Product Details

Pipe Floater:

The hull of MDPE floater is made from medium density polyethylene material with excellent flexibility,filled with high strength polyurethane foam inside.With reasonable becomes the ideal substitution of the traditional steel floater for thr floating dredging pipes.

Structrue:

No.	Structure Name	Material
1	Polyethylene Hull	Polyehylene
2	Hard Polyurethane foam core	Closed-cell Polyurethane foam
3	Steel Bolts	Galvanized carbon steel or 304 stainless steel

Technical Properties of Floater:

Item	Technical Index of Hull	Item	Inside Technical Index
Tensile Strength	≥13.1MPa	Water Absorption	1-2g/100cm2
Break Elongation	≥11.1%	Breaking Strength	0.08-0.1MPa
Impact Strength	≥32.4KJ/m2	Breaking Elongation	4-6%
Bending Strength	≥15.7MPa	Compressive Strength	0.1-0.24MPa
Weather Resistance After total aging energy≥3.5GJ/m2	Break Elongation %≥		10
Weather Resistance After total aging energy≥3.5GJ/m2	Oxidative Induction Time 200°Cmm≥		10

Advantages:

1 It has the property of ultrahigh shock resistance. Becuase it has the impact toughness character in the engineering plastics.

2 Easy to Install and move.

3 Good property of self lubricity and small frictional factor. Self-lubrication better than steel, brass with oil.It can’t form dirt in the medium with PH value of 9 or more, becuase of non-cohesive and non-scaling surface.

4 It helps to raise pipeline substantially.5 It is corrosion-resistant, which can avoid corroding from chemicals. For Example, It can withstand not more than 80% concentration hydrochloric acid 5 It is low temperature-resistant .which can be even used in6 It is also cracking-resistant.It is weather-resistant. Environmental stress cracking resistance is above 4000h (above 2 times of PE100).

7 Long time service, and it can be used for 5-8 years

Usage:

1 It is usually used in dredging project. .

2. It is used in the sea, lake or river on the pipeline
