5 PVC Pipes
Lightweight, cost-effective, and easy to install, PVC Pipes are commonly used in oil and gas operations. Offering
corrosion resistance and high strength, they prove ideal for low-pressure scenarios and are often used in saltwater
disposal, chemical handling, and water flooding.
6 HDPE Pipes
The High-Density Polyethylene (HDPE) Pipes provide excellent resistance to rugged terrains, corrosion, and
chemicals – perfect for cross-country pipelines transporting natural gas. Their light weight and ductility make them
advantageous for seismic-prone areas.
7 Fiberglass Pipes
Fiberglass Pipes, owing to their lightweight, strength, and flexibility, are used extensively in oil field tubulars
and casing for wells. Being resistant to corrosion and demanding less maintenance these pipes are used in
application of oil and gas industry.
8 Copper Pipes
The use case for Copper Pipes extends to handling gases like propane and natural gases needing a tight seal.
Its corrosion resistance and ability to withstand heat make it a perfect fit for this domain.
9 Polyvinylidene Fluoride (PVDF) Pipes
The high purity application of oil and gas makes the PVDF Pipes a viable option, owing to their resistance to most
minerals and aqueous solutions. These pipes also exhibit high abrasion resistance and mechanical strength.
10 Galvanized Pipes
Galvanized Pipes, featuring a protective zinc coating preventing rusting, are effective in transportation of natural
gas and other fluids. Once an industry standard, these pipes while still used, are gradually replaced by less
corrosive materials.
Pipes used in the Oil and Gas industry have diverse properties as follows:

Pipe Types Material Common Uses Advantages
Stainless Steel Steel with Chromium Water Transport, Corrosion Resistance
Petroleum Industries
Carbon Steel Steel with Carbon Transport within Flexible, Durable
