Bist baspar Espadana’s Polymer Fittings
A number of polymer fittings include brass nuts. These nuts also play an important role in the quality of fittings having one metal end and one stem end.
Bist baspar Company has precisely designed these brass parts with a great deal of sensitivity. Not only have the unique design of this company and use of high quality ingots with desirable alloys, on the one hand, and performing the plating process with a resistant, shiny, and relatively rare metal; that is nickel (which makes the brass nuts more resistant to corrosion and abrasion, and which increases their hardness, as well as causing them to gain anti-friction properties), on the other hand, completely resolved all the problems in this type of fittings manufactured by other companies, but the fittings with one metal end manufactured by this company are also of a quality beyond any imagination.
How to Join Bist baspar Pipes and Fittings Together
Bist baspar pipes and fittings are joined together through fusion welding and in accordance with the DVS and DVN standards. All the items in the table must be observed during each stage of the welding process. After attaching an appropriate standard mold to its plate, connect the welding machine to an electrical outlet, and set its temperature to 260 ± 10 °C. After the machine has warmed up, which takes 20 to 30 minutes, the welding process can be started.
|The welding guide according to the standard|
The mold and place of welding must be completely clean. Because the burned particles on them, cause welding to be done incompletely. If the ambient temperature is less than 5 °C, the heating time must be increased by up to 50%. And the device temperature must never be set to a temperature higher than the said temperature. Because if the device temperature is higher or lower than 260 ± 10 °C, molecular degradation or non-fusion occurs, respectively.
The Installation Stages
- Cut the pipes being used quite perpendicularly to their longitudinal axis, and remove any projections from the section which has been cut. Bear in mind that failure to cut them perpendicularly, causes changes in the depth of welding.
- Mark the welding depth on the pipe using a ruler or a steel measuring tape according to the welding guide table.
- Make the pipe and fitting reach the end of the welding machine’s mold, at the same time and under identical pressures. Be careful not to press the pipe into the mold farther than the marked point. Because the inner diameter of the pipe will be decreased, thus blocking the pipe.
- After the heating time, which is stated in the related table, is over, remove the pipe and fitting from the mold without rotating them, and immediately insert one inside the other up to the given welding depth, without twisting or rotating them.
Combination of metal and polymer is the latest technological solution to the production of durable and high-quality pipes.
Bist baspar five-layer pipes are a combination of metal and polymer, which have all the benefits of metal and polymer pipes, and which can be used for all the installations inside a building. Their extremely long lifespan at a pressure of 10 bars and a temperature equal to 90 °C, guarantees an efficient piping system without the need for maintenance.
Bist baspar Espadana’s 5-Layer Pipes and Their Technical Specifications
The 5-layer pipe consists of two polymer layers, two adhesive layers, and an aluminum layer, in a way that the inner and outer layers are polymer layers that are combined with the intermediate layer which is made of aluminum.
- Polymer layers: The polymer used in Bist baspar five-layer pipes is a special type of polymer, which is bought from the most prestigious petrochemical companies in the world, and which has a very high capability of maintaining the the hygiene of drinking water.
- Adhesive layers: The adhesive used in the pipes is also the best adhesive available in the industry, which plays a fundamental role in creating integrity and increasing the strength of the pipes.
The important point about the polymer and adhesive used in the pipes manufactured by Bist baspar is that these raw materials are made in South Korea, and are among the best raw materials in the industry.
- Aluminum layer: The aluminum sheets, which is used in the manufacture of the pipes, not only have the maximum thickness contained in the standard table, but are also washed with certain substances to remove any fat from its surface. This washing causes the welds to be more durable, thus producing pipes of much higher quality than those of other companies.

Bist baspar Espadana’s 5-Layer Fittings
In the course of our growing trend, we have taken steps to manufacture different types of 5-layer fittings, for which we used brass ingots with a copper content of 58%, which are highly formable and suitable for production.
This along with use of completely upgraded turning machines has allowed us to produce fittings with beautiful designs and of excellent quality, and supply them into the market.
These fittings are manufactured in two types, and supplied into the market:
- Press fittings:
In this model, the steel ring on the fitting is pressed around the pipe using a press jaw system of the same size.
- Coupling fittings:
In this model, just by fastening the nut available on the fitting, the brass ring inside it is firmly fixed around the pipe.
Among the creative features that this company’s 5-layer fittings have is the use of plastic rings in different colors. In a way that each size of the fittings has a plastic ring with a specific color for different types of fittings of the same size.
The advantages of using specific colors for different sizes of Bist baspar Espadana’s 5-layer fittings
- The apparent beauty of fittings
- You can quickly identify the size of reducers
- Increases the speed of installation
- Reduces the error rate in installation
- Reduces the failure rate of fittings due to incorrect installation
All press fittings of Size 16 have red rings.
All press fittings of Size 20 have orange rings.
All press fittings of Size 25 have green rings.
All press fittings of Size 32 have brown rings.
How to Join Bist baspar’s 5-Layer Pipes and Fittings Together
Due to different methods of joining in press and coupling fittings, each of the fittings has a specific method for installation, whose initial stages are identical in both types of fittings.
First, cut the pipe to the size you need, using a pair of metal cutting scissors or a pipe cutter. Next, widen the inside of the pipe using a calibration tool. Then using the blades at the end of the calibration tool and through rotary motions, shape the inner wall of the pipe into a conical form. It is very important to do this. Because the pipe wall has a cutting surface before calibration, and may tear the rubber O-ring of the fitting at the time of installation, which can cause improper sealing and water leakage.
- Press fittings:
After completing all the steps above, insert the pipe into the press fitting. To ensure that the pipe is fully inserted into the steel ring, you can use the hole which is at the end of the steel ring. Then, press the steel ring on the pipe, using an electric (or hydraulic) press which has a jaw system of the same size as the pipe and fitting.
- Coupling fittings:
In the coupling model too, after completing all the initial steps, first, move the connecting nut and put it around the pipe. Next, put the special ring around the end of the pipe. Then, insert the pipe into the fitting, and tighten the nut using a flat and/or adjustable wrench.
Note: Before starting the pressing operation in coupling fittings, remove the steel ring to ensure the presence of the rubber O-ring on the fittings. The absence of the rubber O-ring causes problems in sealing the areas having undergone the pressing operation.
The Applications of Bist baspar Espadana’s 5-Layer Pipes
Warming buildings in cold seasons had been a matter of concern for many years. Different companies around the world have been trying to provide new and different methods to warm buildings.
The underfloor heating system is one of the most up-to-date and modern styles to warm buildings. As you know, in methods commonly used in buildings, most of the heat generated is retained near the ceiling of the building, and there is no sign of that amount of heat near the floor of the building. Whereas, in the above-mentioned method, the heat is mainly generated at the floor of the building, which is desirable and pleasant. In this method, hot water enters 5-layer pipes through a collector. And given that these pipes are expanded in the floor of the building in the form of a regular network, the heat contained in these pipes is transferred to the surface of the floor.
Use of Bist baspar 5-layer pipe and fittings to create an underfloor heating system, brings you peace of mind and comfort in cold seasons.
|The fan coil heating system||The radiator heating system||The underfloor heating system||The ideal heating system|
|16 °C 20 °C 24 °C||16 °C 20 °C 24 °C||16 °C 20 °C 24 °C||16 °C 20 °C 24 °C|
The warm feet and cool head help your health. The underfloor heating profile is very close to the ideal profile.
The Advantages of Using Bist baspar Espadana’s 5-Layer Pipes
These pipes have the advantages of polymer pipes (referred to in the section of single-layer pipes). In addition, combination of metal and polymer has resulted in other advantages for the pipes, among which the following can be mentioned:
1- Due to their formability, these pipes are installed much faster and easier.
2- Due to their excellent capability of transferring heat from their walls, they are absolutely suitable for use in an underfloor heating system.
3- Due to their much lower longitudinal expansion coefficient than that of single-layer polymer pipes, the apparent problems, which occur in the implementation of single-layer pipes, and which can be seen from the outside of the work, would not be happen in these pipes.
- These pipes can tolerate high temperatures, even on a continuous basis.
