Chemical Raw Material Transportation

Scenario 2: Chemical Raw Material Transportation (Suitable for Solvent/Batching Projects)

1. Core Requirements & Product Selection

 Corrosion Resistance Adaptation Key: Corrosion-resistant fittings and leak-proof valves are required for chemical raw materials (ethanol, solvents). We integrate resources from over 4 anti-corrosion fitting manufacturers in China. Regular models (carbon steel + PTFE coating, DN40–DN125) are in sufficient stock and ship within 10 days. For transporting highly corrosive media (e.g., concentrated hydrochloric acid), we can coordinate 30-day customized full PTFE-lined models with Chinese manufacturers and provide medium immersion test reports to ensure safety.

 Product Specification Matching:

---Batching Branch Connection: DN40–DN65 anti-corrosion threaded fittings (elbows, straight joints, suitable for small-flow batching). Chinese manufacturers uniformly produce coating thickness ≥0.2mm.

---Main Transportation Line Connection: DN80–DN125 anti-corrosion flange fittings (suitable for large-flow transportation).

---Valve Selection: PTFE-lined ball valves (DN40–DN65) for batching (precise batching control); PTFE-lined gate valves (DN80–DN125) for main lines (corrosion-resistant sealing). Based on medium corrosion levels, we match Chinese manufacturers with different anti-corrosion grades to provide cost-effective solutions.

 Safety Assurance: Fittings require anti-static grounding during installation (1 grounding electrode per 50m). Chinese manufacturers provide grounding installation diagrams to assist your team in avoiding static risks.

2. Construction & Acceptance Standards

 Installation Specifications:

---Inspect coating integrity of fittings before installation (coating test pens included with shipments) to avoid transportation damage.

---Use anti-corrosion gaskets (PTFE material) for valves; apply anti-seize agent to bolts (sourced from Chinese chemical manufacturers) to avoid disassembly difficulties later.

 Key Acceptance Indicators:

---Sealing Test: Maintain 0.8MPa water pressure for 24 hours with no leakage.

---Anti-static Test: Pipe grounding resistance ≤10Ω (procurement channels for grounding resistance testers provided). We provide anti-static acceptance case references from Chinese chemical projects to support your project.

3. Common Issues & Solutions

· Issue 1: Fitting coatings peel due to long-term solvent immersion.

Solution: Regularly test coating thickness (once every 3 months, coating thickness gauge rental service provided); touch up damaged areas with anti-corrosion paint (sourced from Chinese manufacturers, 5% cost increase). For thicker coatings, 30-day customization can be coordinated to adjust coating processes.

· Issue 2: Batching flow control is imprecise.

Solution: Install "flow metering fittings" after valves (sufficient stock from Chinese manufacturers, 30% more expensive than regular fittings). For flow feedback functions, 30-day customization can be coordinated with Chinese manufacturers to integrate flow sensors for precise control.
