Product Introduction

Clean Pipe Outer Surfaces Fast

Our external pipe shot blasting machine is made for continuous automatic cleaning of outer surfaces. It works on steel pipes, round bars, shaped steel, and steel structures. The model is QGW series. Multiple shot blasters are placed at angles around the pipe. The workpiece moves forward while it spins. Shots cover the whole outer wall. The rust removal grade reaches Sa2.5 to Sa3. This is perfect for pretreatment before coating, galvanizing, or painting. Jiangsu Haike Environmental Tech Co., LTD has 28 workers and a 30-acre factory. We are a high-tech company with many patents since 2014.

High Output with Low Labor

Our external pipe shot blasting machine runs continuously. It can handle tens of tons of steel per hour. Only one person works in the control room. The machine uses V-rollers or driven rollers for conveying. The workpiece rotates and moves forward. Multiple shot blasters throw shots at the same time. Shots are recycled. Dust is collected centrally. This machine works for seamless pipes, welded pipes, round bars, angle steel, H-beams, wind tower cylinders, and pressure vessel outer walls. The core benefits are continuous high efficiency, thorough rust removal, surface strengthening, and high automation.

Case from Liaoning Steel Structure Plant

A steel structure plant in Liaoning made H-beams that needed painting. But the steel surface had oxide scale. Paint adhesion was poor. We installed a HKQGW320 external pipe shot blasting machine. After treatment, the steel surface was clean with uniform roughness. Paint adhesion improved greatly. The customer said their product warranty period doubled.
