Various types of pipe couplings on the market
Types of polyethylene plumbing
Hot and cold water piping of buildings
This type of plumbing is almost the easiest type of plumbing. In the past, this type of piping used galvanized pipes. Two hot and cold pipelines run parallel to this pipeline, which is why it is called hot and cold piping. Cold and hot piping is now used with polypropylene pipes. Plumbing with this type of pipe has made it easy for many anchors. Alongside this pipe are pipes with couplings called so-called five-layer pipes, which are not implemented in many buildings because of their high cost, but their use is expanding. There are all kinds of water pipes in the world. Like copper plumbing. But in Iran, the most common type of piping is polymer tubes.
Different pipes are used to transport sanitary and gray building wastewater. In the past, cast iron was used for this type of piping. Cast iron was one of the raw materials for sewage piping due to its resistance to other materials at that time. After the high quality standard Polyka pipe was marketed, cast iron pipes were replaced by polymer pipes. These pipes had simple operation and good resistance to sewage. But on the other hand, these pipes have lost heat and become problematic in fires. This problem was remedied by changing the construction of buildings and standards to cover sewage pipes. Nowadays polyethylene pipes and pipes fit a large part of consumable pipes which are selected according to the design engineer’s opinion as well as economical estimations.
Household and commercial gas piping
Domestic and commercial gas pipelines are operated by executives who have the necessary permits to execute them from the building engineering system. This plumbing should be carried out by experienced people and professional pipe welders. The safety issue of this type of plumbing has made it the most sensitive type of plumbing in the building. Domestic and commercial gas piping should be done using manmade (seamless) pipes or heavy duty seam pipes. After plumbing, its implementation is verified by the engineering system supervisor. Domestic gas piping refers to the pressure of 1.5 pounds per square inch and commercial piping to 1.5 pounds per square inch.
Boiler and engine room
An engine house is the heartbeat of a building and it provides the energy needed to create a comfortable environment for residents. The machine shop consists of equipment that requires plumbing to transfer water between them and complete the process. Black pipes are always used for plumbing and circulating water. Black pipes must be connected by a pipe welder and piping must be performed by experienced persons. The piping of the slaughterhouse should be fully accurate and traceable and marked to the part of the riser for each section. Executors of this type of plumbing must adhere to the taste and beauty of its operation in order to extend both the service life of the engine and to make its maintenance easier and less costly.
Industrial water plumbing
Industrial water piping is done using steel or polyethylene pipes. As the name implies, this type of plumbing is carried out in industrial centers other than residential, commercial and public buildings. The characteristic of this type of plumbing and its differentiation with other plumbing is first of all the water used which is water other than drinking water. This type of plumbing also has a larger diameter than domestic plumbing. This type of plumbing is used in factories, agricultural fields as well as water lines. Polyethylene pipes are commonly used to perform this type of piping in places where water is saline.
Industrial gas piping
Industrial gas piping involves piping pipelines that have a gas pressure of between 2 and 2 pounds per square inch. For this type of heavy-duty steel pipes or polyethylene pipes with welding electrofusion are used. Implementation of this type of pipeline requires the approval of the Ministry of Industry and Mining. Special gas welding is done in industrial gas steel piping, and must be handled by experienced and experienced professionals called code welders. Polyethylene gas piping is used to transport gas to buildings. Industrial piping is implemented in the construction of the gas substation, oil and gas and petrochemical industry pipes, special pipes that require high safety, and gas transmission pipes from the substation to the home.
PE plumbing Fitting in different sizes for export
Hdpe tube size and dimensions
PE100 can be manufactured in a wide range of pipe diameters from 16 mm to 2000 mm. Even larger diameters can be created by creating suitable extrusion molds. However, the common tube size range is from 32 mm to 1200 mm.
Dimensions – Size and dimensions of pipes and tubes
The nominal diameter of a PE100 pipe is its outer diameter, not its inner gap diameter. Polyethylene PE is a widely used material and is commonly used as water pipes in the properties of PE 50, PEH or PE-HD (high density polyethylene). PE pipes are manufactured at different pressure grades – PN grades – which represent the pressure in rods that support the pipe with water at 20 degrees Celsius.
Standard diameters in this range are:
- 32 mm 63 mm 90 mm 110 mm
- 125mm 160mm 180mm 225mm
- 250 mm 280 mm 315 mm 355 mm
- 400mm 450mm 500mm 560mm
- 630mm 710mm 800mm 900mm
- 1000 mm 1100 mm 1200 mm
The diameter of the inner drill for each of these sizes depends on the SDR of the pipe. Non-standard tube sizes can be produced for specific applications if necessary.

Wholesale distributors of PE plumbing fitting in Iran
Polyethylene production line is very complex and polyethylene production is a chemical process that is done in petrochemicals and in a complex process n iran. Production of polyethylene as the most consumed and simplest polymer in the world follows a certain complexity and innovation. Also known as Pipe Grade is Pipe Grade and polyethylene materials which are used for rotary molding and ……
The polyethylene produced is essentially colorless and white, used for coloring with HDPE-based additives called masterbatches, and in some grades such as rotary polyethylene materials, mineral pigments are used.
In general, polyethylene is a family of resins obtained by the polymerization of ethylene gas (C2H4). Catalyst and polymerization of this material can control various properties such as density, melt flow index (MFI), crystallinity, branching and lattice degree, molecular weight and molecular weight distribution. Low molecular weight polymers are used as lubricants.
Medium molecular weight polymers are paraffin blendable waxes, and ultimately, polymers with a higher molecular weight of 6,000 have the highest consumption in the plastics industry. Polyethylene contains a very simple structure, which is simpler than all commercial polymers.
How is the quality of Iranian plastic pipes and fittings?
1- Corrosion resistance of polyethylene pipe to polyethylene galvanic pipe
This feature is actually the most important reason for using these pipes in the sea because the combination of air and water, especially seawater, is very corrosive to conventional metal pipes. It is worth noting that galvanic corrosion of polyethylene pipes is almost zero.
2- Resistance to rot, abrasion and impact
This property, along with the preceding one, significantly increases the useful life of these pipes compared to pipes and others. One example is a project implemented in Oman in 1996 for the Shell Group. The project was replaced by a 19-km-long corrosion-damaged carbon-steel pipeline with PE 100 (Water / Crude) grade polyethylene pipes.
According to the environmental conditions, the working life of polyethylene pipes is at least 15 years. No defects and leaks have been reported in these pipes since 1996, while the useful life of the steel pipes under the same conditions has been for a maximum of 2 years. Polyethylene pipe at sea
3. Good flexibility
This feature makes it easy to install these pipes and requires less fitting. The bending radius of the polyethylene pipe is 20 times its average outer diameter.
4. Very high collapsibility along the pipe
This property is characterized by the shul of the different seasons and the longitudinal contraction and expansion of the pipe and is the most suitable shrinkage material against other types of pipes.
5. Light weight
These pipes are much less weighty than steel pipes, making them easier to transport and store and less expensive.
6. Excellent resistance to earthquakes and landslides
Due to high tensile strength in polyethylene materials and sufficient strength against impact pressure, polyethylene pipes show the best resistance to earthquake vibrations and displacement of soil layers. For example, the damage data on polyethylene pipe caused by the Kobe earthquake in Japan were zero.
PVC Pipe Transition Coupling for Plumbing
Materials known as hard PVC are one of the most widely used and durable materials in the field of construction and urban installations in the past few decades. By adding a softener and lubricant to the PVC, the soft tube is manufactured and supplied.
The characteristics of PVC pipes depend on the type of their raw materials. Resin called PVC, the main component of PVC pipes, is a polymer made from gas or oil in combination with saline water and air. PVC resin, after undergoing each stage of manufacture and passing each stage of manufacture, converts to PVC pipes with various heat stabilizers, oils and other chemicals mixed with devices known as extruders. Is coming.
The characteristics of PVC pipes are examined in several respects. These include the type of base resin used, the impact strength, the tensile strength of the various components, the modulus of elasticity in the tensile process, and the heat-induced deformation. In addition, the degree of strength against chemicals and acids is also an important indicator of the classification characteristics of PVC pipes.
In Iran, the PVC pipe classification and production specifications are published by the Iranian Institute of Standards and Industrial Research and comply with international standards as follows:
- The PVC pipe, or polycha, is generally divided into three categories
- Ordinary PVC pipe or low pressure
- Semi-strong PVC pipe
- High pressure PVC pipe
