KT-307 Heavy-Duty Tube Bundle Unclogging Machine: Product Introduction

KT-307 Heavy-Duty Tube Bundle Unclogging Machine: Product Introduction

A Tube Bundle Unclogging Solution for Heat Exchangers, Boiler Tube Bundles, and Air Preheaters

In industrial production, heat exchangers, boiler tube bundles, air preheaters, condensers, evaporators, and other equipment are prone to pipe blockages after long-term operation due to scale, material deposition, coking, crystallization, rust, ash, and other fouling. Minor blockages reduce heat exchange efficiency and increase energy consumption; severe blockages can completely jam tube bundles, disrupting the stable operation of the entire production system.

Anhui Kuaitong Pipeline Cleaning Technology Co., Ltd. specializes in the R&D and manufacturing of industrial pipeline cleaning and tube bundle unclogging equipment. Drawing on the characteristics of blockages encountered in various industrial settings, we have developed the KT-307 Heavy-Duty Tube Bundle Unclogging Machine. This equipment is suitable for a wide range of industrial tube-bundle devices and can be configured with flexible shafts and alloy steel drill bits of different specifications to match different tube diameters and blockage types, providing industrial enterprises with a more efficient and safer mechanical unclogging solution.

1. Which Equipment Is the KT-307 Suitable For?

The KT-307 is mainly used for the maintenance of various industrial tube-bundle and heat-exchange equipment, including:

Heat exchangers

Boiler tube bundles

Air preheaters

Condensers

Evaporators

Surface condensers (steam condensers)

Economizers

Shell-and-tube heat exchangers

Various industrial process pipelines

The equipment is suitable for routine maintenance, blockage unclogging, and periodic cleaning of industrial equipment, helping to restore flow capacity and improve heat exchange efficiency.

2. Which Types of Blockage Can the KT-307 Handle?

The nature of fouling varies greatly across different industries, so the equipment must have strong adaptability.

Scale Blockage – Minerals in circulating water deposit over time to form hard scale, which is a common blockage type in power plants, refrigeration systems, and circulating water systems.

Material Deposition – In chemical, food, and pharmaceutical processes, the conveyed media tend to adhere to tube walls, gradually forming a deposit layer that can completely block the tube in severe cases.

Coking and Carbonization – Under high-temperature conditions, materials continuously coke and carbonize, creating hard coke layers that are difficult to remove with ordinary flushing.

Crystallization – Some chemical media precipitate crystals during temperature changes, accumulating over time to form crystalline blockages.

Rust and Particulate Debris – Iron rust, welding slag, and other particulate impurities in circulating media also build up and affect normal operation.

In actual field work, many blockages are mixed, composed of multiple fouling types. The KT-307 uses high-strength alloy steel drill bits that can be configured for different blockage conditions. It has strong adaptability to complex conditions such as material deposition, coking, crystallization, and hard scale.

3. Working Principle of the KT-307

The KT-307 uses a mechanical rotary unclogging method. Its 5500W power drive unit drives a flexible transmission shaft at high speed, which rotates the front-end alloy steel drill bit to progressively break down the blockage inside the pipe.

The equipment can be operated with or without water supply. When water is supplied, it flushes out the crushed debris from the tube and simultaneously cools the drill bit and shaft.

The KT-307 supports both dry unclogging and water-assisted cleaning, allowing flexible choice based on site conditions to maximise applicability.

4. Why Choose the KT-307 Heavy-Duty Tube Bundle Unclogging Machine?

Anhui Kuaitong Pipeline Cleaning Technology Co., Ltd. has continuously optimised the product design based on the real needs of industrial field operations.

Compared with traditional mechanical unclogging equipment, the KT-307 focuses not only on power output but also on long-term stable operation, operational safety, and maintenance cost control.

To address common issues in industrial settings – such as shaft damage, equipment overload, complex operation, and control system stability – the KT-307 incorporates intelligent control and structural optimisation to improve overall performance, making it more suitable for long-term use in industrial enterprises.

5. Core Technical Features of the KT-307

Intelligent Torque Adjustment System
During operation, the equipment automatically adjusts output torque based on blockage resistance, ensuring smoother power delivery. It eliminates frequent manual adjustments for different blockage levels, reduces impact from overload, and improves operational continuity.

Adaptive Shaft Protection Technology
The KT-307 is equipped with a new adaptive shaft protection technology that dynamically adjusts power output according to the load. Compared with traditional equipment, it effectively reduces wear on the flexible shaft and related consumables, lowers maintenance costs, and extends service life.

0–4000 rpm Stepless Speed Control
The equipment supports stepless speed adjustment from 0 to 4000 rpm. For different tube diameters, blockage levels, and site conditions, the speed can be flexibly adjusted, making the equipment adaptable to a wider variety of industrial tube-bundle unclogging tasks.

Manual + Wireless Remote Dual-Mode Control
The KT-307 supports both on-site manual control and wireless remote control. Operators can choose the most convenient mode based on site layout and working environment, reducing unnecessary movement and improving work efficiency.

Split-Type Structural Design
The KT-307 features a separate power unit and control cabinet. This design not only facilitates transport and on-site installation but also reduces the transmission of vibration from the power unit to the control cabinet, protecting sensitive electronic components. Anhui Kuaitong has carefully considered the demands of continuous industrial operation – the split design minimises vibration transfer, enhances control system stability, and extends the service life of the control cabinet and its components.

Parameter Memory and Voice Guidance
The equipment provides voice-prompted operating instructions and one-key recall of construction parameters. For repeated jobs under similar conditions, operators can quickly load previous settings, improving efficiency and reducing human error.

High-Strength Alloy Steel Drill Bits
The KT-307 is supplied with multiple specifications of high-strength alloy steel drill bits. Depending on tube diameter and blockage type, the appropriate bit can be selected. For severe blockages, including completely jammed tubes, mechanical unclogging offers strong adaptability. With proper operation and correct bit selection, the drill bits achieve both effective unclogging and good tube-wall protection.
