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 Sealing Iron (Q&A)

Q1: Why does the newly installed sealing iron still leak?
A1:
-Possible reasons:
1. There are impurities on the sealing surface during installation (such as iron filings and welding slag)
2. Uneven pre tightening force of bolts
3. Uneven flange surface (flatness exceeding the standard)
4. Selection error (pressure rating mismatch)
-Solution:
1. Thoroughly clean the sealing surface
2. Use a torque wrench to tighten in a cross pattern order
3. Check the flatness of the flange (should be ≤ 0.05mm)
4. Confirm the sealing iron material and pressure rating

Q2: Common manifestations of sealing iron failure under high temperature conditions
A2:
-Typical manifestations:
1. Metal creep deformation (deepening of indentation)
2. Oxidative corrosion (appearance of rust pits on the surface)
3. Stress relaxation (decrease in bolt preload)
4. Radial cracks appear on the sealing surface
-Preventive measures:
1. Choose heat-resistant alloy materials (such as Inconel 600)
2. Regularly check the fastening status
3. Set a reasonable replacement cycle

Q3: How to correctly measure the size of the sealing iron?
A3:
-Key measurement items:
1. Inner/outer diameter (using a digital caliper)
2. Thickness (measured at multiple points with a micrometer)
3. Flatness (check with a feeler gauge on the platform)
4. Tooth height of toothed pad (special depth gauge)
-Attention:
1. Clean the surface before measurement
2. Avoid edge chamfer positions
3. Record the maximum and minimum values

Q4: What is the standard tightening sequence for installing sealed iron?
A4:
-Standard process:
1. Manually pre tighten all bolts (confirm alignment)
2. Tighten in diagonal order three times:
-First time: 30% rated torque
-Second time: 60% rated torque
-Third time: 100% rated torque
3. Re tighten after hot operation

Q5: How to determine if the material of the sealing iron meets the requirements?
A5:
-Identification method:
1. Spectral analysis (most accurate)
2. Density testing (different materials have different densities)
3. Hardness testing (Brinell hardness tester)
4. Chemical reagent spot testing (requires professional personnel)
-Common material parameters:
|Material | Density (g/cm ³) | Hardness (HB)|
|---|---|----|
| Q235 | 7.85 | 120-150 |
| 304 | 8.0 | 150-200 |
| 316 | 8.0 | 160-220 |
