This type of pipeline pig is totally made from polyurethane material and treated by laminated membrance.

Pipeline Pig

The rubber cup is made from polyurethane material and treated by laminated membrance. The surface of it is lucidus and has no bubble or crack.

By using folded edge, the wear resistence is improved by 30% without increaseing interference. The big enough folded edge, thickness and interference of the cup ensure that the pig will not distort for its own weight.

The installation of different hardness cups achieves leak tightness, cleaning effect, passing ability and avoidance of extra support, which make best integrating performance.

The cups interference range relative to the inner face of pipeline is 4%--7%.The physical property meets requirements as follows:

No.	Technical Item	Unit	Index
1	Hardness	HS	80±5
2	Tensile Strength	MPa	>40
3	Permanent Deformation	%	<10
4	Peel Strength	KN/m	>70
5	Akron Abrasion	Cm3/1.61KM	<0.01
6	Temp. Range		-40+90
7	Tensile Rate	%	>500
8	Specific Gravity	g/cm3	1.26
9	Rebound Rate	%	>15
