Kusiyana kwakukulu kwa iwo ndi chigongono chachifupi kuposa chopindika, R = 1D mpaka 2D ndi chigongono, Kuposa 2D kupindika. Chitoliro m'zigongono ndi chitoliro anaŵerama ndi onse wamba mankhwala chitoliro zovekera amene ntchito kusintha malangizo ikuyenda mu kachitidwe piping. Nthawi zina amasinthana, koma osafanana.
Zitsulo-Chigongono-45-Digirii-90-Digiri
Kupindika kwa chitoliro kumatanthauza chidutswa cha chitoliro chomwe chimayikidwa mbali zina kuti agwirizane ndi maipi awiri. atha kukhala pafupifupi utali wonse wopendekera ndi ma ngodya. Mapangidwe a chitoliro amapangidwa nthawi zambiri pamalopo kuti akwaniritse zosowa zina mwa kupindika kapena kutentha kozizira. Chigongono chimatanthawuza kupindika kwa chitoliro malinga ndi muyezo wa ANSI / ASME B16.9 (kapena EN 10253, kapena miyezo ina yazitsulo). Kawirikawiri zigongono zimakhala ndi utali wopindika wa 1.5D kapena 1D (Apa D amatanthawuza dzina laling'ono lamtunduwu), omwe amatchedwa "Long Radius elbow (LR elbow)" kapena "Short Radius elbow (SR chigongono)". ndipo mbali ya chigongono imakhala 45 digiri kapena 90 digiri nthawi zambiri, nthawi zina pamakhalanso zigongono zopangidwa mwaluso zomwe zimakhala 30 digiri, 60 degree, 180 degree kapena ma angles ena.
Chitoliro-Bend
Mayiko chitoliro akhale monga pa muyezo wa ANSI / ASME B16.49 amene sanali mwachindunji utali wozungulira kupinda ndi ngodya, zonse chitoliro unakhota utali wozungulira ndi 2.5D, 3D, 5D, 7D kapena 8D, koma kungakhale ina kupinda utali wozungulira malinga ndi kapangidwe kake, ndi ngodya yopindika ikhoza kukhala pamlingo uliwonse, 5, 10, 15, 90 digiri kapena ina iliyonse. Anthu adati "Kupindika konse ndi magoli koma zigongono zonse sizopindika", sizowona. Kwenikweni "Zigongono zonse ndizopindika koma sizokhotakhota zonse ndizigongono" ndizomveka.
