Integrated Engineering & Installation

Conventionally installed aboveground, the LPG residual liquid storage tank demands a seamless, integrated construction blueprint that unifies civil foundations, tank farm layouts, and piping networks.

Civil Foundation & Engineering: Custom-engineered based on tank dimensions, equipment loads, and site soil bearing capacity. It optimizes maintenance clearance, strategically integrates valve manifolds, and strictly adheres to fire safety separation distances.
Anti-Corrosion Protection: The outdoor coating system is meticulously matched to the site’s environmental corrosivity. For high-humidity or highly corrosive environments, comprehensive coating standards and acceptance metrics are defined right at the design phase to guarantee long-term, rock-solid operational stability.
Upstream Coordination: Interfaces, valve manifolds, and piping routes for the residual system are planned holistically from day one, ensuring a flawless, one-time commissioning of the station.

Applications & Siting Standards

I. Core Application Scenarios

Residual liquid recovery systems paired with LPG cylinder filling stations.
Vent and blowdown recovery systems for LPG station valve manifolds and piping networks.
Drainage and recovery units for equipment maintenance and medium displacement in storage and distribution stations.

II. Siting & Layout Requirements

Strategic Proximity: Positioned preferentially adjacent to residual liquid collection points, pump rooms, or centralized valve manifold areas to facilitate smooth gravity flow and efficient pump suction.
Dual-Compliance: Siting simultaneously satisfies both equipment operational clearance and stringent fire safety separation distances.
The Operational Hub: It serves as the vital infrastructure to close the loop on station management—centralizing residual liquid containment and unifying outward transport disposal.

Compliance, Manufacturing & Quality Control

As a classified pressure vessel, the entire manufacturing and inspection lifecycle strictly adheres to codes and regulations:

Core Manufacturing Controls: Precise base material matching, flawless weld forming quality, high-accuracy tank geometry, and uncompromised reliability of all sealing structures.
NDT & Testing: Non-Destructive Testing (NDT) is executed on critical pressure-bearing welds per project specifications, followed by hydrostatic/pneumatic testing and full factory inspections driven by design documents.
Pre-Shipment Verification: Every unit undergoes a rigorous pre-shipment audit to verify process nozzle orientations, equipment markings, and pre-installed accessories.
Upstream Alignment: Nozzle configurations, accessory checklists, and As-Built documentation standards are aligned during the ordering phase, drastically streamlining on-site acceptance.
