Emhlabeni wamapayipi wezimboni, ukukhetha kwezinto zokwakha nezindlela zokwakha kungathinta kakhulu ukusebenza nokuphila kwensiza kohlelo. Eminyakeni yakamuva,Spiral Steel Pipekungenye yezinto ezintsha ezidonsele ukunakwa kakhulu. Akukhona ukuthi leli qhwa liqinile kuphela futhi lihlala isikhathi eside, linikeza nezinzuzo ezihlukile ezenza zilungele izinhlelo ezahlukahlukene ze-application, ikakhulukazi ezinhlelweni zegesi ezipaywe.
Ngaphambi kokuthi sisebenzise imininingwane yamapayipi ensimbi, kufanele siqonde ukuthi bayini nokuthi bakhiwa kanjani. Empeleni, la mapayipi enziwa yimichilo ye-welding yensimbi ndawonye ngendlela eqhubekayo, enomoya imfashini. Le ndlela yokwakha ihlukanisa amapayipi e-siam asezingeni eliphakeme emapayipi e-seam aqonde yendabuko. Ama-seams athulayo adala isibopho esiqinile phakathi kwemichilo yensimbi, okuholela epayipi eliqinile nelithembekile elingamelana nezingcindezi eziphakeme kanye nezimo ezingeqile.
Enye yezinzuzo eziphambili zepayipi lensimbi enonile lingamandla alo. Ubuchwepheshe be-welding we-welding buvumela ukucindezelwa ukuthi kusatshalaliswe ngokulinganayo ngobude bepayipi. Lokhu kusho ukuthi amapayipi angamelana nezingcindezi zangaphakathi eziphezulu ngaphandle kokuhluleka. Lesi sici sibaluleke kakhulu ezimbonini lapho ukuphepha nokuthembeka kubaluleke kakhulu, njengamafutha negesi, ukwelashwa kwamanzi nezinhlelo ze-HVAC.
Ngaphezu kwalokho, inqubo yokukhiqiza amapayipi eSpiral Seam ivumela ukuguquguquka okukhulu ngosayizi nobubanzi. Ngokungafani namapayipi endabuko, angadinga ukwenza ngokwezifiso okubanzi ukuze kufinyelelwe amadayimane amakhulu, amapayipi we-siam seam angakhiqizwa ngosayizi abahlukahlukene abanokulingana. Lokhu kuvumelana nezimo kwenza kube ukukhetha okuhle kwamaphrojekthi adinga ubukhulu noma angadinga ukwamukela ukwanda okuzayo.
Enye inzuzo ebalulekile yepayipi lensimbi ye-helical seam ukumelana nokugqwala. Uma ihlanganiswe kahle futhi igcinwe, la mapayipi angamelana nezimo ezinzima zezemvelo, kubandakanya ukuchayeka kumakhemikhali kanye nomswakama. Lokhu kuqina akugcini nje kuphela ngokunweba impilo yohlelo lwe-duct kodwa futhi kunciphisa izindleko zokulungiswa ngokuhamba kwesikhathi, okwenza kube yisixazululo esisebenza ngempumelelo yezimboni eziningi.
Ngaphezu kwezakhiwo zayo ezibonakalayo, ipayipi lensimbi ye-helical seam nayo linobungani bemvelo. Inqubo yokukhiqiza yenzelwe ukunciphisa imfucuza kanye nezinto zokwakha ezisetshenzisiwe zivame ukwenziwa kabusha ekugcineni komjikelezo wazo wokuphila. Lesi sici sokusimama siya ngokuya sibaluleke kakhulu njengoba izimboni zilwela ukunciphisa izintambo zazo zekhabhoni futhi zihambisane nemithetho yezemvelo eqinile.
Uma ucubungula ibanga elithile lensimbi elisetshenziswa epayipi lensimbi ye-helical seam, kubalulekile ukukhetha impahla efanele ukusetshenziswa okuhlosiwe. Amamaki ahlukene wensimbi anamandla ahlukile, ukumelana nokugqwala kanye nokushiswa. Isibonelo, ama-Steel-aqiniswe aphansi-alloy (HSLA) ajwayele ukusetshenziswa kuzinhlelo zokusebenza ezidinga izakhiwo ezithuthukisiwe zemishini, ngenkathi kukhethwe ama-sterainlen stecial for ukumelana kwawo okuhle kakhulu ezindaweni ezilimazayo ezindaweni ezilimazayo.
Ngokufigqiwe,umthungo we-HelicalAmapayipi ensimbi amelela intuthuko enkulu kubuchwepheshe bePipeline. Indlela yayo yokwakha eyingqayizivele, ehlanganiswe namandla ayo, ukuguquguquka kanye nokuphikiswa kokugqwala, kwenze ilungele izinhlelo eziningi zezicelo. Njengoba imboni iqhubeka nokuvela futhi ifune izixazululo ezisebenza nge-piping ezisebenza kahle nezinokwethenjelwa, amapayipi ensimbi anomusa azodlala indima ebalulekile ezinhlelweni zegesi ezizayo zepayipi nangale kwalokho. Noma ngabe uyakhiwa, ekwakheni, noma yimuphi omunye imboni ethembele ezinhlelweni ezinamandla zamapayipi, ukuqonda izinzuzo zepayipi lensimbi ye-helical seam ingakusiza wenze izinqumo ezinolwazi zephrojekthi yakho.
