Hot-dip galvanized seamless pipe
Hot-dip galvanized seamless pipe is the common name of hot-dip galvanized steel pipe. It is based on high-quality hot-rolled coils and uses a hot-dip method to attach a metallic zinc layer to the surface of the steel component. Since the surface of the steel is covered with a pure zinc layer, hot-dip galvanizing is also called "white plating". Hot-dip galvanized seamless pipes are used in most gas systems, and their specifications and quality requirements are very strict.
Advantages of hot-dip galvanized seamless pipe
1. Under great pressure
This type of seamless pipes can withstand very high pressures, and there are different models and parameters. We only need to choose according to our own needs, and we can choose seamless pipes that meet the requirements. They can also be used in high-pressure environments. .
2.Long service life
The service life of hot-dip galvanized seamless pipes is generally more than 50 years. Because it itself has a certain coating, its corrosion resistance is very good. Even if it is used in some harsh environments, it can still ensure good application results. Now according to regulations, when designing natural pipelines, it is necessary to ensure that the service life of the selected natural gas pipes must be more than 30 years. Compared with pipes made of other materials, the service life of hot-dip galvanized seamless pipes is indeed very good, and they can also meet the corresponding standard requirements.
3. Maintenance-free
Seamless pipes basically do not require maintenance because they have good weather resistance and have a long service life, so there is no need to spend other maintenance costs in the middle. Therefore, not only is the quotation preferential, but the later use and maintenance costs can also be reduced a lot.
4. Comprehensive protection
Hot-dip galvanized seamless pipe can ensure comprehensive protection because it can completely enter the workpiece into the galvanizing solution, so every position of the workpiece can ensure good galvanizing uniformity. In this way, there are no dead ends, and the thickness of the galvanized layer can naturally be guaranteed.
Things to note when installing gas hot-dip galvanized seamless pipes
1. Gas introduction pipe installation
Gas introduction pipes are prohibited from being laid in bedrooms, bathrooms, or areas with flammable and explosive materials, rooms with corrosive media, power distribution rooms, transformer rooms, flues, air inlets and other areas.
2.Installation of internal gas pipe
If indoor gas pipelines need to pass through areas such as floors, platforms, walls, and partitions, they should be installed in casings. The gas pipelines inside the building should be installed openly. If there are special requirements for construction and technology, they can be installed hiddenly, but they must be easy to install and repair.
3. Installation of gas on the ground floor
When the diameter of the above-ground low-pressure gas introduction pipe is ≤75mm, a tee with a wire plug should be installed outdoors at this time, and no additional valve should be installed.
4. Installation of gas introduction valve
The gas introduction pipe valve should be designed indoors as much as possible. If it is more important, a separate valve should be installed. Pay attention to the valve and choose a quick shut-off valve.
5. External factors of gas pipelines
Gas pipelines need to pay attention to the extreme deformation under the working environment temperature. If natural compensation cannot meet the requirements, a compensator must be installed, but be careful not to use a packing type compensator.
