INDUSTRIAL PIPING SYSTEMS

Your end-to-end industrial piping solution

Viega press fittings and valves have more approvals than any press fitting manufacturer in the industry.
That means that from 1⁄2" all the way up to 4" in multiple alloys, including stainless steel, you have all the configurations you need. Viega press technology lets you make safe, secure connections in seconds – without a flame. And our Smart Connect® technology instantly identifies unpressed connections – so you can build and commission on the same day. If MRO is the name of your game, Viega helps you make repairs in seconds.

Design with Confidence

In 2024, The American Society of Mechanical Engineers (ASME) has given B31 Board approval to Viega to include ASTM F3226 Metallic Press-Connect Fittings as a listed component. The code includes several sections – Power Piping, Process Piping and Building Services Piping – where Viega ProPress® and MegaPress® systems are approved listed components. That means from new builds to timely repairs, engineers can have total confidence using Viega in industrial settings.

Benefits of Viega Press Technology

Eliminate Hot Work

Soldering and welding equipment is responsible for nearly 1,200 fires causing $150 million dollars in property damage*. Viega press fittings require no open flames or hot work permits.

Reliable + Quality Installation

Unlike grooved or threaded connections that reduce pipe wall thickness, Viega fittings preserve pipe integrity. All of our fittings come factory assembled for maximum consistency in the field.

Faster, Consistent Connections

A simple 11-joint assembly takes just under 11 minutes to press*. Compare that to more than two-and-a-half hours of welding and you’re talking about some serious cost savings.

Reduce Downtime

When unplanned downtime can cost hundreds of thousands of dollars every hour, you need a product that can get you up and running faster. Viega press fittings reduce install time by up to 90%.

Make planned downtime a success

Rand Whitney believes it – after swapping the traditional planned downtime method for 4" Viega MegaPress Stainless. See how this 24-hour manufacturing facility was able to save a day of labor on a recent repair.

Ken’s Food Facility in Lebanon, Indiana

Everybody knows the best wings start in Lebanon, Indiana at the Ken’s Food facility where Sweet Baby Rays BBQ Sauce is made.

Using Viega ProPress and ProPress Stainless ½” – 2” fittings allowed Greiner Brothers Contractors to get chilled water, compressed & instrument air and process water lines Installed quickly.

North Alabama Medical Center in Florence, Alabama.

With an aggressive construction schedule – just 23 months to build a 485,000-square foot, five-story hospital – contractors knew that speedy installation was a must. Viega had the answer.

You can find both our ProPress and MegaPress fittings throughout the North Alabama Medical Center in a variety of sizes from 1/2” all the way up to 4”. It’s the go-to for Layton Construction (General contractor) and MMC (Mechanical contractor) when the entire community is relying on its hospital opening on-time.

Press technology speeds up massive 53-story mixed-use high rise build

“We are always required to have fire watches when we have an open flame and torch with soldering, so then we have to schedule watch guys and all of that,” said Steve Thompson, General Foreman for EM Duggan in Boston, Massachusetts. “ProPress helps eliminate that. And with MegaPress, we can eliminate the fire watches needed for welding, so both products are a time saver for us.”

ProPress fittings were used on the potable water system, hot water return and hot/cold lines along with a rainwater reclamation system. MegaPress pipe fittings were the choice for all the natural gas piping in the building and throughout the mechanical rooms.

100-year-old steel plant completely
rebuilds furnace in 9 weeks

When a large steel manufacturer had to install 3,000 feet of 1 1/2” pipe and 5,000 feet of 2” pipe in just over two months, traditional methods simply weren’t fast enough.

Viega press fittings ensured that the project took week less to complete and had the plant’s furnace operating at full capacity reliably.
