Characteristics

Because of the reasonable design and the advanced production technology, the Metal reinforced polyethylene(PE)spirally corrugated pipe possesses many advantages, such as high ring stiffness, resistance to corrosion and abrasion, light weight, convenient construction and installation etc..

It is a new kind of pollution-free plastic pipe which recommended by the Ministry of Construction. The features follows:

1 For the high elastic modulus of corrugated steel strip, the pipe possesses high ring stiffness.

Metal reinforced polyethylene(PE)spirally corrugated pipe makes use of the special corrugated steel as supporting structure. Because of steel’s high elastic modulus and pipe cross-section’s high moment of inertia, there are 4 ring stiffness classes for the pipe: SN8, SN10, SN12.5, and SN16. Its high ring stiffness breaks the limit that the highest ring stiffness of plastic pipe can only reach the SN8. It makes plastic pipe can satisfy various engineering requirements.

2 The HDPE materials is very stable is chemical reaction, the pipe can resist corrosion and abrasion, and has a long service life.

The steel is completely covered by HDPE, so only the HDPE is exposed to the liquid and the soil. HDPE is a kind of crystal Non-polar material, it is very stable and has no electric-corrosion. Pipe resists corrosion and abrasion, has a long service life.

3 Smooth inter wall, the transportation capability of the pipe is high

The inner wall surface of Metal reinforced polyethylene(PE)spirally corrugated pipe is smoother than concrete pipe. So the transportation capability of the pipe is obviously higher than that of concrete pipe under the same condition.

4 Hollow structure, light weight, convenient construction and installation

With the corrugated steel strip as supporting structure, it needs fewer raw materials than other plastic pipes. Metal reinforced polyethylene(PE)spirally corrugated pipe is light. It can be connected by many kinds of method, for example, electric melting belt; the transport and installation are convenient and simple.

5  HDPE and adhesive resin are combined with the steel strip closely in molten state.

As bond between HDPE and steel, there is a layer of adhesive resin which the steel strip’s surface coats with. To control the optimum temperature, pressure and time can ensure that HDPE and steel compound closely. It prevents the steel strip being rusty.

6 Flexible pipe, joint steady, resist to unequal settlement

Metal reinforced polyethylene(PE)spirally corrugated pipe possesses the characteristic of both rigidity and flexibility, when under pressure, the pipe and backfill soil can resist to external load and reasonable uneven settlements of soil.

Combined with the advantages of the electric-melting belt welding method and the patented technology of welding, it can ensure the welding quality be safety.

Q:Steel wire reinforced composite pipe with PE pipe what is the difference
The steel wire frame plastic composite pipe adopts high quality material and advanced production technology, so as to make it have higher pressure resistance performance. At the same time, the composite pipe has good flexibility and is suitable for long-distance buried water supply and gas transmission pipeline system. The pipe fittings made of steel wire mesh polyethylene composite pipe are made of polyethylene electric melting pipe fittings. When the utility model is connected, the inner layer of the outer layer of the pipe and the pipe are melted by the heating body of the inner pipe, and the pipe material and the pipe fittings are reliably connected together.
Q:Does the specification require plastic steel composite pipes to be treated as antiseptic?
The middle layer is a steel pipe, so the pipe bearing performance is very good, is different from the aluminum bearing is not high, the largest diameter pipe can only 63mm, the largest diameter of steel pipe can be done 200mm, even more; the middle layer of the steel tube is sealed, so the steel plastic pipe also has the effect of oxygen barrier, can for direct drinking water projects, and the inner layer and the plastic material, has good corrosion resistance.
Q:Central heating, heating, PPR pipe, or outside there is aluminum pipe? What's the difference?
The difference between the two is mainly PPR tube in the installation and use must be hot melt, bend can not turn directly; and aluminum plastic pipe is a direct turn, no hot melt, you can turn the actual situation.
Q:What are the advantages of PSP steel plastic composite pipe?
The industrial field can be widely used in petroleum, chemical, pharmaceutical, food, mining and other fields
Q:What is the KPS composite pipe?
A composite tube is a combination of two or more transistors in accordance with a certain law, which is equivalent to a triode, and the compound tube is also called a Darlington tube.
Q:What kind of pipe material does the building PPR pipe belong to? Is it a plastic tube or a composite pipe?
PP-R tube is also called type three polypropylene pipe. It is made of random copolymerized polypropylene and is extruded into tube. The injection is made into pipe fittings. It is a new plastic pipe developed and applied in Europe in the early 90s.
Q:Construction technology of internal and external double hot melt joint of PSP steel plastic composite pipe
Mark the outer weld depth with the marking plate and marker pen at the end of the pipe according to the requirement of the technological parameter table.
Q:What connection mode is used for XPAP crosslinked aluminum plastic composite pipe?
From the connection way, aluminum plastic pipe is a physical connection, simple and convenient, and its safety and reliability is very high. For example: card sleeve type connection.
Q:How is the stainless steel composite pipe produced?
As a general practice for metallic materials, the stainless steel sheet is closed to the other metal material and is then divided into tubes.
Q:How welded wire skeleton plastic polyethylene composite pipe?
A. welding process three factors: voltage, current and time are the parameters to set welding, welding parameters are important factors to ensure the quality of electrofusion welding. From the point of view of welding, setting the correct welding parameters essentially provides the welding area with the right amount of heat (electric energy is converted into heat energy). B. parameter correction: welding parameters may change from time to time (season), because (different regions), due to environmental changes and meteorological conditions in different geological conditions to make the appropriate adjustments to the strict discipline: on-site welding welding process parameters is confirmed, not allowed to change, must strictly abide by. C. pipes and fittings pipe inspection: focus on examination of the pipe surface have deep scratches, pipe inside and outside surface are unrecoverable protrusions or pits, pipe port sealing ring if there is a crack or fall off; to focus on examination of pipe thermal resistance wire is energized, whether there is a deep scratch damage to hot wire etc.. D. fixed length Piping: according to the needs of the site, the pipe needed in the process of pipe connection can not be entirely the whole pipe, so it is necessary to cut the fixed length pipe on the spot. The electric cutting saw is generally used in the field, because it is limited by the operating space at the bottom of the ditch,
