulo osasunthika kumayendetsedwa mosamalitsa kuonetsetsa kuti zinthu zili bwino komanso chitetezo. Posankha mipope yachitsulo ya carbon zitsulo, ndikofunika kuganizira zamkati mwake, m'mimba mwake, makulidwe ndi kutalika kwake, zomwe ndizofunikira kwambiri pozindikira momwe payipi ikuyendera. Mwachitsanzo, m’mimba mwake m’kati mwake umatsimikizira kukula kwa danga loti madziwo adutse, pamene m’mimba mwake ndi makulidwe akunja amagwirizana kwambiri ndi mphamvu ya chitoliro chonyamula chitoliro. Kutalika kumakhudza njira yolumikizira chitoliro ndi zovuta za kukhazikitsa.
