Industrial Natural Gas Transportation

Scenario 2: Industrial Natural Gas Transportation (Suitable for Factory Workshop Projects)

1. Core Requirements & Product Selection

 High-pressure Key: High-pressure-resistant fittings and high-seal valves are required for industrial transportation. We integrate resources from over 2 forged natural gas fitting manufacturers in China. Regular models (forged carbon steel, pressure resistance ≥25kg, DN65–DN150) are in sufficient stock and ship within 10 days. For linkage with industrial metering equipment (e.g., valves with flow signal output), we can coordinate 30-day customization with Chinese manufacturers and provide signal test reports for data synchronization.

 Product Specification Matching:

Workshop Branch Connection: DN65–DN80 forged threaded fittings (suitable for workshop gas use). Chinese manufacturers produce uniform forging processes with high strength.

Factory Main Line Connection: DN100–DN150 forged flange fittings (suitable for large-flow transportation, flange sealing surfaces with high-pressure natural gas gaskets).

Valve Selection: High-pressure natural gas ball valves (DN65–DN80) for workshops (pressure resistance ≥30kg); high-pressure natural gas gate valves (DN100–DN150) for main lines (resistant to frequent opening/closing). Based on industrial gas equipment pressure, we match Chinese manufacturers with corresponding pressure grades to ensure compatibility.

 Material Assurance: Fittings are uniformly made of 20# carbon steel (yield strength ≥245MPa). Chinese manufacturers conduct high-pressure tests for each batch and provide test reports.

2. Construction & Acceptance Standards

 Installation Specifications:

Secure high-pressure fittings to independent brackets (spacing ≤4m); tighten flange bolts diagonally to 100–120N·m (torque parameter table provided).

Ground valves for anti-static protection (avoids static ignition); install with arrow direction aligned with medium flow. We provide installation videos from Chinese industrial natural gas pipe projects for your team’s reference.

 Key Acceptance Indicators:

High-pressure Test: Maintain 1.5x working pressure (37.5kg) for 1 hour with no leakage.

Air Tightness Test: Maintain 0.15MPa air pressure for 24 hours with no leakage. We provide acceptance reports from Chinese industrial natural gas projects to support your project.

3. Common Issues & Solutions

· Issue 1: Fitting interface leakage due to high vibration in industrial environments.

Solution: Use "shockproof flange fittings" (sufficient stock from Chinese manufacturers, 15% more expensive than regular models, with built-in shockproof gaskets); or install "shockproof brackets" at pipe bends (sourced from Chinese bracket manufacturers, 8% cost increase) to reduce vibration impact.

· Issue 2: Valve cores freeze in low temperatures in winter.

Solution: Select "high-pressure valves with heating jackets" (30-day customization, 30% cost increase). Coordinate with Chinese electric heating manufacturers to supply heating jackets for winter electric heating; or wrap valves with insulation cotton (procurement channels for insulation cotton provided) for low-cost anti-freezing.
