Umbhobho we-API 5L X70 yimathiriyeli ye-premium grade piping in API 5L imilinganiselo esemgangathweni. Ikwabizwa ngokuba ngumbhobho we-L485, njengoko ingamandla emveliso
ubuncinane kwi-485 Mpa (70,300 psi). I-API 5L X70 igubungela iintlobo zokuvelisa ngokungenamthungo kunye neentlobo ezidityanisiweyo (ERW, SAW), zombini zisetyenziswa
ukuhanjiswa kweoli kunye negesi.
I-API X70 ye-carbon steel line pipe ingachazwa njengombhobho wensimbi onomxholo ophezulu wekhabhoni kunye ne-alloying compound. I-API 5L X 70 ibhobho ye-carbon steel seamless pipe Ukongeza kwimilinganiselo yokulandelela ezinye izinto ezifana nesulfure, i-phosphorus, njl., i-alloy yayo inomxholo ophezulu we-manganese kunye ne-silicon. Ukongezwa kwazo zonke ezi zinto kunceda ukuphucula iimpawu zemishini ye-X70 carbon steel pipe.
Oku kunokubonwa kumandla esivuno esiphantsi (485 MPa) ye-API 5L X70 Class B LSAW tube. Kananjalo inamandla obuncinci be-tensile ye-635 MPa. Umphezulu we-API 5L X70 SCH 40 DSAW iityhubhu ziphathwa kwiindidi ezahlukeneyo, ezifana nomnyama, ioli ye-anticorrosive, i-hot-dip galvanized okanye ibanda-galvanized. Kuxhomekeke kusetyenziso olukhethekileyo lwe-X70 PSL2 spiral tube, sinokucebisa olona nyango luphezulu kubathengi bethu abahlonitshwayo. Umzekelo, ukugquma kwegalvanized kwimibhobho yodidi lwe-X70 PSL1 kubonisa ukuxhathisa okugqwesileyo komhlwa.
