Orangeburg Pipe: A Lousy Choice from the 1950s that Still Plagues Modern Plumbing

Have you ever faced the frustration of having to replace an Orangeburg pipe, only to wonder why such a poorly performing material was so widely used during the mid-20th century? In this article, we will explore the historical context, the reasons for its widespread use, and the myriad of issues associated with this material.

Historical Background and Usage

Orangeburg pipe made from a type of asphalt-impregnated fiber was commonly used in the mid-20th century for sewer and drainage systems. This type of pipe was a popular choice during the 1950s and was widely used to construct infrastructure, especially during a time when metallic materials were in short supply.

Cost-Effectiveness

One of the main reasons for its popularity was its cost-effectiveness. Orangeburg pipe was relatively inexpensive to produce and install compared to other materials like clay or metal. This made it an attractive option for municipalities looking to minimize capital expenses on infrastructure projects.

Lightweight and Easy to Handle

The material was also lightweight, which simplified transportation and installation. This was crucial considering the demand for rapid infrastructure development following World War II. Contractors preferred the ease of handling this lightweight material over the heavier alternatives.

Availability and Flexibility

During the post-World War II era, there was a high demand for infrastructure development, and Orangeburg pipe was readily available. In addition, the design of these pipes allowed for some flexibility, which was beneficial in certain soil conditions. These practical considerations made Orangeburg pipe a favored choice at the time.

Impact on Modern Plumbing

While these factors contributed to the widespread use of Orangeburg pipe, the material has significant downsides. Its susceptibility to deterioration, cracking, and tree root infiltration can lead to costly repairs and replacements. Unfortunately, by the late 20th century, the use of Orangeburg pipe declined significantly as better materials like PVC and HDPE became more available and cost-effective.

A Close Look at Orangeburg Pipe

The Boring Historical Story

Orangeburg pipe was initially made from "fiber and bituminous pitch," essentially "compressed or laminated tar paper." This material was used for electrical conduit in historical structures such as the Empire State Building. As demand for piping in sewer and plumbing applications grew, Orangeburg pipe was adapted into cylindrical tubes. It became especially popular during World War II due to the metal shortage and remained a viable option even after the war, contributing to the development of affordable housing during the Baby Boomer era.

Design Genius

Orangeburg pipe was also marketed using a genius design. When installed, Orangeburg pipes and fittings required no messy cements or glues, as everything was impregnated with pitch tar. This allowed for a complete and permanent bond by simply banging the fittings onto the pipes, streamlining the installation process. However, this marketing genius didn’t quite live up to real-world conditions.

Real-World Failures

Unfortunately, the real-world performance of Orangeburg pipe was prone to failure. Laboratory testing highlighted its impressive properties, but real-world conditions revealed that there were two main factors that lab testing failed to predict. First, improperly bedding the pipes could cause excessive external strain, leading to failure. Second, harmful chemicals in drain water could cause internal delamination and weaken the pipes from the inside out. These errors in design and testing have resulted in often-paralyzed pipes, delamination, and crumbling, alongside frequent root intrusions.

Contemporary Plumbing Solutions

While many are left with the misfortune of owning property with Orangeburg pipe, there are still options available. Sometimes these pipes can be spot-repaired and maintained, allowing homeowners to save money for a complete replacement. Skilled plumbers like myself can help with these repairs, ensuring that the pipes last for several years, sometimes even up to a decade.

In conclusion, Orangeburg pipe, despite its initial appeal, has proven to be a suboptimal choice for modern plumbing. Its use declined as better materials became available, but its legacy continues to cause issues for many homeowners and plumbers alike. For those dealing with Orangeburg pipe, it is crucial to understand its history and the factors that contributed to its failure, so you can make informed decisions about repairs and replacements.
