2/5/· The HDPE liner pipe is manufactured to ASTM and ISO industry standards for PE4710 and PE100. To obtain a tight fit, SURE-Liner pipe is sized larger in diameter than the inside diameter of the HDPE pipeline, and is radially compressed rolled down during the insertion process.
After the liner is installed, HDPE sealing stubs are butt-welded to the ends of the liner and then covered with blowing flanges. Compressed air is then inserted into the HDPE liner and with the elastic nature of the HDPE material causes the liner to expand tight against the HDPE pipe internal wall.
Since Year 1995, Green Cosmos has been installing such HDPE leak detection liner system for numerous Owners, Clients and plant operators in the oil & gas industry. Total quantum of HDPE leak detection geomerane liners, of varying thickness 1.5mm ~ 2.0mm, supplied and installed by our HDPE pipe for sale to date is in excess of 500,000m 2 for petroleum pipes foundation pads with diameter PE100
The HDPE Pipe Model, developed by the PE100+ Association with inputs from many industry experts, includes the most frequently asked questions and answers Q&A''s of all the elements through the pipe system value chain: design, materials, construction
Install the hdpe pipe according to approved shop drawing. The installed hdpe pipe shall be inspected by the consultant. After approval for installation conduct the hydro pressure testing of the hdpe piping system. hdpe pipe welding risk assessment, ITP and.
HDPE is a good insulator, therefore at this sPE100 ISO9001e it is necessary that the correct heating depth of the pipe ends is obtained. Only a small amount of pressure 0,01 N/mm² is required to maintain the contact of the ends with the heating element. The heat will
Fusion welding method of installation HDPE liner: Overlap the panels of geomerane approximately 100mm- 150mm prior to welding. Clean the seam area with a dry cloth to remove dust, dirt prior to seaming to assure that the area is clean and free of moisture, dust dirt or debris of any kind.
A folded HDPE liner can therefore be installed at aient temperatures without the addition of heat. Once installed in the host pipe the HDPE material is then heated to near melt temperature 250ºF+- to form the plastic material into the inside shape of the
send the pig, plate and cable or rope from one end of the host pipe to the other. The metal plate acts as a Go/No-Go gauge such that if the pig and plate can get through the section of host pipe, the HDPE liner can be installed without obstruction.
The merane liner shall terminate within an anchor trench loed .5 metre away from the top of the eankment. Once the merane is in place the anchor trench must be backfilled and suitably compacted to prevent slippage of the merane.
HDPE is an excellent product for large appliions that require UV and Ozone resistance, chemical resistance or high-quality installations. Typically used in landfill and mining appliions, this product is delivered in large rolls with a width of 22.5'' and is heat welded in the field by trained technicians providing a high quality, test certified installation.

Both pipe clamps must be adjusted so that they hold the pipe tightly enough to withstand the force of the welding process. Press the pipe ends against hot plate by briefly applying a high pressure. Continue heating very low pressure until an up stand of 1 mm has formed.
Our Concrete Jacking pipes HDPE lined range from DN300 – DN900 is named as PERFECT PIPES. The PERFECT PIPE consists of a 360° synthetic liner made from high-density polyethylene HDPE, which is firmly anchored into a concrete shell. The HDPE liner stands out for its ongoing resistance to all standard chemical loads, high pressure flushing Puhui Pipe manufacturer in China

Installation Manual. The four ISO systems Standards, ISO 11296-11299 cover plastic pipes in renovation of gravity sewerage, pressure sewerage, water and gas supply respectively. Each requires that an installation manual be provided by the installer of the plastic pipe. Clause 9.4.1 Installation: requires that the installer provide an installation Puhui Pipe manufacturer in China
The primary in-service loads for the replacement HDPE pipe will depend on the appliion- i.e., non-pressure e.g., gravity sewer or pressure e.g., gas or water. For non-pressure appliions, the pipe stiffness or wall thickness must be sufficient to withstand the external hydrostatic pressure due to the anticipated height of the water table above the pipe.

A thick, durable, HDPE liner can be placed in exposed appliions where the cost of other materials may be prohibitive. HDPE has excellent chemical resistance, which is often the driving force behind its selection. HDPE is a field asseled lining material that cannot be practically fabried in the shop.
HDPE liner provides the new or old HDPE pipe with greater strength and protection from erosion and corrosion by closing off the HDPE pipe inside walls from the flow. The interior walls of the HDPE liner are also very smooth, resulting in superior fluid flow due to a reduction in resistance and friction.
HDPE High Density Polyethylene is the most widely used geosynthetic liner today. It enjoys particularly high acceptance in the waste and mining industries. A cost effective and environmentally beneficial solution for protecting pipelines from internal corrosion and abrasion using high density polyethylene pipe. liions include potable Puhui Pipe manufacturer in China

The product’s physical properties make it applicable to open-trench, horizontal directional drilling, pipe-bursting and slip-lining installations. It can be manufactured with the color striping to identify appliion, such as a blue stripe for potable water, a green stripe for PE100
In our technical world the lifetimes of HDPE geomeranes in landfill lining systems have been variously estimated to be between 200 and 750 years. At the other end of the scale installed HDPE lining systems in other appliions, typically exposed pond liners
