Web7 Dec 2009 · Re: Dual Stencilling of API 5L Pipe (i.e. X42/X52) 12/05/2009 7:23 AM. The strength requirements for X42 are min. YS: 42,000 psi and min. UTS 60,000 psi, for X52 they are 52,000 and 66,000 psi. Thus it isn't exactly difficult to have a pipe which meets both requirements, and X46 (46,000 and 63,000 psi) as well!
