API 5L X65 (L450)ni umuyoboro wa API 5L w’icyuma giciriritse kugeza ku rwego rwo hejuru, witiriwe nibura yIngufu z'ubutaka za psi 65,300 (450 MPa).
Umuyoboro w'icyuma wa X65 ukunze gukoreshwa mu guhangana n'umuvuduko ukabije n'ibidukikije bikomeye, ukwiriye cyane imiyoboro ya peteroli na gazi aho bisaba kuramba no kwizerwa cyane. Byongeye kandi, imiterere yawo myiza ya mekanike no kudahura n'ingufu bituma uba mwiza cyane mu miyoboro yo munsi y'inyanja no mu nganda zikora ibintu byangiza cyane.

Icyiciro cya API 5L X65
Bitewe n'urwego rwa PSL n'uko imodoka ihagaze, X65 ishobora gushyirwa mu byiciro bikurikira:
PSL1: X65 (L450);
PSL2: X65Q (L450Q) na X65M (L450M);
Kugira ngo habeho guhangana n’imimerere mibi yo mu nyanja (O) n’ibidukikije bito bya serivisi (S), ibipimo ngenderwaho bya API 5L PSL2 bifite ibisabwa byihariye kuri ibyo bidukikije byombi. Ibi bisabwa bigaragazwa no kongeramo inyuguti yihariye ku gipimo cy’umuyoboro.
Serivisi zo mu mazi umuyoboro wa PSL2:X65QO (l450QO) cyangwa X65MO (L450MO);
Umuyoboro wa PSL2 utanga serivisi nziza:X65QS (L450QS) cyangwa X65MS (L450MS).
