Product Overview

The HOLDWIN Pipe Inner Wall Sandblasting Gun is specially designed for cleaning and surface preparation inside pipes.

Featuring a 360° rotating blasting design, the nozzle distributes abrasive around the inner wall of the pipe for more uniform surface treatment. The front-mounted abrasive head rotates during operation, helping improve blasting coverage and efficiency.

It is suitable for pipe corrosion removal, rust removal, surface cleaning, and pre-treatment before coating or other protective processes.

Product Highlights

1. 360° Rotating Inner-Wall Blasting

The front abrasive head is designed to rotate during blasting, allowing abrasive media to be distributed around the pipe's inner wall.

The 360° blasting pattern helps provide more uniform coverage compared with conventional fixed-direction blasting.

2. Boron Carbide Wear-Resistant Nozzle

The internal nozzle is made of boron carbide, providing excellent wear resistance for abrasive blasting applications.

It is suitable for use with compatible abrasive media such as garnet and aluminum oxide.

3. Aluminum Alloy Protective Housing

The outer housing features an aluminum alloy jacket, providing a durable structure while protecting the internal blasting components.

4. Efficient Pipe Surface Cleaning

Designed specifically for internal pipe blasting, the rotating structure helps improve blasting coverage and reduce untreated areas inside the pipe.

Suitable for removing:

• Rust

• Corrosion

• Scale

• Surface Contamination

• Old Coatings

5. Wide Pipe Diameter Compatibility

Designed for pipes with an inner diameter of 50–150 mm, making it suitable for a variety of pipe cleaning and surface preparation applications.
