Core Content of Refining Equipment and Safety Installation Specifications

Refining equipment and safety installation specifications are primarily divided into national/industry standards and on-site operational requirements, aiming to ensure equipment installation quality and production safety.

I. Core National and Industry Standards

1. Equipment Installation Standards

GB 50461-2008 Code for Construction Quality Acceptance of Petrochemical Static Equipment Installation Engineering: Specifies acceptance criteria for installation accuracy, welding quality, and pressure testing of static equipment such as towers, reactors, and storage tanks.

SH/T 3524-2007 Standard for Quality Inspection and Evaluation of Petrochemical Equipment Installation Engineering: Defines quality inspection items and acceptance indicators for rotating equipment (e.g., pumps, compressors) and static equipment.

GB 50231-2009 General Code for Construction and Acceptance of Mechanical Equipment Installation Engineering: Applies to general requirements for foundation construction, equipment positioning, and commissioning of various refining mechanical equipment.

2. Safety Standards

GB/T 44958-2024 Specification for Safety Management of Chemical Equipment: Covers safety management requirements for the entire lifecycle of equipment, from design and installation to operation and decommissioning.

SH 3505.2-1999 Technical Specification for Petrochemical Construction Safety: Sets strict rules for hazardous operations during installation, such as working at heights, hot work, and lifting operations.

GB 50075-2014 Safety Technical Specification for Petrochemical Equipment: Requires equipment to be equipped with safety facilities such as safety valves and explosion-proof instruments, which must be calibrated regularly.

3. Specialized Equipment Specifications

GB/T 51175-2016 Technical Specification for Refining Unit Flame Heating Furnace Engineering: Provides detailed requirements for the design, material selection, installation, and inspection of heating furnaces.

GB 150.1~4-2011 Steel Pressure Vessels: Specifies material selection, manufacturing, and installation requirements for pressure vessels, applicable to distillation kettles, reaction kettles, and other pressure-bearing equipment.

II. Key Requirements for On-Site Safety Installation

1. Pre-Construction Phase

Conduct safety education for operators; personnel working at heights must wear safety belts and work on qualified scaffolding.

Inspect the safety of machinery and tools to ensure lifting equipment, welding equipment, etc., meet safety standards.

2. Installation Process

Explosion Protection Requirements: Explosion-proof electrical devices and valves must be used in explosive hazard areas, and equipment installation spacing must comply with fire protection codes.

Fire Protection: Load-bearing steel frames of equipment with operating temperatures above the autoignition point must be fireproofed.

Sealing and Pressure Testing: Pressure-bearing equipment must undergo airtightness testing and pressure testing after installation to ensure no leaks.

3. Acceptance and Operation & Maintenance

All equipment must be inspected and accepted in accordance with standards after installation; critical components (e.g., safety valves) must be repressurized and sealed with lead.

Establish a regular equipment inspection system for daily maintenance of explosion-proof systems and fire protection facilities.
