The selection of reciprocating pressure test pumps in accordance with API 674 standards ensures that equipment meets stringent safety and reliability requirements during pressure test operations in industrial piping systems, pressure vessels, and other pressurized systems.
1. Operating Conditions
First, clearly define the operating conditions. Analyze the required working pressure range and flow rate demands of the pressure test system, as these are the core parameters for pump selection. Additionally, medium characteristics are critical—medium type, viscosity, etc., influence pump material selection and design. Consideration must also be given to the continuity or intermittent nature of the operation, which affects design aspects like motor power matching.
2. Performance Parameters
Performance parameters serve as the quantitative basis for selection. The API 674 standard specifies clear requirements and test protocols for pressure test pump performance. The rated discharge pressure must be greater than or equal to the maximum test pressure of the system with a safety margin. The rated flow rate must meet the pressure ramp-up speed requirements. The rated power of the drive motor must be determined based on pressure and flow rate, combined with the pump's overall efficiency, to ensure the motor does not overload.
3. Reliability
Core assurance lies in long-term stable operation reliability. Pump structural design must possess sufficient strength and rigidity to withstand high-pressure alternating loads and reduce fatigue damage risks. Seal performance is critical, with lubrication and cooling systems designed to ensure no significant leakage. Wear parts should feature excellent interchangeability and extended replacement cycles to facilitate maintenance and minimize downtime.
4. Safety Protection
Safety protection is paramount, with strict requirements outlined in the API 674 standard. Pumps must be equipped with reliable overpressure protection devices. Robust protective covers or shields must be installed at high pressure outlets to prevent media ejection injuries. Motors and control components must comply with electrical safety standards, with additional protection required for special environments. Furthermore, considering media characteristics, corrosion-resistant materials should be selected for pump casings and contact components.
Test pumps serve as vital inspection equipment in industrial applications, falling under the category of high pressure pumps. Elephant Machinery has consistently dedicated itself to advancing reciprocating pump technology across diverse sectors. Our test pumps strictly adhere to all provisions of the API 674 standard and have garnered widespread acclaim.
