Ipayipi lensimbi engenamthungo, elaziwa nangokuthi i-stainless steel seamless tube, iyisilinda ende engenalutho esetshenziselwa ukuhambisa uketshezi (uketshezi noma amagesi).
“Ipayipi elingenamthungo” kanye “neshubhu lensimbi engagqwali” acishe ashintsheke, nakuba umehluko omncane ukhona, ngokuvamile, ishubhu linezidingo zobunjiniyela eziqinile kunepayipi.
UCepheus ungumkhiqizi ochwepheshe okhethekile ekwenzeni amapayipi angenamthungo kumadiameter amakhulu, aphakathi nendawo namancane.
Amapayipi ahlukahlukene ensimbi engenamthungo akhiqizwa ngokucaciswa okuphelele kanye nekhwalithi ephezulu.
I-Cepheus inemishini emihle kanye nokuphathwa kwekhwalithi ephelele, isungula uhlelo lwesimanje lokuphatha ikhwalithi, yethula ubuchwepheshe obuthuthukisiwe emhlabeni wonke futhi isebenzisa indlela yokukhiqiza ethuthukile yamazwe ngamazwe.
Ipayipi lensimbi engenamthungo lisetshenziswa kabanzi ezimbonini ezifana ne-petroleum, imboni yamakhemikhali, imishini, amandla kagesi, i-chemical fiber, i-papermaking, ukuphrinta nokudaya, ukudla kanye nezingxenye zomoya njll.
Le nkampani ihlinzekwa ngemishini yokuhlola ephelele futhi yamukela izindinganiso zobuchwepheshe zemikhiqizo enjengale: ipayipi elingenamthungo lokuthuthwa kwamanzi, ipayipi elingenamthungo lokwakha, elingenamthungo kubhayela kanye nesishintshi sokushisa.
Ububanzi bangaphandle be-stainless stainless esikhiqizayo busukela ku-4.0mm kuye ku-1219mm. Ukuqina kodonga kungu-0.5mm kuya ku-100mm. Ngensimbi, sizimisele.

I-WT ubukhulu bodonga olushiwo
Amapayipi ensimbi engagqwali kufanele afakwe emanzini anosawoti ngaphandle kwesikali. Lapho kusetshenziswa i-annealing ekhanyayo, ukuqoqa akudingekile.
