Exhaust Pipe

Description

Parameter / Process	Specification & Technical Highlights	Customer Benefits / Value
Material	Grade 316 Stainless Steel (CF8M / 1.4408)	Provides exceptional resistance to chloride-induced pitting and acidic exhaust condensates, ensuring long-term rust-free operation.
Application Scenario	Automotive Field / Six-Cylinder Performance Engines / Exhaust & Fluid Pipelines	Perfectly engineered to endure aggressive gas flow and external environmental corrosive factors (such as road salt).
Unit Weight	9.72 kg (Heavy-Duty Precision Scale)	Demonstrates strong casting capabilities in pouring heavy, large-scale components with zero shrinkage.
Tooling Design	Advanced Split Design	The mold exterior and interior cavity utilize a tailored split design, guaranteeing accurate dimensions for complicated multi-bend paths.
Core Technology	Water-Soluble Core Molding for wax pattern pressing	Enables the formation of seamless long-through holes, delivering smooth interior walls that eliminate turbulence and maximize engine power.
Pouring System	Multi-Gate Gating System	Masterfully counteracts shell-making complexity; multi-gate filling ensures smooth liquid steel routing and eliminates subsurface porosity.
Casting Tolerance	ISO 8062 (GB/T6414) CT6 Grade	High near-net-shape accuracy simplifies final CNC machining and ensures perfect cylinder-to-flange alignment.

To survive the rigorous demands of automotive performance systems, every single batch undergoes elite validation:

Long-Through Hole Clearance Check: 100% video-endoscope verified to ensure all multi-bend channels are entirely clear, with absolutely zero water-soluble core residues or slag inclusions.
Dimensional & Flange Planarity (CMM): Inspected using Coordinate Measuring Machines to verify the critical true position of exhaust ports, avoiding layout warping across the long manifold structure.
Material Chemical Analysis: Verified via Spectrometers to ensure exact 316/CF8M chemistry (with correct Chromium, Nickel, and Molybdenum levels) for maximum anti-corrosion properties.
Micro-Defect NDT Screening: Processed via Liquid Penetrant Testing (LPT) to guarantee all heavy-duty joints and internal radiuses are free from microscopic thermal cracks.

Complex Multi-Cylinder Blueprint Customization: We specialize in casting performance exhaust components (4-cylinder, 6-cylinder, V8) and turbo-related segments based on your 3D digital data (STEP, IGES).
Flexible Surface Post-Treatments: Standard shot-blasting, uniform acid passivation (for an extra anti-corrosion barrier), or sandblasting are available based on your blueprints.
Audit-Ready Verification: Full material test certificates (EN 10204 3.1) and detailed CMM dimension sheets are supplied standard to support your Tier-1 automotive quality gating.
