1. Kupanga ndi kupanga njira zopangira zitsulo zopanda zitsulo zingathe kugawidwa m'mapaipi otentha otentha, mapaipi ozizira ozizira, mapaipi ozizira, otuluka kunja, ndi zina zotero malinga ndi njira zosiyanasiyana zopangira.

1.1. Mapaipi opanda msoko otenthedwa ndi otentha nthawi zambiri amapangidwa pamagetsi odzigudubuza okha. Chubu cholimba chopanda kanthu chimawunikiridwa ndipo zolakwika zapamtunda zimachotsedwa, zimadulidwa mu utali wofunikira, zokhazikika kumapeto kwa chubu chopanda kanthu, ndiyeno zimatumizidwa ku ng'anjo yowotchera kuti itenthetse ndi kuboola pamakina okhomerera. Imapitirizabe kuzungulira ndi kupita patsogolo panthawi yoboola mabowo. Mothandizidwa ndi odzigudubuza ndi mapeto, chubu chopanda kanthu chimakhala chopanda pang'onopang'ono, chomwe chimatchedwa chitoliro chachikulu. Kenako imatumizidwa ku makina odzigudubuza okha kuti apitilize kugudubuza. Pomaliza, makulidwe a khomawo amafananizidwa ndi makina ojambulira, ndipo kukula kwake kumatsimikiziridwa ndi makina owerengera kuti akwaniritse zofunikira. Kugwiritsa ntchito mayunitsi opitilira chitoliro kuti apange mapaipi achitsulo osasunthika otentha ndi njira yotsogola.

1.2. Ngati mukufuna kupeza mapaipi opanda msoko okhala ndi makulidwe ang'onoang'ono komanso abwinoko, muyenera kugwiritsa ntchito kugudubuza kozizira, kujambula kozizira, kapena kuphatikiza ziwirizi. Kuzizira kozizira nthawi zambiri kumachitika pa mphero ziwiri, ndipo chitoliro chachitsulo chimakulungidwa mu chiphaso cha annular chopangidwa ndi chozungulira chozungulira chozungulira ndi mutu wokhazikika. Kujambula kozizira nthawi zambiri kumachitika pamakina a 0.5 mpaka 100T amodzi kapena makina ojambulira ozizira awiri.

1.3. The extrusion njira ndi kuika mkangano chubu akusowekapo mu chatsekedwa extrusion yamphamvu, ndi perforation ndodo ndi extrusion ndodo kusuntha pamodzi kuti extrusion mbali extruded kuchokera yaing'ono kufa dzenje. Njirayi imatha kupanga mapaipi achitsulo okhala ndi ma diameter ang'onoang'ono.

2. Kugwiritsa ntchito mapaipi achitsulo opanda msoko

2.1. Mipope yopanda msoko imagwiritsidwa ntchito kwambiri. Mapaipi opanda msokonezo amakulungidwa kuchokera ku chitsulo chopangidwa ndi mpweya wamba, chitsulo chochepa cha alloy structural chitsulo, kapena chitsulo chopangidwa ndi aloyi, chomwe chimakhala chachikulu kwambiri, ndipo amagwiritsidwa ntchito makamaka ngati mapaipi kapena zida zonyamulira madzi.

2.2. Amaperekedwa m'magulu atatu malinga ndi ntchito zosiyanasiyana:

a. Amaperekedwa molingana ndi kapangidwe kake ndi makina;

b. Amaperekedwa molingana ndi makina;

c. Amaperekedwa molingana ndi hydraulic pressure test. Ngati mapaipi achitsulo omwe amaperekedwa molingana ndi magulu a ndi b amagwiritsidwa ntchito kupirira kuthamanga kwamadzimadzi, ayeneranso kuyesedwa kwa hydrostatic.

2.3. Mapaipi opanda msoko amaphatikizapo mapaipi opanda msoko a ma boilers, mapaipi opanda msoko a geology, ndi mapaipi opanda msoko a petroleum.

3. Mitundu ya mipope yachitsulo yopanda msoko

3.1. Mipope yachitsulo yopanda msoko imatha kugawidwa m'mapaipi otentha, mipope yozizira, mipope yozizira, mipope yotulutsa, etc. malinga ndi njira zosiyanasiyana zopangira.

3.2. Malinga ndi mawonekedwe ake, pali machubu ozungulira ndi machubu apadera. Kuphatikiza pa machubu masikweya ndi machubu amakona anayi, machubu owoneka bwino amaphatikizanso machubu oval, machubu ozungulira, machubu atatu, machubu a hexagonal, machubu owoneka ngati ma convex, machubu owoneka ngati maula, ndi zina zambiri.

3.3. Malinga ndi zipangizo zosiyanasiyana, iwo amagawidwa mu mapaipi wamba mpweya structural, mapaipi otsika aloyi structural, mapaipi apamwamba mpweya structural, mapaipi aloyi structural, mapaipi zitsulo zosapanga dzimbiri, etc.

3.4. Malinga ndi zolinga zapadera, pali mapaipi otenthetsera, mapaipi a geological, mapaipi amafuta, ndi zina zambiri.

4. Mafotokozedwe ndi maonekedwe a mipope yachitsulo yopanda msoko ndi GB/T8162-87.

4.1. Kufotokozera: The awiri akunja chitoliro otentha adagulung'undisa ndi 32 ~ 630mm. Khoma makulidwe 2.5 ~ 75mm. The awiri akunja ozizira adagulung'undisa (ozizira kukopedwa) chitoliro ndi 5 ~ 200mm. Khoma makulidwe 2.5 ~ 12mm.

4.2. Maonekedwe abwino: Pakatikati ndi kunja kwa chitoliro chachitsulo sichiyenera kukhala ndi ming'alu, zopindika, zopindika, zolekanitsa, mizere yatsitsi, kapena zipsera. Zowonongeka izi ziyenera kuchotsedwa kwathunthu, ndipo makulidwe a khoma ndi m'mimba mwake akunja sayenera kupitirira zolakwika zolakwika pambuyo pochotsa.

4.3. Mapeto onse a chitoliro chachitsulo ayenera kudulidwa molunjika ndipo ma burrs ayenera kuchotsedwa. Mapaipi achitsulo okhala ndi khoma lokulirapo kuposa 20mm amaloledwa kudulidwa ndi kudula gasi ndi macheka otentha. N'zothekanso kuti musadule mutu pambuyo pa mgwirizano pakati pa maphwando opereka ndi ofunikira.

4.4. "Mawonekedwe apamwamba" a mapaipi achitsulo omwe amakokedwa kapena kuzizira bwino amatanthawuza GB3639-83.

5. Kuyang'anira kapangidwe ka mankhwala a mipope yachitsulo yopanda msoko

5.1. The mankhwala zikuchokera m'nyumba mipope yopanda msoko kuperekedwa malinga ndi mankhwala zikuchokera ndi katundu makina, monga No. 88. Mipope yopanda msoko yotumizidwa kunja imawunikiridwa molingana ndi mfundo zomwe zafotokozedwa mu mgwirizano. Mankhwala a 09MnV, 16Mn, ndi 15MnV zitsulo ayenera kutsatira malamulo a GB1591-79.

5.2. Kuti mupeze njira zenizeni zowunikira, chonde onani magawo ofunikira a GB223-84 "Njira Zowunikira Mankhwala a Zitsulo ndi Aloyi".

5.3. Pazopatuka zowunikira, onani za GB222-84 "Kupatuka kovomerezeka kwa mankhwala a zitsanzo ndi zinthu zomalizidwa pakusanthula mankhwala achitsulo".
