Code of inspection based on risk of complete sets of equipment
Part 1. Ethylene plant
1 Scope
This part of GB/T 33578 gives the risk-based inspection (RBI) implementation details for ethylene units.
This part applies to the superheated steam dilution tube furnace cracking method, the order of separation process-based ethylene plant in the implementation of the RBI items
The purpose of the pressure equipment, pre-deethane and de-propane process of ethylene plant can refer to the use.
This part does not apply to safety valves, safety valve inspection strategy see GB/T 26610.2.

3 terms and definitions
The terms and definitions defined in GB/T 26610.1 to 26610.5 and GB/T 30579 apply to this document.
4 General
4.1 This part is based on GB/T 26610.1 ~ 26610.5 and GB/T 30579, for the typical petrochemical plant - ethylene
The installation of the equipment, equipment characteristics of the test rules. This part does not replace the risk assessment work, but GB/T 26610.2 specific
The application of the device.
4.2 This part of the ethylene plant in the process to determine the potential damage to the equipment on the basis of damage to the model, given the key equipment and its special
The test method of the remaining equipment based on the damage pattern is determined according to GB/T 26610.2.
4.3 The damage pattern of the ethylene plant described in this section is determined by its typical materials, typical process conditions, and is likely to cause potential damage. real
The specific damage pattern of the ethylene plant should be adjusted according to the actual situation. In order to allow the user to distinguish between primary and secondary, this part is based on injury
Mode analysis and practical experience, according to the severity of the injury pattern and frequency, the damage model is further divided into the main damage mode
And secondary damage patterns.
4.4 The potential damage modes of the pressurized equipment in this section are given under normal operating conditions, under normal conditions or other special conditions (eg
Load, low load, raw material composition changes, ultra-designed) damage patterns and risk-based inspection rules determined by the actual situation.
4.5 inspection process found in the damage mode, the inspection staff should be based on the extent and extent of damage to determine whether the need for inspection. Inspection process
The defects are dealt with according to the relevant standards.
4.6 Atmospheric corrosion (including no insulation and thermal insulation) for the carbon steel and low alloy steel equipment, the prevalence of damage patterns, test methods
