## Abstract

A scraping element for a pipeline pig, includes a moulded body having a circular peripheral scraping edge circumscribing the body and adapted to engage an interior surface of a pipeline. The body is adapted to be mounted to a pipeline pig. A wear resistance material embedded in the scraping edge of the body.

## Claims

### Claim 1

A scraping element for a pipeline pig, comprising:
a moulded body having a circular peripheral scraping edge circumscribing the body and adapted to engage an interior surface of a pipeline;
means for mounting the body to a pipeline pig;
a wear resistant material embedded in the scraping edge of the body.

### Claim 2 (depends on 1)

The scraping element of claim 1, wherein the wear strips are positioned in parallel spaced relation around a circumference of the body.

### Claim 3 (depends on 1)

The scraping element of claim 1, wherein the body is of urethane.

### Claim 4 (depends on 1)

The scraping element of claim 1, wherein the wear resistant material is selected from a group consisting of an ultra high molecular weight polyethylene, a thermo-plastic, a thermo-set, a carbon-based material, kevlar, nylon, and ceramic.

### Claim 5 (depends on 1)

The scraping element of claim 1, wherein the body is disk-shaped.

### Claim 6 (depends on 1)

The scraping element of claim 1, wherein the body is cup-shaped.

### Claim 7 (depends on 1)

The scraping element of claim 1, wherein the wear resistant material is in the form of a belt having a plurality of upstanding ribs that serve as wear strips.

### Claim 8 (depends on 1)

The scraping element of claim 1, wherein the wear resistant material is particles.

### Claim 9

A scraping element for a pipeline pig, comprising:
a disk-shaped body moulded out of urethane having a circular peripheral scraping edge circumscribing the body and adapted to engage an interior surface of a pipeline;
means for mounting the body to a pipeline pig;
a belt embedded in the scraping edge of the body, the belt being made from a wear-resistant material selected from a group consisting of an ultra high molecular weight polyethylene, a thermo-plastic, a thermo-set, a carbon-based material, kevlar, nylon, and ceramic, the belt having a plurality of upstanding ribs that serve as wear strips, the wear strips being positioned in parallel spaced relation around a circumference of the body.

### Claim 10

A scraping element for a pipeline pig, comprising:
a cup-shaped body moulded out of urethane having a circular peripheral scraping edge circumscribing the body and adapted to engage an interior surface of a pipeline;
means for mounting the body to a pipeline pig;
a belt embedded in the scraping edge of the body, the belt being made from a wear-resistant material selected from a group consisting of ultra high molecular weight polyethylene, thermo-plastic, thermo-set, a carbon-based material, kevlar, nylon, and ceramic, the belt having a plurality of upstanding ribs that serve as wear strips, the wear strips being positioned in parallel spaced relation around a circumference of the body.

### Claim 11

A scraping element for a pipeline pig, comprising:
a moulded body having a circular peripheral scraping edge circumscribing the body and adapted to engage an interior surface of a pipeline;
means for mounting the body to a pipeline pig;
particles of wear-resistant material embedded in the scraping edge of the body.
