What Are SPI Petro-Pipes?

Petro-Pipes are an oil spill containment solution designed for rainwater discharge in areas with high water tables, poor-draining soil and other challenges. The Petro-Pipe uses an innovative design with 15- to 25-degree slope that generates head pressure and optimizes high-volume flow without vertical drainage.

Petro-Pipes fit into a housing and feature a compressible O-ring that creates a complete seal. Once installed, these pipes can filter media for rainwater and sheen, and they can be cast in concrete, attached to liners and used in bermed areas. With male and female fittings available, Petro-Pipes work for various applications. You can also choose models with or without ball valves.

The following drawings will show just a few ideas on how these products can be used to save time and money on maintenance and the disposal of oily water.


Benefits of Petro-Pipes

With SPI Petro-Pipes, you can benefit from the following:

  • Oil containment: Petro-Pipes work passively 24/7/365 to support oil containment needs and prevent contamination of rainwater.
  • Watertight seal: The compressive O-ring in the system creates a watertight seal that offers comprehensive filtering capabilities.
  • Easy installation: Installation varies based on the Petro-Pipe model, but all models use a simple installation process that’s easy to complete.
  • Quick replacement: Replace Petro-Pipes with ease by swapping out the insert from within a pre-cast flange outer sleeve.
  • Customizability: Petro-Pipes are available in various sizes and adaptable to ball valves, drains, through walls and within many different piping systems. Contact us to discuss customizable options.



Petro-Pipes for Use With Discharge Pipes or Ball Valves

The Petro-Pipe on the left is a PI-620-M4, 6” X 20” with a 4” male fitting. Our PI-620 Petro-Pipes are available with 2”, 3” 4” or 6” male or female connections and are used on the outside of oil containment areas.

They are attached to pipes coming directly from the containment area or attached to ball valves. The Petro-Pipe should always be installed on a 15- to 25-degree slope for best drainage.

Petro-Pipe Used for Drainage with Ball Valves

The PI-620 Petro-Pipe comes with fittings from 2” to 6” (male or female) that are attached to piping or ball valves. The Petro-Pipes have an internal dirt filter and also use a filter basket inside the containment area to block dirt and debris.

Petro-Pipes are used with ball valves to allow rainwater to passively discharge 24/7, removing oil sheen but providing 100% oil containment in an oil spill.

4” Petro-Pipes Used for Oil Containment

The PIT-416 Petro-Pipe is used in smaller applications with a flow rate of about 2.5 gpm and comes with a 1.5”, 2” or 3” male fitting.

These smaller Petro-Pipes do not have an internal dirt filter, so they come with the PCF-44, pre-filter canister. They also require a pre-filter basket on the inside of the oil containment area.

4” x 16” Petro-Pipe Used in Containment Area

In the above photo, the PIT-416 Petro-Pipe is used to contain spills from a diesel generator. The Petro-Pipe utilizes a pre-filter basket on the inside of the containment area to capture the majority of the dirt and debris.

On the outside, the ball valve is left in the open position to drain water 24/7/365.

The pre-filter canister is a secondary dirt filter that is attached right in front of the Petro-Pipe to capture fine dirt and sediment that might make it through the pre-filter basket.

How Do Petro-Pipes Work?

When a high water table, poor-draining soil, or other factors make vertical drainage into the ground difficult or impossible, the discharge of water from a containment area can still be accomplished horizontally using a Petro-Pipe. In these cases, a berm, curb, or wall can be installed to hold back rainwater that might also contain oil. Installing several Petro-Pipes through concrete, asphalt, or earth will trap all the oil while simultaneously allowing uncontaminated water to pass.

Since water drainage occurs best vertically due to gravity, a Petro-Pipe is not as efficient at moving water as a Petro-Barrier™. Therefore, more surface area is required when using Petro-Pipes than when using vertically draining barriers. A 25-degree minimum slope from inlet to discharge is recommended for flow rates of 2.5 to 3 gallons per minute.

Petro-Pipes Are Highly Customizable

Petro-Pipes are available in a variety of sizes according to drainage requirements. They are adaptable to ball valves, drains, through walls, and through a variety of piping systems.

Petro-Pipe Applications and Specifics

The Petro-Pipe can use various configurations. For example, the PIFH-620 Petro-Pipe has a flanged housing that can be cast into concrete. From there, the Petro-Pipe slides into the housing and attaches with fasteners that create a water-tight and oil-tight seal.

The Petro-Pipe has various applications.

For Use With Discharge Pipes or Ball Valves

PI-620 Petro-Pipes are an example of models that attach to pipes coming directly from a containment area or attached to ball valves. These pipes always need to be installed at 15- to 25-degree slope for the best drainage. Our PI-620 Petro-Pipes are available with 2″, 3″, 4″ or 6″ male or female connections for use outside of oil containment areas.

PIFH-620 Petro-Pipe Rainwater Discharging Units

The PIFH-620 Petro-Pipe has a 7″ flanged housing pipe that mounts through a liner or containment wall. It needs to be installed on a 25-degree slope to provide a positive head pressure that creates an optimum flow of 3.5 to 4 gallons per minute.

The Petro-Pipe is installed inside the housing and fastened with five stainless steel screws. An O-ring between the flanges compresses when the screws are tightened to create a water-tight seal. For liner applications, an additional flange is attached to the liner to create a complete seal between the liner and the Petro-Pipe.

A retaining ring located on the inside is removable. This piece features dirt filters that keep the Petro-Pipe clear of debris as it discharges rainwater from containment areas. Dirt filters need changing about once a year. The Petro-Pipe also supports point-source discharge so the systems can be changed out and the filters replaced.
