Tareenka Tareenka leh vs. Xadiidka Tareenka Helical: Isbarbardhigga 7-cabbirka ugu dambeeya

Thedarajada alaabta ceeriiniyohabka wax soo saarkasi toos ah u go'aamin cimri dhererka sare. Ourcaaradau hoggaansamaan heerarka GB/T 700 iyo TB/T 3395, hubinta joogtaynta mashaariicda tareenada caalamiga ah.

Jidadka tareenada casriga ah waxay isticmaalaan agabyo kala duwan, oo ay ku jiraanisku dhafan, biriyohurdayaasha shubka ah ee prepressed. Saxdataraarka tareenkawaa in ay la jaanqaadaan walxaha hurdada. Had iyo jeer kala tasho tafaasiisha soo saaraha ee codsiyada aan caadiga ahayn{{1}

Talada Pro: Dhiirrigelintu aad bay waxtar ugu leedahay hurdayaasha alwaaxda sidoo kale, laakiin aGodka duuliyaha ee horay loo qoday -waa lama huraan si looga hortago dildilaaca alwaaxda iyo in la hubiyo ka qaybgalka dunta saxda ah.

Odhaahda "qiimihiisu jaban yahay si aad u iibsato ≠ raqiis in aad leedahay" waa runqalabka tareenka. Iyadoo dunta dunta leh ay leeyihiin qiime hoose oo bilaw ah, waxay inta badan u baahan yihiin bedel iyo dayactir joogto ah.

Jawaab celinta macmiilka: "Markaan u gudubnay xadhkaha goos gooska ah ee khadkayaga macdanta Afrika, waxaan awoodnay inaan hoos u dhigno kharashyada dayactirka wadada sanadlaha ah 35% cajiib ah." - Maareeyaha Mashruuca, Qandaraaslaha EPC ee Shiinaha

Qandaraasyada suuqyada soo koraya ayaa si isa soo taraya u qeexaya "soo saar - Ka weyn ama la mid ah 100kN", taasoo ka dhigaysa xariijimo helical ahheerka dhabta ah.
