Spiral welded steel pipe

Spiral welded zitsulo chitoliro amadziwikanso kuti ozungulira zitsulo chitoliro ndi kozungulira welded chitoliro, amene ntchito otsika mpweya structural zitsulo kapena otsika aloyi zitsulo Mzere malinga ndi ngodya ya mzere wozungulira (wotchedwa kupanga ngodya) adagulung'undisa mu chubu, ndiyeno chubu welded pamodzi anapanga, kungakhale yopapatiza Mzere kupanga lalikulu m'mimba mwake zitsulo chitoliro.Koyiloyo imagwiritsidwa ntchito makamaka pamapaipi amafuta ndi gasi, mawonekedwe ake OD * makulidwe a khoma.Kuwotcherera mbali ndi mbali ziwiri kuwotcherera kozungulira kozungulira chitoliro kuyenera kuonetsetsa kuti mayeso a hydrostatic, mphamvu yamakomedwe ya weld ndi kuzizira kopindika kumafunika.

(1) kuthamanga madzimadzi kufala ozungulira kumizidwa arc welded chitoliro: makamaka ntchito zonyamulira mafuta, gasi payipi;

(2) kuthamanga madzimadzi kufala mkulu pafupipafupi welded zitsulo mipope ndi ozungulira msoko: welded mkulu pafupipafupi lap kuwotcherera njira kuthamanga madzimadzi kufala ozungulira mkulu pafupipafupi welded zitsulo chitoliro.Luso la chitsulo chitoliro pansi pa mavuto, plasticity wabwino, chomasuka kuwotcherera ndi akamaumba ndondomeko;

(3) otsika kuthamanga madzimadzi kufala ozungulira kumizidwa arc welded zitsulo chitoliro: awiri amaganiza basi kumizidwa arc kuwotcherera kapena limodzi mbali imodzi kuwotcherera mu dongosolo malamulo otsika kuthamanga madzimadzi monga madzi, mpweya, mpweya ndi nthunzi ndi kumizidwa Arc welded chitoliro.

Zopanda msokozitsulochitoliro

Makhalidwe amtundu wa chitoliro chopanda msoko:
1. Kuyesa kosasunthika kwa chubu: kuyesa kwa flattening, kuyesa kwamphamvu, kuyesa kwamphamvu, kuyesa kwamoto, kuyesa kuuma, kuyesa kwa metallographic, kuyesa kupindika, kuyesa kosawononga (kuphatikiza eddy pano X-ray ndi kuyesa kwa akupanga).

2.Seamless chitoliro kusanthula mankhwala: mankhwala zikuchokera zinthu kusanthula mankhwala, mankhwala zikuchokera kuti akwaniritse zofunika muyezo.

3.Kuthamanga kwa chitoliro chosasunthika ndi kuyesedwa kwa hydrostatic ndiko kukakamiza chubu kupita ku mayeso a hydrostatic, omwe samasunga kupanikizika komwe kumaperekedwa osachepera masekondi a 5, kuti asaulule, kuyesa kwanthawi zonse kwa hydraulic pressure pressure ndi 2.45MPa pressure P = 0.5MPAa.

4.Kuyesa kwa dzimbiri: chitoliro cha chitsulo chosagwira ntchito m'mafakitale molingana ndi malamulo okhazikika kapena mgwirizano pakati pa dzimbiri la mayeso okana chitoliro chachitsulo, palibe dzimbiri la intergranular.

Makhalidwe a chitoliro chopanda msoko
(1) m’mimba mwake ndi wocheperapo.

(2) Kulondola kwambiri kumatha kupanga zocheperako zosaphika.

(3) chitoliro chozizira chokoka chitsulo chokhala ndi mwatsatanetsatane kwambiri komanso khalidwe labwino.

(4) zitsulo chitoliro mtanda m'dera ndi zovuta.

(5) chitsulo chitoliro chapamwamba ntchito, ndi wandiweyani zitsulo.
