Schedule (SCH) is a dimensionless number designating wall thickness for a given nominal size. Higher schedule = thicker wall. Common: SCH 10, 40 (standard), 80 (XS), 160.
EN 10216 = seamless tubes. EN 10217 = welded tubes. Suffix -2 = carbon/alloy steel. Suffix -5/-7 = austenitic stainless steel.
Rp0.2 = 0.2% proof stress (yield) for carbon/alloy steels. Rp1.0 = 1.0% proof stress for austenitic stainless steels per EN standards. Both decrease with temperature.
Carbon steel: f = MIN(Rp0.2/1.5, Rm/2.4). Austenitic SS (A≥35%): f = MIN(Rp1.0/1.2, Rm/3). Per CODETI 2013 GA4/GA5.
Each EN material number is cross-referenced with its AISI designation, ASTM pipe/tube specification, and UNS number. Example: EN 1.4404 = AISI 316L = ASTM A312 TP316L = UNS S31603. Data sourced from Trouvay & Cauvin and verified against NF/DIN/AISI/ASTM/UNS standards. Search by any designation: type "316L", "P91", "S31603", or "1.4404" to find all matching grades.
For DN ≤ 250 (10"), yes. Above DN 250, SCH 40 gets thicker while 40S stays constant. Same for SCH 80 vs 80S.
