(1) mapaipi esimbi ane dhayamita dzakasiyana anogona kugadzirwa nekushandisa simbi ine upamhi hwakaenzana, kunyanya mapaipi esimbi ane dhayamita hombe anogona kugadzirwa nesimbi yakamanikana.
(2) Pasi pemamiriro akafanana ekumanikidzwa, kumanikidzwa kwe spiral weld kudiki pane kwe straight weld, inova 75% ~ 90% ye straight weld pipe, saka inogona kutsungirira kumanikidzwa kukuru. Kana ichienzaniswa ne straight weld pipe ine dhayamita rekunze rakafanana, ukobvu hwemadziro hunogona kuderedzwa ne10% ~ 25% pasi pe pressure imwechete.
(3) Zviyero zvacho zvakarurama, kazhinji kukwirira kwedhayamita kuri pasi pe0.12%, kutsauka kuri pasi pe1/2000, uye ovality iri pasi pe1%, saka maitiro ehukuru nekutwasanudza anogona kusiyiwa.
(4) Kugadzirwa kunoramba kuripo kunogoneka. Mupfungwa, mapaipi esimbi akareba zvisingaverengeki anogona kugadzirwa. Kurasikirwa kwemusoro nemuswe wekucheka kudiki, uye mwero wekushandiswa kwesimbi unogona kuwedzerwa ne6% ~ 8%. (5) Kana ichienzaniswa nepombi yakasungirirwa yakatwasuka, inochinjika pakushanda, uye iri nyore pakuchinja mhando uye kugadzirisa.
(6) Huremu hushoma hwemidziyo uye mari shoma yekutanga inoshandiswa. Inogona kugadzirwa kuita mayuniti ekufambisa emhando yetrailer kuti igadzire zvakananga mapaipi akasungirirwa panzvimbo yekuvaka uko mapaipi akaiswa.
(7) Zviri nyore kuita kuti michina ishande uye ishande otomatiki.
Pombi dzakasungirirwa dzakaita sespiral dzinonyanya kushandiswa muinjiniya yemvura yepombi, indasitiri yepetrochemical, indasitiri yemakemikari, indasitiri yemagetsi, kudiridza kwekurima nekuvaka maguta muChina. Dzinoshandiswa pakufambisa mvura: kupa mvura nekudhonza mvura. Pakufambisa gasi: gasi remarasha, utsi negasi repetroleum rakanyungudutswa. Dzinoshandiswa sechivakwa: dzinoshandiswa sepombi dzinofambisa mapuranga nemabhiriji; Mapombi echiteshi chengarava, migwagwa nezvivakwa, nezvimwewo.
Kushandiswa
Sezvo makambani makuru eChina ari kutungamira muindasitiri yezvinhu zvesimbi, kutengeserana kwesimbi kwenyika yese uye logistics "zana rakanaka rebhizinesi", makambani ekutengesa simbi eChina, "Makambani epamusoro zana epachivande muShanghai". Shanghai Zhanzhi industry Group Co., Ltd., (yakapfupikiswa kuZhanzhi Group) inotora "Kuvimbika, Kushanda, Kugadzira Zvinhu Zvitsva, Kukunda-Kukunda" senzira yayo yega yekushanda, inogara ichienderera mberi nekuisa zvinodiwa nevatengi pakutanga.
