1. Izimpawu zokuhweba nokuphrinta kwamashubhu ekhwalithi ephezulu kusezingeni uma kuqhathaniswa.

2. Ukubunjwa kwensimbi yekhwalithi ephezulu kuyiyunifomu, i-tonnage yomshini we-shear ebandayo iphezulu, futhi ubuso bokuphela kwekhanda lokusika bushelelezi futhi bujwayelekile. Kodwa-ke, ngenxa yezinto zokusetshenziswa ezimbi, ubuso bokugcina bekhanda lokusika lensimbi enesici ngokuvamile bubonakala bokulahlekelwa inyama, okungukuthi, ayilingani futhi ayinakho i-metallic luster. Futhi ngenxa yokuthi imikhiqizo yabakhiqizi bezinkuni abakhubazekile inamakhanda ambalwa, izindlebe ezinkulu zizovela ekhanda nasemsila.

3. Amapayipi ensimbi ezungezayo angasebenzi avame ukuba nezindawo ezinemigodi ezindaweni zawo. Ama-pockmark awalungile futhi awalingani endaweni yensimbi ebangelwa ukuguga okukhulu nokudabuka kwemisele eginqikayo. Ngenxa yokuthi abakhiqizi bamapayipi ensimbi avunguzayo aphansi bafuna inzuzo, ukugingqika kwe-groove ngokuvamile kubonakala kubiza kakhulu.

4. Ingaphezulu lamapayipi ensimbi avunguzayo anesici athambekele ekubeni nezibazi.

5. Ingaphezulu lokhuni olungasebenzi luvame ukuqhekeka ngoba impahla yalo eluhlaza i-adobe, enezimbotshana eziningi. I-adobe ingaphansi kokucindezeleka okushisayo phakathi nenqubo yokupholisa, okubangela imifantu, futhi imifantu ivele ngemva kokugingqika.

6. Amapayipi ensimbi agqinsile anezindonga ezinesici kulula ukuwanwaya. Isizathu siwukuthi abakhiqizi bamapayipi ensimbi okuvunguza anesici banemishini empofu futhi bathambekele ekubeni nama-burrs nemihuzuko ebusweni bensimbi. Imihuzuko ejulile emandleni ensimbi ewayo.

7. Amapayipi ensimbi ezungezayo angasebenzi awanakho ukucwebezela kwensimbi futhi anombala obomvu ngokukhanyayo noma afana nombala wensimbi yengulube.

8. Ngemicu emikhulu enobubanzi obungu-16 noma ngaphezulu kumapayipi ensimbi ethandelayo kathathu, ibanga phakathi kwezimpawu zokuhweba ezimbili lingaphezu kwe-IM.

9. Imigoqo yobude be-rebar yensimbi enesici ivamise ukuba namagagasi.

10. Abakhiqizi bamapayipi ensimbi ayi-spiral abadebesele ekupakisheni ngoba abanawo amaloli. uhlangothi oluyiqanda

11. Izimbambo ezivundlile zamapayipi ensimbi ezungezayo zincane futhi ziphansi futhi ngokuvamile zibonakala zingagcwali kakhulu. Isizathu siwukuthi ukufeza ukubekezelelana okukhulu okungalungile, ukunciphisa komkhiqizi ekudluleni kokuqala komkhiqizo kukhulu kakhulu, isimo sensimbi sincane kakhulu, futhi iphethini yembobo ayigcwaliswa.

12. I-cross-section of inferior spiral steel pipes is oval. Isizathu siwukuthi ukulondoloza izinto zokwakha, inani lokunciphisa lamaphasi amabili okuqala e-roller eqediwe likhulu kakhulu. Amandla alolu hlobo lwe-rebar ancipha kakhulu, futhi awahlangabezani nezindinganiso zokubukeka ze-rebar. izindinganiso.

13. Amapayipi ensimbi okuvunguzayo angalungile aqukethe ukungcola okuningi, ukuminyana kwensimbi kuncane, futhi ukubekezelela usayizi kubucayi, ngakho-ke kungakalwa futhi kuhlolwe ngaphandle kwe-vernier caliper.

14. I-diameter yangaphakathi yamapayipi ensimbi e-spiral ephansi iyashintshashintsha kakhulu.

15. Amapayipi ensimbi okuvunguza anephutha athambekele ekugoqeni. Ukugoqa kukhona imigqa egoqiwe ehlukahlukene eyakhiwe phezu kwamapayipi ensimbi asongekile. Lesi sici sivame ukugijima kulo lonke isiqondiso se-longitudinal yomkhiqizo. Isizathu sokugoqa ukuthi abakhiqizi abaphansi baphishekela ukusebenza kahle okuphezulu futhi ukunciphisa kukhulu kakhulu, kubangela izindlebe. Ukugoqa kwenzeka ngesikhathi sokugoqa esilandelayo. Umkhiqizo ogoqiwe uzoqhekeka ngemva kokugoba, futhi amandla ensimbi ayancipha kakhulu.
