Rock wool tube

What details should be paid attention to when installing rock wool pipes?

Construction preparation stage

Material inspection:

Before installation, carefully check whether the specifications, models, thickness, density and other parameters of the Rock wool pipe insulationmeet the design requirements. Ensure that the quality of the Rock wool pipe insulationis qualified and check the quality inspection report of the product, especially the key indicators such as thermal insulation performance and fire resistance.

Check whether the Rock wool pipe insulationis damaged or damp. If the Rock wool pipe insulationis damp, its thermal insulation performance and mechanical strength will decrease, so the damp Rock wool pipe insulationshould not be used.

Tool preparation:

Prepare the tools required for installation, such as knives, tape measures, hacksaws, brushes, glue, insulation nails, etc. The knives should be sharp so that the rock wool pipes can be cut accurately; hacksaws are used to cut larger rock wool pipes or make fine cuts; brushes are used to clean the pipe surface and the Rock wool pipe insulationinterface; glue is used to paste the interface; insulation nails are used to fix the Rock wool pipe insulationto ensure that it is firmly installed.

Pipeline surface treatment:

Before installing the rock wool pipe, the pipe surface needs to be cleaned and pre-treated. Remove impurities such as oil, rust, and dust from the surface of the pipe, as these impurities will affect the fit between the Rock wool pipe insulationand the pipe and reduce the insulation effect.

For pipes with anti-corrosion requirements, ensure that the anti-corrosion layer is intact. If the surface of the pipe is uneven, you can use sandpaper and other tools to polish it to make the surface of the pipe as flat and smooth as possible so that the Rock wool pipe insulationcan fit tightly.

Installation process details

Cutting and splicing:

Rock wool pipes should be cut with special tools to ensure that the cutting surface is flat and vertical. The cutting size should be accurate to ensure that the Rock wool pipe insulationcan fit tightly to the pipe. For the parts that need to be spliced, the splicing seams should be as tight as possible. Too large gaps will affect the insulation effect.

When the pipe has elbows, tees and other pipe fittings, the Rock wool pipe insulationneeds to be appropriately bent or cut and spliced ​​to adapt to the shape of the pipe fittings. When bending the rock wool pipe, be careful to avoid excessive bending that may cause the Rock wool pipe insulationto break. For some complex pipe fittings, the Rock wool pipe insulationcan be cut into suitable small pieces and then spliced ​​with glue or sealing materials.

Fitting installation:

When putting the Rock wool pipe insulationon the pipe, make sure that the Rock wool pipe insulationfits tightly with the pipe surface without any gap. You can start from one end of the pipe and slowly put the Rock wool pipe insulationin, adjusting the position while putting it in. If the pipe is long, multiple people are required to cooperate in the installation.

For pipes with larger diameters, in order to ensure the stability of the rock wool pipe, you can use insulation nails to fix it. The spacing of the insulation nails should be reasonably set according to the diameter and thickness of the rock wool pipe. The general spacing is about 20-30cm, and it is necessary to ensure that the insulation nails are firmly fixed and will not loosen.

Interface sealing:

The interface of the Rock wool pipe insulation(including the axial interface and the circumferential interface) should be sealed to prevent air leakage and affect the insulation performance. Special insulation glue, sealing tape or sealing putty can be used for sealing. When applying glue or putty, apply it evenly to ensure that the interface is completely sealed.

For pipes with waterproof requirements, waterproof sealing materials such as waterproof tape or waterproof glue are also required at the interface to improve the waterproof performance of the rock wool pipe.

Safety and protection measures

Dust protection:

Rock wool pipes will generate dust during cutting and installation, which may cause harm to the human body. Construction workers should wear protective equipment such as dust masks, goggles and gloves.

At the construction site, try to keep good ventilation, and use ventilation equipment such as exhaust fans to reduce dust concentration.

Fire safety:

Although rock wool pipes are fireproof materials, there is still a risk of fire if there is open flame or high temperature operation around during installation. Fireworks should be strictly prohibited at the construction site, and open flame operations such as welding and gas cutting are prohibited near rock wool pipes. If open flame operations must be carried out, appropriate fire prevention measures should be taken, such as using fireproof baffles to separate the Rock wool pipe insulationfrom the fire source.

Inspection and acceptance after installation

Appearance inspection:

After installation, the appearance of the Rock wool pipe insulationshould be inspected. Check whether the Rock wool pipe insulationis installed firmly and whether it is loose or falling off. Check whether the seal at the interface is good and whether there are gaps or openings.

Check whether the surface of the Rock wool pipe insulationis flat and whether there is damage or depression. If any problems are found, they should be repaired or replaced in time.

Performance test:

Simple insulation performance test can be performed, such as using thermal imagers and other equipment to check whether the temperature distribution on the pipe surface is uniform, and to determine whether the insulation effect of the Rock wool pipe insulationmeets the design requirements.

For pipes with waterproof requirements, waterproof tests can also be performed, such as water spray tests, to check whether the waterproof performance of the Rock wool pipe insulationis qualified.
