Pipe Types - Raleigh Boring

Carrier, carrier pipe, casing, channels, conduit, ducts, product pipe, sleeve and tunnels are all terms used to describe pipes used in utility construction.

The following terms are often used in underground utility construction industry:

Carrier Pipe:

The tube which carries the product being transported and which may go through casings at highway and railroad crossings. It may be made of steel, concrete, clay, glassfiber reinforced polyester, plastic, ductile iron, or other materials. On occasion it may be bored direct under the highways and railroads.

Casing Pipe:

A pipe installed as external protection to a Product Pipe or Carrier Pipe.

Conduit:

A broad term that can include pipe, casing, tunnels, ducts, or channels. The term is so broad that it should not be used as a technical term in boring or tunneling.

Duct:

In many instances, a term interchangeable with pipe. In the boring industry, it is usually used for small plastic or steel pipes that enclose wires or cables for electrical or communication usage.

Cased Bore:

A bore in which a pipe, usually a steel sleeve, is inserted simultaneously with the boring operation. Usually associated with Auger Boring.

Casing Pipe:

A pipe installed as external protection to a Product Pipe or Carrier Pipe.

Carrier Pipe:

Wrapped Casing (Wrapped Pipe):

A coating on pipe for protection from corrosion, usually composed of asphalt and asphalt coated paper. Some coatings may contain plastic, fiberglass, coal tar, or other materials.

Raleigh Boring Underground Construction | Underground Utility Construction Pipe Reel

Every underground utility installation project requires some type of pipe.

We use our reel trailers to transport both small and large pipe reels from our pipe suppliers to your project.

Raleigh Boring Underground Construction | Underground Utility Construction Pit

Construction Pit Preparation: Before our workers can enter an underground utility construction pit, we establish a pre-entry construction pit plan.

First we have a competent person evaluate the work site for the presence of confined spaces, including permit-required confined spaces.

Once the space is classified as a permit-required confined space, we identify the means of entry and exit, proper ventilation methods, and elimination or control of all potential hazards in the space.

We then ensure that the air in a confined space is tested, before workers enter, for oxygen levels, flammable and toxic substances, and stratified atmospheres.

If the air in a pit is not safe for workers, we ventilate or using whatever controls or protections are necessary to ensure our employees can safely work in the space.

After our pre-entry plan is completed, we then monitor the space for hazards, especially atmospheric hazards.

We also have attendants stand outside construction pits to make sure that unauthorized workers do not enter them.
