HVAC & Mechanical Piping Materials and Methods

A Comprehensive Overview of Mechanical Piping System Types & Materials

Mechanical piping systems are integral components that efficiently transport fluids such as water, steam, natural gas, and chemicals. This guide explores the various types of mechanical piping, the materials used, and the crucial role of pipe fittings.

Types of HVAC & Mechanical Piping

Different types of mechanical piping serve specific purposes in commercial and industrial settings. Here are some common types:

Steam Piping

Steam piping transports the steam generated by boilers for diverse applications, including heating, cooking, and sterilization.

Water Piping

Water piping (often called hydronic piping) transports heating water from a boiler, or chilled water from a chiller, throughout a facility’s heating and cooling systems.

Natural Gas Piping

Natural gas piping transports natural gas from municipalities to equipment and is used in numerous commercial and industrial facilities for heating and process applications.

Process Piping

Process piping facilitates the transportation of chemicals and other fluids essential to the manufacturing process.

Compressed Air Piping

Compressed air piping carries compressed air from one part of a workshop to another.

Pipe Materials

Mechanical piping can be constructed from various materials, each chosen based on specific facility requirements:

Carbon Steel

Carbon steel, which is durable and cost-effective, is a common material in mechanical piping.

Stainless Steel

Highly corrosion-resistant stainless steel is preferred in facilities dealing with highly corrosive fluids.


Brass pipes & fittings are typically used for carrying water, chemicals, flammable gases, slurries, and other substances.


With excellent heat and electricity conductivity, copper is often used in piping for heating and cooling systems.

MDPE (Medium-Density Polyethylene)

MDPE typically replaces traditional copper pipes, saving time and installation costs. It is often used for water and underground natural gas piping.

PVC (Polyvinyl Chloride)

Lightweight and cost-effective, PVC is a popular choice for water and air systems.

Polypropylene (PP)

Polypropylene is the perfect piping material for all types of pressurized mechanical and plumbing systems.

Pipe Fittings

Pipe fittings connect and control fluid flow within a mechanical system. Several types of fittings include:

  • Elbows: Change the direction of the pipe.
  • Tees: Split the flow of fluid in two directions.
  • Reducers: Connect pipes of different sizes.
  • Couplings: Connect two pipes.

Specialty Pipe Fitting Types

SyncQuip Mechanical utilizes many specialty pipe fitting types to speed up installation times, saving our customers money over conventional piping methods.

Copper Press Fittings

Copper press fittings are often used to connect copper pipes without conventional brazing or soldering methods.

MegaPress Fittings

MegaPress is faster, safer, and more secure than traditional methods of joining pipes. On average, each press connection takes under 10 seconds. MegaPress is approved for more than 800 applications, including fuel oil, compressed air, water, and steam.

MegaPressG Fittings

MegaPressG is engineered explicitly for heat, oil, and chemical exposure and is the first fitting approved for connecting gas pipes up to 4″.

ACR Copper Press Fittings

Made from Refrigerant-Grade Copper, Press Fittings lets you create a permanent and reliable mechanical connection in 10 seconds without brazing.

ACR Rectorseal PRO-Fit Quick Connect

PRO-Fit Quick Connect are push-to-connect, flame-free fittings for connecting refrigerant lines. For HVAC/R applications up to 870 psi (60 bar).


Made from lightweight aluminum, Unipipe Solutions features fittings that are 5X more secure and with a wider range of sizes than any other piping system. Unipipe comes in 13 sizes, from ¾” to 10”, perfect for compressed air and available applications like multi-fluid, vacuum, high pressure, and nitrogen systems. Unipipe Air is rated for systems with a max working pressure of 232 PSI (16 bar).


Made from heavy-wall aluminum, Unipipe HP is rated for applications with a Maximum Working Pressure of 1015 PSI (70 bar).
