Explosion-proof Body

Technical Specifications & Pressure-Containment Engineering

Rigorous Petrochemical-Grade Quality Assurance

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.

Custom OEM / ODM Engineering for Global Refinery Supply Chains

• 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.

Custom Explosion‑proof Body Investment Casting

This explosion‑proof body is presented as a representative custom‑manufactured component for Petrochemical equipment; Gas pipelines; Chemical refinery processing; Flow‑control manifolds; Instrumentation enclosures; Pump bodies Honyang Cast develops similar parts from customer drawings rather than offering a fixed catalog specification.

The manufacturing plan must connect the part's functional geometry—Pressure‑containing body; Bolt circles; Sealing grooves; Internal threads; Multi‑channel cavity examples—with tooling, investment casting, machining and measurable inspection requirements. Final dimensions, interfaces and acceptance criteria are confirmed during drawing review.

PROJECT‑SPECIFIC SUPPLY

Material grade, dimensions, tolerance zones, machining allowance, surface condition, operating requirements and inspection records are confirmed after review of the customer’s 2D drawing, 3D model and project specification.

Key Technical Parameters & Custom Specifications

The parameter set is selected for this component’s function. Unknown values remain drawing‑controlled and must not be replaced with generic catalog data.

Part Design & Structural Features

Manufacturing Process & Machining Plan

A project‑specific route is established after review of geometry, alloy, tolerance, volume and validation requirements.

1. Drawing and DFM review — identify functional interfaces, wall transitions, draft, machining allowance, datums and inspection access.
2. Tooling and pattern planning — develop the wax tooling, core strategy and pattern assembly method required by the approved geometry.
3. Investment casting — control wax pattern, ceramic shell, melting, pouring and solidification for the selected alloy and part geometry.
4. Shell removal and finishing — remove gating, clean the casting and prepare critical areas for inspection or machining.
5. CNC machining where required — machine sealing faces, bores, threads, holes or mounting interfaces defined by the drawing.
6. Final inspection and records — verify agreed characteristics and compile project‑required material, dimensional or NDT records.

PROCESS SCOPE

Investment casting and CNC machining are described as the core route. Heat treatment, coating, polishing, balancing, pressure testing, radiographic testing, PPAP or other special processes must be shown as project‑specific unless their scope is confirmed.

Custom Development Capability

Honyang Cast supports drawing‑based development of explosion‑proof body and related investment cast components from manufacturability review through sample approval and repeat production.

1. RFQ input — submit 2D drawing, STEP/IGES model, material, annual volume, operating conditions and critical characteristics.
2. DFM review — align casting feasibility, core or gating strategy, machining allowance, datum scheme and inspection approach.
3. Tooling and sample — develop tooling, produce initial samples and inspect agreed characteristics.
4. Customer approval — review samples, dimensions and records under the agreed approval process.
5. Production delivery — supply as‑cast, machined, finished or assembly‑ready parts according to the confirmed scope.
