L245 waxaa loola jeedaa darajada birta ee loo isticmaalo tuubada LSAW (Longitudinal Submerged Arc Welded). L245 waa darajada API 5L, gaar ahaan darajada tuubada xariiqda. Waxay leedahay awoodda wax-soosaarka ugu yar ee 245 MPa (35,500 psi). Habka alxanka LSAW wuxuu ku lug leeyahay alxanka dhererka ah ee taarikada birta, iyo darafyada la jeexjeexay waxay muujinayaan in darafyada tuubooyinka la gooyay oo lagu diyaariyey gees jeexan si loo fududeeyo alxanka. Tilmaamaha "Madow rinjiyeysan" ayaa tilmaamaya in dusha sare ee tuubada lagu dahaadhay rinji madow si loogu ilaaliyo daxalka iyo ujeedooyinka qurxinta.
