Galvanized steel pipe insulation - an important procedure that increases the period of their operation. With proper installation line will always be protected from atmospheric influences, most importantly follow all the rules and adhere to the housing of laying the main recommendations.
Why and protect the pipeline from which
Pipes made of iron, metal alloys, plastic, metal-plastic. All of them have their own term of "life" and wear during operation under the influence of the environment in which there are (precipitation, sunlight, temperature, humidity, soil pressure or water). Furthermore, the wear pipe from inside is influenced transported substances. Therefore, in order to extend the period of their use, protection is a must.
Metal pipes are strong, reliable, but not protected from corrosion, corrosive pipe outwardly. If you do not make the insulation, in the near future their wall will lose its strength and will soon require replacement.
Corrosion is formed by:
- High humidity, rain, snow. With direct contact, iron rust, pipe wall thinning and collapse.
- Exposure to chemicals. Metal is also covered with rust, which leads to the destruction of the pipes - is typical for the chemical industry.
- Wandering stream. The electric current destroys the metal lines that are in the earth.
- A low temperature air. Frost lowers the temperature of the fluid passing or freezing (water, fuel oil, crude oil, diesel fuel, etc.) As a result, there is condensation on the surface of the pipes.
All of these types of destructive phenomena, destroying the transport pipeline pipe, cause damages in connection with the repair and the loss of the transported products.
The failure to protect the pipe from
Tube life varies depending on conditions of their operation, maintenance and service. Metal water pipe in the ground without insulation, comes into disrepair after 10 years of work, and probably earlier, taking into account the presence of harmful factors listed earlier.
Gas distribution pipeline, Oil wiring, heating, despite the fact that located above the ground, with the lack of insulation materials will be ruined after about a e same time. In places of connections, where the metal has undergone thermal load (welding) - will wear faster.
Important! With proper installation of galvanized pipe insulation, their operation period is increased to 40 years.
There are two options to solve the problem:
- Conduct a metal replacement for plastic.
- Use insulating materials to protect metal pipework.
Metal safer plastics and, if properly protected against corrosion, it will serve more than the stated terms. Due to strength - it is more expedient to use metal pipes. Protect them from external influences destroyers in various ways:
- coat paint or resin;
- use for waterproofing pipe winding;
- to surface a polyethylene;
- covered with polyurethane foam.
But the listed material is also in need of protection, as falls under the influence of the active medium. Therefore, the best solution to protect the tubulars will use galvanized isolation. Such coverage is practically not subject to corrosion processes. It can withstand temperatures from -3500C to 4200FROM. It all depends on the method of galvanizing steel.
Where applicable galvanized protective cover?
Galvanized casing is used for protection and insulation of chimneys, exhaust gas pipes in private homes. Also used for pipelines in the oil industry.
Casing the zinc is essential thing for coating the surface of a heating highways. It not only protects the metal from destruction, but also reduces the heat loss.
The advantages possessed galvanized isolation:
- attractive appearance;
- easy installation;
- durability.
In the chemical industry, zinc casing is used to protect workers from inadvertent contact with hot surfaces, the work that can cause injury to man.
Fitting Technology galvanized casing
When the assembly work, the connection between the housings is made through existing locking recesses. Additionally, docking places, used collars and dressings. Pipe line not always have an ideal straight line and form a tiered different geometric shapes: angular transitions arch protrusions.
Important! The insulation should fit tightly against the pipe surface. In cases of space availability, moisture may penetrate and continue to destroy the material.
For the isolation of these forms using sophisticated types of covers:
- Cylinder, with unprofitable latches;
- fitting (tee), - to protect the pipeline at points of divergence;
- a spherical cone;
- removable box - for the protection of working motors and valves.
Mounting housing galvanized done manually - team of workers, in view of previously established insulation. It can be any kind of mineral insulation: mineral wool, basalt slab, extruded polyethylene, etc. After stacking the material must be secured via wire frame. To do this, set the rods, which do not allow the slide connecting rings and bands.
Due to its collapsible design, installation of casings does not require special skills of employees. Galvanizing, plastic, easily cut, drilled and complicated in operations related to the fitting parts. It requires a minimum of tools and skills.
Protect the engineering design of galvanized insulated. This will not only extend the life of your systems: water, gas, oil transport, heating oil and other refined petroleum products, save heat and destroy your designs beautiful.
