Product Certification
Product packaging 
1. Principles of Packaging Design
Protection Shock proof and buffering: precision accessories (such as instruments and valves) need to be filled with foam, bubble film, pearl cotton, etc. to avoid damage caused by transportation shock.
Moisture and rust prevention: Metal components (such as pipelines and flanges) need to be coated with rust prevention oil and packaged with moisture-proof film or vacuum. Desiccant should be added during sea transportation.
Anti pressure and anti drop: Heavy accessories (such as burners and drums) are reinforced with wooden boxes or steel frames, indicating the load-bearing direction and stacking layer limits.

2. Standardization and identification
Comply with international transportation standards (such as ISO, ISTA), indicate weight, size, lifting point, "fragile", "moisture-proof", "upward" and other markings.
Dangerous accessories (such as fuel injectors) must be labeled with UN certification and comply with the International Maritime Dangerous Goods Code (IMDG).

3. Container division strategy
Small items (bolts, washers) should be packaged in a uniform size box to avoid loose parts; Large items (heat exchangers) are individually customized in wooden boxes with supporting frames inside.

Product transportation
Transportation mode selection
1. Shipping by sea
Suitable for bulk accessories such as steel plates and large pipelines, pay attention to container size (20GP/40HQ) and load balance.Sea freight requires anti salt spray treatment, with moisture-proof agents placed inside the container and sealed.

2. Land transportation
Heavy accessories (over 3 tons) require flatbed trucks or low chassis vehicles, and routes should be planned in advance to avoid height/weight restrictions.Cross border transportation inspection of various countries' requirements for wooden packaging (such as ISPM15 fumigation certificate).

3. Air freight
Urgent small items (electronic controllers) should be prioritized for air transportation, and the weight of each item should be controlled (usually<100kg) to reduce packaging weight and save costs.

FAQ:
Frequently Asked Questions about Boiler Rollers (Q&A)

Q1: What could be the possible reason for the abnormal noise emitted by the roller during operation?
A1: 
Possible reasons:
Bearing damage or insufficient lubrication (dry friction sound).
Uneven wear on the surface of the roller (periodic abnormal noise).
Track deformation or installation deviation (metal scraping sound).
Solution:
Check the lubrication system and add high-temperature grease (such as Shell Gadus S2).
Stop the machine and measure the roundness of the roller (if the error is greater than 0.1mm, it needs to be replaced).
Adjust the track parallelism using a laser calibrator.

Q2: How to deal with peeling or cracking on the surface of the roller?
A2:  
Cause analysis:
Material fatigue (caused by long-term thermal stress).
Thermal shock (frequent boiler start-up and shutdown).
Hard objects get stuck (such as coal gangue or metal fragments).
Response measures:
Replace with high-strength material (such as 42CrMo quenched and tempered steel).
Install preheating program to avoid sudden temperature rise in cold state.
Check the fuel pretreatment system and remove large impurities.

Q3: How to prevent frequent damage to roller bearings?
A3: 
Common triggers:
Sealing failure (ash entering the bearing chamber).
Overloading operation (grate load>design value).
Lubricating grease undergoes high-temperature carbonization.
Improvement plan:
Replace with a labyrinth seal and nitrogen purging device.
Verify the load and increase the number of rollers (refer to Q=n × P/η).
Replace synthetic lubricating grease with a drip point ≥ 250 ºC (such as Mobil SHC 460).

Q4: What should be done if the roller deforms in a high temperature environment?
A4:  
Root cause of the problem:
Insufficient temperature resistance of the material (such as ordinary carbon steel used for working conditions above 400 ºC).
Cooling system malfunction (water-cooled roller water cut off).
Solution steps:
Priority should be given to using ZG40Cr25Ni20 heat-resistant steel rollers.
Check the pressure (≥ 0.3MPa) and flow rate (≥ 5L/min) of the cooling water pipeline.
Install infrared temperature monitoring (control surface temperature ≤ 450 ºC).

Q5: Is the contact surface between the roller and the track worn too quickly?
A5:  
Reason for accelerated wear:
The track hardness is insufficient (HB < 200).
Improper matching of roller rail hardness (recommended rail HB>roller HB+50).
Coal ash contains abrasive particles such as quartz.
Optimization plan:
Track surface welding wear-resistant layer (such as Duroxite 101).
Adopting ceramic composite rollers (coated with alumina).
Increase the frequency of ash cleaning (1-2 times per shift).
