BAOSU® Polyethylene (PE) pipes shall be manufactured from polyethylene containing only those antioxidants, UV stabilizers and pigments necessary for the manufacture of pipes. BAOSU® PE Pipe is intended to be used for water supply intended for human consumption, including the conveyance of raw water prior to treatment and that of water for general purposes. Our company manufactured water supply PE pipe materials are PE100 resins.
We have advanced Germany Battenfeld PE pipe extruders and fittings injected machines. We can manufacture a complete series pipe and fittings according to GB/T 13663-2000,GB/T 13663.2-2005,ISO 4427:2007 standards.
1 Excellent toughness
BAOSU® PE pipe is a high toughness pipe, and its elongation at break exceeds 500%. PE pipe suits non-uniformity soil settlement and malposition, resistant earthquake good. It is demonstrated PE pipe which is the best choice of resistant earthquake pipe in the world.
In addition, PE pipe may coil, special small diameter PE pipe, reduces many fittings. PE pipe may bend and reduce construction difficulty.
2 Safety and health
Polyethylene material consists of carbon molecule and hydrogen molecule, harmless, health and reliable.
3 Excellent resistant stress crack
BAOSU® PE pipe has low notch sensitivity, high resistant shear strength and excellent resistant scratch, resistant RCP and SCG. It is proved PE100 excellent resistant scratch ability.
4 Low temperature resistant impact good
BAOSU® PE pipe is brittle in very low temperature, can operate safety in -60℃.
5 Excellent abrasion resistant
BAOSU® PE pipe and steel pipe abrasion resistant experiment compared results show, PE pipe abrasion resistant is steel pipe four times.
6 Special construction methods
BAOSU® PE pipe may be used in a few special construction methods, for example trenchless, crossed river, save capital, install faster.
BAOSU® PE pipes are used in water transporting and distribution piping system no more than 40℃, including gas transporting and distribution, water supply, agriculture and irrigation, post and telecommunications, mine, municipal sewage and industrial applications.
PE pipe joining methods
1 Butt Fusion Joining Method
Butt fusion joining method is a simple and fast PE pipe joining method. It is used more than diameter 63mm pipe and pipe joining, pipe and fittings joining.
2 Fitting Joining
BAOSU® PE pipe may be joined by injected fittings, butt fusion prefabricated fittings, steel-plastic joint and other mechanical fittings.
3 Flange Joining
Flange joining is used to join BAOSU® PE pipe and valve, or other material pipe and fittings.
Butt Fusion Joining Procedure
1 SECURE
Clamp the components in the machine. Check alignmentof the ends and adjust as needed.
2 Alignment
The pipe profiles must be rounded and aligned with each other to minimize mismatch (high-low) of the pipe walls. This can be accomplished by tightening clamping jaws until the outside diameters of the pipe ends match. The jaws must not be loosened or the pipe may slip during fusion.
3 FACE
The pipe ends must be faced to establish clean, parallel mating surfaces, interfaces gap<0.3mm. Misplace less than fusion joint thickness 10%. Re-clamp PE pipes must re-face pipe ends.
4 Measure drag force
Every time butt fusion must measure and record drag force.
5 Heat
Heating tools that simultaneously heat both pipe ends are used to accomplish this operation. To ensure that full and proper contact is made between the pipe ends and the heater, the initial contact should be under moderate pressure. After holding the pressure very briefly, it should be released without breaking contact. Continue to hold the components in contact with each other, without force, while a bead of molten polyethylene develops between the heater and the pipe ends. When the proper bead size is formed against the heater surfaces all around the pipe or fitting ends, remove the heater.
6 After the heater tool is removed, quickly inspect the pipe ends, then immediately bring the molten pipe ends together with sufficient fusion force to form a double rollback bead against the pipe wall.
7 Hold Pressure and Cooling
Hold the joint immobile under fusion force until the joint has cooled adequately to develop strength. Allowing proper cooling times under fusion force prior to removal from the clamps of the machine is important in achieving joint integrity.
