HDPE - products : the advantages and disadvantages

Features HDPE

All IPA products possess similar properties, regardless of their destination.These characteristics are as follows:

1. Long life - manufacturers guarantee 50 years of use.
2. High resistance to aggressive media - plastic products do not corrode and are biologically inert.
3. quality Elastic - plasticity of the material avoids the communication gap when water freezes and large deformation at the ground shift.

As we can see, the distinctive quality of the IPA are its advantages.And if these features add ease of installation, light weight, and democratic price, it becomes clear why the products of HDPE became popular.

Compared with the listed advantages of HDPE disadvantages seem to be insignificant.So, to reduce the time of communication service can ultraviolet rays and temperature rise form fed liquid can cause deformation and even melting material.Oxygen permeability is also considered a disadvantage.

manufacturing methods

HDPE HDPE pipes are manufactured with the help of one of the three technologies.

1. Pneumatic formation - the polymer is fed into a mold, where the product is formed under the influence of air blower pressure.
2. Extrusion - polymer melt, after which the mass is extruded from the extruder, and solidified is drawn in the form of the finished product.
3. Injection molding - mass of the polymer is injected into the mold and spread evenly over its walls under high pressure.

Where used HDPE pipe

Appointment of polyethylene pipes is determined by three parameters: an indicator of the strength of polyethylene and an outer diameter of the brand.

mainly HDPE products are used in pressure and gravity pipelines and communication cable.

Smooth pipe discharge type is used for water and heat supply.It has a high internal resistance and low gas diffusion ability, ensures smooth movement of the transported liquid.

Dimensions produced communications range from 16 to 110 mm and length up to 12 meters or more.Such articles may have one or two layers.

HDPE pipes for non-pressure systems have good heat resistance and stiffness, for drainage and sewerage work in high-pressure conditions outside.

diameter non-pressure pipe systems household is 110 mm, the industry - more than 300 mm.The most common sewer systems use dual-layer pipes HDPE-LDPE type.

box for cable should have smooth inner walls, and increased stiffness.This product should protect the internal electrical wiring from mechanical damage and moisture.

box for wiring can be both single-layer and double-layer.Single wall pipe is used in places where communications are relatively easy to build.In areas with high load-applied double-walled HDPE HDPE pipes.

Installation IPA communications

Regardless of differences in purpose, any pipe can be built into the pipeline system the following main ways:

1. threaded method - mounting fittings and couplings, carried out using a simple set of spanner.Thus the channels are connected to the cable.
2. way to weld - welding the joint between the pipes, expensive tools required for its implementation.
3. Compression method - installation on the push-in connection or a press-fitting is carried out using a set of key-press.So connect the small diameter pipe.

After reviewing the information, what is the HDPE product, what they do and what their differences, it is easy to select materials appropriate settings for you.
