Product Description

Product Introduction
         Grate Pin/Stoker Pin is a key connecting component in boiler combustion systems such as chain grate,Scale grate and reciprocating grate, mainly used for:
Fix the grate plates to ensure their neat arrangement and stable operation.
Transmitting power to evenly distribute the tension of the grate drive device across the entire grate surface.High temperature and wear-resistant, capable of withstanding the high temperature of the combustion layer (usually ≤ 1000 ºC) and coal slag friction.

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 Stove Sales (Q&A)

Q1: What is the main function of grate sales?
A1:
-Fix the grate plates and keep the grate neatly arranged
-Transmitting driving force to ensure smooth operation of the grate
-Endure high temperature combustion and coal slag friction

Q2: What are the common reasons for grate pin breakage?
A2:
1. Material fatigue (long-term high-temperature operation)
2. Uneven stress caused by installation deviation
3. Unqualified material or improper heat treatment
4. Overloaded operation

Q3: How to determine if the grate pin needs to be replaced?
A3:
-Diameter wear exceeds 10% of the original size
-Obvious cracks or deformations appear on the surface
-The bending degree of the sales body exceeds 2mm
-Fixed parts (such as threads, slots) are damaged

Q4: How to deal with the stuck grate sales?
A4:
1. Stop and cool down before attempting to rotate
2. Use specialized loosening agent for penetration
3. Gently tap and vibrate (to avoid damaging the grate)
If it still cannot be removed, it may be necessary to cut and replace it

Q5: How to choose grate pin materials for different fuel boilers?
A5:
-Coal fired boiler: ZG40Cr25Ni20 and other high chromium nickel alloys
-Biomass boiler: 1Cr18Ni9Ti stainless steel (chlorine resistant)
-Garbage incinerator: ceramic composite coating pin
-Gas boiler: alloy steel such as 35CrMo is sufficient
