API 5L X70 mzere wopanda chitsulo chitoliro

API 5L X70 chitoliro ndi premium giredi mipope zinthu mu API 5L specifications muyezo. Imatchedwanso L485 chitoliro, chifukwa ndi mphamvu zokolola
osachepera mu 485 Mpa (70,300 psi). API 5L X70 imakwirira mitundu yopanga mumitundu yopanda msoko ndi yowotcherera (RW, SAW), yonse yogwiritsidwa ntchito
zotumizira mafuta ndi gasi.

API X70 mpweya zitsulo mzere chitoliro angatanthauzidwe ngati zitsulo chitoliro ndi mkulu mpweya okhutira ndi aloyi pawiri. API 5L X 70 carbon steel seamless chitoliro Kuphatikiza pa kufufuza zinthu zina monga sulfure, phosphorous, ndi zina zotero, alloy yake imakhala ndi manganese ndi silicon. Kuwonjezera zinthu zonsezi kumathandiza kusintha makina katundu X70 mpweya zitsulo chitoliro.

Izi zitha kuwoneka kuchokera ku mphamvu yotsika (485 MPa) ya API 5L X70 Kalasi B LSAW chubu. Ilinso ndi mphamvu yocheperako ya 635 MPa. Pamwamba pa machubu a API 5L X70 SCH 40 DSAW amathandizidwa m'mitundu yosiyanasiyana, monga mafuta akuda, anticorrosive, galvanized otentha kapena ozizira. Kutengera kagwiritsidwe ntchito ka X70 PSL2 spiral chubu, titha kupangira chithandizo chapamwamba chapamwamba kwa makasitomala athu olemekezeka. Mwachitsanzo, zokutira malata pa X70 PSL1 giredi mapaipi amasonyeza kukana dzimbiri.
