Explosion-proof Body

Description

Parameter / Process	Specification & Technical Highlights	Customer Benefits / Value
Material	Grade 316 Stainless Steel (CF8M / 1.4408 Industrial Grade)	Delivers robust resistance to volatile hydrocarbons, acidic/alkaline chemicals, and chloride-induced stress corrosion cracking.
Application Scenario	Petrochemical Equipment / Gas Pipelines / Chemical Refinery Processing	Perfect for high-reliability flow control manifolds, specialized instrumentation enclosures, and severe-service pump bodies.
Unit Weight Range	1.617 kg / 2.368 kg (Available in Multiple Custom Specifications)	Offers standardized series matching or component-mating options for multi-part chemical valves and housings.
Pouring System	Advanced Multi-Gate Gating System	Carefully balanced melt routing ensures highly uniform thermal solidification, guaranteeing zero internal shrinkage porosity.
Leakage Defense	100% Mandatory Pressure Testing Required	Validates absolute material density and wall structural integrity under designated pressure ratings to prevent hazardous media leaks.
Casting Tolerance	ISO 8062 (GB/T6414) CT6 Grade	Superior dimensional repeatability over critical bolt circles and sealing grooves, ensuring perfect O-ring compression.
Surface Treatment	Precision Shot-Blasting & Acid Pickling	Enhances aesthetics while removing iron contamination to passivate the surface for superior corrosion protection.

Because petrochemical components must maintain infallible performance in hazardous environments, we execute a zero-defect quality protocol:

100% Leak & Pressure Integrity Test: Every single casting goes through rigorous pneumatic or hydrostatic pressure validation to guarantee absolute sealing performance under extreme operating pressure.
Subsurface Shrinkage Audit: Processed via Liquid Penetrant Testing (LPT) on major joint sections and gate connection points to confirm a 100% solid, flaw-free grain layout.
Sealing Groove Geometry Check (CMM): Inspected using high-end Coordinate Measuring Machines to verify that sealing faces, bolt positions, and internal thread alignments match your exact blueprint clearances.
Alloy Chemistry Spectrum Control: 100% validated via Spectrometers to guarantee proper Molybdenum (2.0–3.0%) content, critical for maintaining chemical-resistant passivity.

Complex Fluid Cavity Customization: We specialize in casting complex multi-channel valve houses, heavy-duty instrumentation covers, and explosive-proof enclosures based on your 3D digital technical data (STEP, IGES).
Fully Finished Machining Capability: Equipped with advanced CNC centers to deliver parts as-cast or ready-for-assembly with micron-level tolerance machining.
Traceable Compliance Packs: Complete material mill test certificates (EN 10204 3.1), NDT records, and pressure testing logs are provided with every industrial order.
