Sealing rope for pole | Non-Rotting | Mold gap filler rope In Stock

Sealing rope for pole | Non-Rotting | Mold gap filler rope

The main function of the Sealing rope for pole is to prevent leakage of centrifugal pipe piles and pole molds.

Spec: 6/8mm

Color: black

Material: cotton

Weight: 37~40kg/bundle

Packaging: waterproof packaging bag

Sealing Mechanism:

Sealing rope for pole is placed in the dovetail groove of the lower mold. When the upper mold closes, its protruding dovetail compresses the rope against the lower groove, forming a sealed contact. This prevents slurry leakage during centrifugation, ensuring:

Elimination of honeycombing defects in pile concrete

Prevention of product rejection due to leakage-induced voids

Why Sealing rope for pole is Essential?

During pipe pile production, concrete mixture is poured into the lower steel mold half. The upper mold half is then positioned, and the assembly undergoes high-speed centrifugal spinning.

Function of sealing rope for pole :

Cotton rope primarily prevents slurry from leaking out of the mold.
How to Use Sealing rope:

Prevent the mold opening, then close the mold, pressing the cotton rope between the upper and lower mold openings.

Specifications:

Sealing rope comes in different thicknesses, with 13 and 17 strands.

Disadvantages of straw rope and advantages of Sealing rope for pole :

Property	Straw Rope	Cotton Rope
Water Absorption	Low, prone to slurry leakage.	High, resistant to slurry leakage.
Thickness	Irregular thickness, prone to slurry leakage.	Uniform thickness, ensures effective sealing.
Tensile Strength	Low strength, easily breaks; operational hazards.	High toughness, breakage-resistant; ensures operational safety.
Storage	Requires large space; high freight/storage costs.	Space requirement: 50% of straw rope; low freight/storage costs.
Shelf Life	Dry but fire-prone; rots when damp; short shelf life.	Fire-resistant and rot-proof; long shelf life.
Actual Cost	High defect rate; material waste and low labor efficiency; high actual cost.	High labor efficiency; low actual cost.
