Product Overview
Lots of plant operators go for pipe conveyor belt (also called tubular conveyor belt), when dust control and zero spillage become big headaches on site. This belt folds into a closed tube during running. It locks bulk materials fully inside rubber tubing. No material spill off, little dust blow out, and keeps outside dirt away from conveyed goods.
It fits conveyor layouts with tight horizontal or vertical bends. Works great for jobs with strict local environmental rules. Many sites skip extra transfer points just by switching over to this tubular belt solution.
Features
- Two reinforcement options: high tensile steel cords or multi ply textile carcass. Both deliver reliable tension strength for long distance, heavy volume bulk handling.
- Full set of cover rubber grades available. Each holds up well under continuous flexing, impact and cyclic load in real world plant conditions.
- Built in cross section rigidity. The tubular shape stays stable even under full load; avoids collapse or unwanted deformation.
- Tuned longitudinal elasticity. Makes the belt perform reliably on routes with sharp curve sections. Less need to build extra transfer stations.
- Carcass stiffness varies across belt width. Edges are made more flexible. This ensures firm, consistent overlap once the belt forms a pipe. Hardly any gaps open during normal running.
- Cuts material loss caused by spillage. Helps sites meet emission requirements.
- Handles high capacity and long haul conveying set ups.
Rubber Cover Options
Select suitable rubber compound based on your material and working environment:
- Normal Abrasion resistant:Standard choice for most regular bulk solids. Handles friction and particle impact in daily operation.
- Heat resistant: For hot feed like clinker, high temp ore and calcined products. Tolerates sustained high temperature contact.
- Low Rolling resistant:Brings down running friction. Cuts power draw for long conveyor lines and lowers your ongoing energy expense.
- Oil resistant: Use with oily or greasy bulk materials. Stops rubber swelling, softening and early performance failure from oil exposure.
- Flame retardant: Designed for underground mines and high fire risk zones. Limits flame spread once ignited.
- Acid & Alkali resistant:Resists chemical erosion when handling corrosive bulk or working in acid alkali fume surroundings. Slows rubber ageing.
Applications
Pipe conveyor belts handle bulk material transport across multiple industries, especially sites with high environmental protection expectations:
- Mining: Coal, ore and mine waste transport. Perfect for lines running close to residential zones or public roads.
- Power plants:Raw coal and coal ash delivery. Closed tube structure keeps coal dust from spreading to surrounding areas.
- Metallurgy: Move sinter, pellets and other metallurgical raw materials. Well suited for lines with frequent direction changes.
- Building materials: Limestone, cement clinker, gypsum and construction aggregates.
- Grain industry: Transport wheat, corn and similar crops. Shields grain from moisture, insects and external contamination.

FAQ
Q1: What real world benefits does pipe conveyor belt have vs regular open flat conveyor belt?
A: It runs as a fully sealed tube. Bulk material stays wrapped inside. You get nearly zero spillage and much less dust. Another practical plus: it can go through sharp bends. Normal flat belts need extra transfer stations to change direction, which adds cost.
Q2: Can pipe conveyor belts take both horizontal and vertical curves?
A: Yes. Its carcass is built for flexible routing. It supports horizontal turning as well as height change. Still you must follow system design on minimum curve radius. Don’t exceed design limits.
Q3: Fabric pipe conveyor belt or steel cord type — how to pick?
A: Pick multi ply fabric version for short to medium conveying distance, moderate throughput and cost sensitive projects. Go with steel cord type when you need ultra long conveying distance, heavy payload and high tension working conditions.
Q4: How do I decide which rubber cover grade to order?
A: Base your choice on actual conveyed material. Normal abrasion resistant works for regular ore and stone. Use heat resistant for hot material feed. Oil resistant for oily goods. Acid & alkali resistant for corrosive bulk. Send over your material temperature, chemical traits and site conditions, we can give practical suggestions.
Q5: Common field issues to watch out for during operation?
A: Operators often run into poor edge overlap, tube shape distortion, abnormal edge wear and cover rubber damage. Check roller sets, loading status and belt overlap on a regular basis. These simple checks help extend belt service life. Actual service life also depends on material abrasiveness and daily running hours.
Q6: Can we splice pipe conveyor belt on site?
A: Yes. Hot vulcanisation and mechanical fastener splicing are both workable options. Hot vulcanised splice gives better overall integrity and longer service life for pipe conveyor use.

Sidewall Conveyor Belt Sagging Solutions: QBF rubber Free Zone Base Belt Design Extends Service Life by 30%
Sep 18, 2026
According to industry statistics, up to 80% of sidewall conveyor belt failures occur due to rigidity loss–induced sagging during operation. QBF rubberaddresses this root cause with an innovative “free zone ” base belt design, significantly extending the service life of sidewall conveyor belts.
What Is Belt Sagging and Why Does It Shorten Belt Life?
Under heavy load, especially on the return run, the base belt often sags due to insufficient transverse rigidity. This sagging triggers a chain of serious issues:
Stress concentration – Sagging causes abnormal flexing at the sidewall root as it passes over the drum, concentrating stress in a localized area.
Fatigue cracking – Repeated flexing leads to fatigue cracks at the sidewall root, which can develop into through-wall damage.
Baffle detachment – Vibration and deformation from sagging transfer to the baffle connection, accelerating adhesive aging and causing baffle loosening or separation.
Once sidewall tearing or baffle detachment occurs, the entire sidewall conveyor belt often fails prematurely. Therefore, solving the sagging problem is the key to extending belt service life.
Root Cause of Belt Sagging
The core cause of sagging lies in structural deficiencies of traditional base belt designs:
Insufficient transverse rigidity – Traditional base belts cannot maintain a flat profile under heavy loads or long-span conditions.
Unbuffered stress transfer – The sidewall-to-base belt connection lacks a flexible transition, so abnormal sagging stress directly impacts the sidewall root.
Accelerated fatigue accumulation – Repeated flexing at stress concentration points causes cracks to grow from micro to macro levels.
Understanding these causes makes it clear: simply increasing sidewall thickness or changing the rubber compound is a temporary fix. The solution must start with the base belt structure.
Solution: QBF rubber Free Zone Base Belt Design
QBF rubber introduces a “free zone ” base belt design to directly target the root cause of sagging.
How the free zone Works
Blocks stress transfer – The free zone acts as a stress buffer, absorbing and isolating abnormal sagging stress before it reaches the sidewall root.
Dissipates flexing energy – The flexible edge allows the base belt to adaptively deform as it passes over the drum, spreading concentrated flexing over a larger area.
Protects sidewall and baffles – By mitigating the extra load caused by sagging, the risk of fatigue tearing at the sidewall root is greatly reduced, and the baffle adhesive layer no longer suffers excessive vibration stress.
Key Advantages of the free zone Design
Advantage
Result
sidewall tear resistance
Eliminates stress concentration points; fatigue life extended by 2–3 times
Baffle detachment risk
Smoother operation; significantly slower adhesive aging
Overall belt service life
Comprehensive service life increased by 30% or more
QBF rubber’s Free Zone Base Belt design achieves a leap from “reacting to sagging consequences” to “eliminating the root cause of sagging.”
Summary: Eliminate Sagging at the Source for Longer Sidewall Belt Life
The sagging problem in heavy-duty sidewall conveyor belts originates in the base belt structure. QBF rubber’s free zone design solves this industry pain point by blocking stress transfer, dissipating flexing energy, and protecting both sidewall and baffles.
If you are experiencing frequent sagging, sidewall tearing, or baffle detachment with your sidewall conveyor belt, contact QBF rubber for professional technical support and customized solutions.

Mining Vertical Lifting System Solution: Tackling Continuous Conveying Challenges for Deep-Mine Operations
Sep 17, 2026
As mining operations go deeper, vertical lifting efficiency and safety have become major constraints on mine output. Designed for deep shafts, inclined shafts and complex terrain, our vertical lifting system works across 0 500 m vertical heights and supports steep angle, long distance material transport. Thanks to modular design, high throughput and full lifecycle services, it has gained wide attention in the mining material handling industry.
Three Core Solutions for Varied Lifting Applications
Our portfolio includes three main product lines to cover diverse vertical transport demands.
Steep Angle Sidewall Conveyor Solution
Engineered as an alternative to conventional mine cages, this solution handles vertical heights from 0 m to 500 m. In inclined shaft conditions, throughput can exceed 10 000 tons per hour. It overcomes the low efficiency, intermittent nature of cage hoisting and enables fast, continuous material transfer from underground to surface.
Pocket Type Vertical Lifting System
Optimized for high height, high volume tasks, this system is ideal for muck removal shaft main lines and blind shaft intermediate transfer. Proven in tunneling projects, it runs stably above 250 m lift height with capacities over 800 m³/h. It fills performance gaps under tight space conditions and can reach lifting heights over 500 m.
Long Distance Rope track Conveying System
Boasting single spans beyond 2 000 m, this system serves mountain and river valley sites. It reduces transfer points, cuts energy consumption and lowers overall maintenance costs for difficult terrain material haulage.
Full Chain “EPC+M+O” Service Model
Beyond equipment supply, Bairui provides a complete EPC+M+O service package:
E (Evaluation & Custom Design): Custom engineer conveyors and belts based on mine geology, production targets and existing site infrastructure.
P (Core Equipment Manufacturing): In house production of sidewall belts, lifting pockets and drive units for reliable quality and on time delivery.
