ityhubhu yebhoyila ivuliwe kuzo zombini iziphelo kwaye icandelo elinomngxuma, ubude kunye ezijikelezileyo intsimbi enkulu, ngokutsho iindlela imveliso inokwahlulwa ibe umbhobho intsimbi ingenamthungo kunye umbhobho wentsimbi edityanisiweyo, ingcaciso umbhobho yentsimbi kunye nemilinganiselo jikelele (ezifana nobubanzi okanye ubude) kunye nobukhulu eludongeni, uthe ubungakanani bayo uluhlu lubanzi kakhulu, ukusuka kwi-capillary encinci ukuya kwiimitha ezininzi ububanzi, umbhobho omkhulu ububanzi.

Iityhubhu zentsimbi zingasetyenziselwa imibhobho, izixhobo ezishushu, ishishini koomatshini, ukuhlola i-petroleum geological, izitya, ishishini lemichiza kunye neenjongo ezikhethekileyo.

(1) Umgangatho ophezulu we-carbon structural steel steel 20G, 20MnG, 25MnG.

(2) I-alloy structure steel 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, njl.

Ibhobho yebhoyila yohlulwe yangamacandelo amabini:GB/T3087-2018ityhubhu yebhoyila yoxinzelelo oluphakathi kunye noxinzelelo oluphantsi,GB/T5310-2018ityhubhu yebhoyila yoxinzelelo oluphezulu. Iimveliso zethu eziphambili ziquka:

I-ASTMA210(A10M)-2012Ibhoyila yentsimbi yekhabhoni ephakathi kunye nombhobho wentsimbi ongenamthungo, eyona nto iphambili yi-SA210 GrA1, SA210GrC;

ASME SA106/SA-106M-2015, izinto eziphambili ziyi-GR.B gr.C;

ASME/SA SA – 213-213 – m, izinto eziqhelekileyo ze-alloy: T11, T12, T22 kunye neT23, T91, P92, T5, T5b, T9, T21, T22, T17;

I-ASTM A335 / A335M - 2018, izixhobo eziphambili zezi: P11, P12, P22, P5, P9, P23, P91, P92, P2, njl.
