The equipment adopts a vertical or horizontal structure design, flexibly configured according to the steel pipe specifications and processing requirements. The core system includes an outer shot blasting chamber, an inner shot blasting boom system, a shot circulation system, a dust removal system, and an automated control system. During operation, the steel pipe rotates uniformly on the drive roller conveyor. The outer wall is cleaned from all angles by multiple shot blasters, while the inner wall is continuously cleaned by a retractable boom device.
In practical applications, the QG series equipment demonstrates significant technical advantages. Its high-efficiency shot blasters utilize special alloy blades with a service life exceeding 800 hours. The simultaneous internal and external wall cleaning technology increases processing efficiency by approximately 40% compared to traditional processes, with the processing time for a single 12-meter-long steel pipe controlled to within three minutes. The treated steel pipe surface achieves a cleanliness level of Sa2.5, with a roughness maintained within the range of 30-70 micrometers.
This equipment is particularly suitable for the following applications:
Internal and external wall treatment of oil and gas pipelines
Insulated pipes for urban centralized heating systems
Industrial water supply and drainage pipes
Pipes for steel structure buildings
Pipes for bridges and building structures
The equipment adopts a modular design, allowing for flexible adjustment based on the diameter and length of the steel pipe. The standard model can handle steel pipes with diameters from 100 mm to 2 meters and lengths from 6 meters to 12 meters. Special specifications can be customized according to customer needs. The automated control system is equipped with a user-friendly interface, making operation simple and allowing storage of various steel pipe processing parameters.
In terms of environmental performance, the equipment is equipped with a high-efficiency dust removal system using a cartridge dust collector, achieving an emission concentration of less than 15 milligrams per cubic meter. The shot blasting system is equipped with a magnetic separator and vibrating screen, ensuring a shot purity of over 99%. Equipment operating noise is controlled below 80 decibels, and the working environment meets occupational health and safety standards.
The safety protection system includes multiple protection measures such as emergency stop devices, access interlocks, and overload protection. Equipment maintenance is convenient; major components are equipped with inspection doors, and key components adopt standardized designs for easy replacement. Routine maintenance only requires periodic checks of shot levels and cleaning of the dust removal system.
