Umbhobho webhoyila uvulekile kuzo zombini iziphelo kwaye unecandelo elinomngxuma, ubude kunye nokujikeleza kwentsimbi enkulu, ngokweendlela zemveliso inokwahlulwa ibe ngumbhobho wentsimbi ongenamthungo kunye nombhobho wentsimbi odityanisiweyo, ukucaciswa kombhobho wentsimbi kunye nemilinganiselo jikelele (efana ne ububanzi okanye ubude) kunye nobukhulu bodonga, uthe uluhlu lwalo lobungakanani lubanzi kakhulu, ukusuka kwi-capillary encinci ukuya kwiimitha ezininzi ububanzi, umbhobho omkhulu wedayamitha.

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;
