SMC Utility Box For Gas Meter

SMC utility box for gas meter is a sheet-like mold material mixed with more than a dozen composite materials such as unsaturated polyester resin, glass fiber, low shrinkage, calcium powder, and various additives, and formed by forging press at high temperature and high pressure. It has excellent advantages such as corrosion resistance, insulation, flame retardant, light weight, beautiful appearance, inability to recycle, and long service life (outdoor design service life can reach more than 40 years, indoor design service life can reach more than 60 years.

Key Features

1. environmentally friendly green

SMC composite material is a kind of halogen-free and harmful substances to human body. It is a new type of environmentally friendly material that meets the needs of future green development.

2. Chemical corrosion resistance

SMC composites have good corrosion characteristics such as acid resistance, dilute alkali, salt, organic solvents, and seawater, while metal materials are not acid resistance and are easy to corrode.

3. Lightweight and high-strength

Specific strength and specific modulus are one of the indicators to measure the load-bearing capacity of a material. The specific modulus of SMC composites is equivalent to that of steel, but its specific strength can reach 4 times that of steel.

4. Good fire and flame retardant performance

SMC composite material is fire-retardant and flame-retardant; it has been tested by national authorities to be a Class B non-combustible material

5. Good heat resistance

SMC composites have the ability to maintain their physical characteristics in harsh high temperature environments. Their operating temperatures range from minus 60 degrees to 150 degrees, and their thermal deformation temperatures are above 280 degrees.

6. Low thermal conductivity and small expansion coefficient

When there is a temperature difference, the thermal stress generated is much smaller than that of metal, and the thermal insulation performance is good.

7. Excellent anti-aging properties

SMC composites have anti-aging properties. Anti-aging performance testing shows that its surface aging thickness is less than 50 μ m for 20 years.

8. Long service life

The service history of SMC composites can prove that their service life is at least more than 30 years.

9. High production efficiency

The forming cycle is short and easy to realize mechanization and automation.

Why Choose SMC Over Traditional Materials?

SMC polymer composites have a compact structure and can easily cope with high temperature and humidity environments. They have excellent properties such as corrosion resistance, antibacterial, non-pollution absorption, and service life. Therefore, they are widely used in re-electronic power, aerospace, sports equipment, building reinforcement, etc. fields.

Product performance

1. The glass fiber content in the meter box material shall not be less than 23%;

2. The flame retardant rating of the meter box is V-0;

3. The raw materials of the product must be added with an anti-ultraviolet formula, so that the color will not change when placed;

4. Tensile strength ≥50MPA; Simply supported beam impact strength ≥35KJ/M; elongation at break ≥1.00%; bending strength ≥100MPA; Barfield hardness ≥50HBA; dry heat test 100℃±2℃/5H has no change; water absorption ≤0.5%; shrinkage ≤0.2%; oxygen index ≥20%;

5. Compression resistance: 50KG heavy object (contact area 10× 10CM), place it in any position (except glass windows) for 3 minutes (standard models 1, 2, and 3), the box will be free from damage;

6. Impact resistance: Use a steel ball with a weight of 0.5KG and fall freely from a height of not less than 1000 mm. After the meter box is impacted, the surface of the meter box should have no obvious damage, penetration damage, etc.(except for the window), The meter box structure has no deformation, and the connectors have no obvious loosening, etc.;
