Product Description SA516Gr70+2205 Roll Bonded Clad Plate (6:1 Ratio) - Engineered for Sulfur Attack & Structural Integrity in Coker DrumsThe Ultimate Material Solution for Delayed Coker UnitsDesigned to withstand extreme operating conditions in coker drums - high-temperature sulfur corrosion, thermal cycling stress, and mechanical impact - our SA516Gr70+2205 duplex clad plate delivers revolutionary performance. This roll-bonded composite merges the pressure-bearing strength of carbon steel with the superior corrosion resistance of duplex stainless steel, creating a zero-defect metallurgical bond that eliminates cracking, thinning, and failure in critical coker equipment. Core Technology: Roll Bonding + Optimized 6:1 Ratio1. Roll Bonding Process AdvantagesSolid-State Metallurgical Bond: High pressure and temperature forge an atomic-level bond between SA516Gr70 base and 2205 cladding without filler metals.Uniform Interface: Seamless transition layer prevents delamination (ASTM A264 compliant).Cladding Integrity: Zero dilution preserves 2205 duplex chemistry and corrosion resistance.2. Engineered 6:1 Thickness Ratio Critical Value for Coker Drum Service Eliminates Sulfur-Induced FailuresResists 480°C sulfur compounds (H2S, RSH, S2), reducing wall thinning by 90% vs. carbon steel.Withstands naphthenic acid + sulfur synergy corrosion.Certified for sulfide stress cracking (SSC) immunity per NACE MR0175/ISO 15156. Conquers Thermal-Mechanical FatigueMatched thermal expansion coefficients (SA516Gr70: 12.5 μm/m·oC; 2205: 13.5 μm/m·oC) minimize thermal stress.High yield strength (2205: ≥450 MPa) prevents drum deformation. Withstands Decoking OperationsImpact-resistant interface endures 2500 psi hydroblasting.Controlled hardness (22-28 HRC) prevents hydrogen-induced cracking (HIC). Lifecycle Economics50% cost savings vs. solid 2205 duplex steel.3x longer service life (>25 years) vs. carbon steel (5-8 years).
