What is ASME PCC-2?
*ASME PCC-2 stands for the American Society of Mechanical Engineers (ASME) Post Construction Committee 2. It is a standard developed to provide guidelines and procedures for the repair of pressure equipment, including vessels, piping, and related components, after they have been constructed and put into service. ASME PCC-2 covers various aspects of repair, including design, fabrication, inspection, and testing, and it offers recommendations for both temporary and permanent repairs depending on the situation. The standard is widely used in industries where pressure equipment is prevalent, such as petrochemical, oil and gas, power generation, and manufacturing.

Snap It Plugs must be installed exclusively within the rolled section of the tubesheet. If the tubes are not rolled into the tubesheet, contact USA Industries at 1-888-299-2155 for guidance before proceeding further. Before installation, eliminate any scale and pitting using USA Industries’ Snap It Brushes. Additionally, ensure that any weld droop is removed prior to plug installation.

Frequently Asked Questions
The Snap It Sr. tube plug is rated up to 7,000 lbs. of pressure, but with our independent testing, we've seen blowout pressures that exceed 28,000 PSID.
We will make your Snap It tube plug in any exotic or standard metal. The most commonly requested materials include: 70/30 CuNi, 90/10 CuNi, Brass, Carbon Steel, Chrome/Moly, Hastelloy, Inconel, Monel, Nickel 200, Stainless Steel (316 and 304), Titanium, Zirconium and more.
We sell our Snap It plugs in sleeves of 10. There is no maximum. We have the capabilities to produce 5,000 plugs daily, and have more than 500,000 tube plugs of all varieties in stock at all times. Even custom orders, can typically be manufactured and shipped extremely quickly!
These plugs don't require welding, completely removing the risk of a spark igniting dangerous fumes or chemicals.
We strongly suggest never standing in front of an installed tube plug, but Snap It tube plugs, with proper installation, have been independently verified to keep from blowing out at pressures exceeding 28,000 PSID.
Snap It Sr. has five points of contact and Snap It Jr has three. This means that Senior plugs have a much stronger seal (up to 7,000 PSID) and Junior plugs have more flexibility to expand to different size tubes.
Both Snap It Sr. and Snap It Jr. tube plugs require some tools for installation and removal. We strongly suggest using tube brushes to clean and prep your tubes, then installation is a breeze. Our hydraulic ram and pull rod assemblies provide consistent, controlled intallation, eliminating the hazards of tapered and welded plugs, as well as tube and tube sheet damage.
Once you've installed a few Snap Its, you'll find it takes less than 60 seconds to prep and install these tube plugs. Now you can skip welding, and save up to 80% in labor costs with a quick and consistent installation process!
Our Snap It Tube Plugs require ZERO proprietary pieces of equipment to install. Don't get locked into expensive equipment issues after your purchase. Call us and we can confirm your existing tools will work with ours. If not we offer short-term rental and purchase for installation tooling.
Yes, we sell directly to end-users, as well as other contractors and suppliers.
We design, engineer, manufacture, test, and package Snap It Plugs at our facility in South Houston, Texas, and we ship anywhere in the world. As the manufacturer, we are uniquely qualified to provide technical support, certification training, and customizations to meet your specific needs.
Our customers experience competitive pricing and short lead times by dealing directly with USA Industries.
No, Snap It Sr. Tube Plugs are used for "near end" applications only. Because the Snap It Sr plug is designed for higher pressure-holding capabilities, it is unable to expand more than .020". Due to the minimal expansion, this plug is not small enough to travel through the tube for proper installation within the far-side tube sheet.
