Air Bags

Product catalog summary

Overview
The document provides technical specifications and applications for inflatable pipeline stoppers, also known as air bags, which are used in various pipeline maintenance and testing scenarios. These stoppers are available in sizes ranging from 2 inches to 84 inches and can be customized with different valve types and materials.

Specifications

Bladders: Made from dipped rubber latex or latex sheet.
Tubing: PVC braided tubing is standard, with lengths of 6 feet for sizes 2" to 18" and 4 feet 6 inches for larger sizes.
Valves: Options include 1/4" BSP female brass flexible tube cock or Schraeder valve. Larger sizes can be equipped with 1/2" ball valves upon request.
Cases: Constructed from PU coated polyester cotton or PU coated nylon.

Applications
Inflatable pipeline stoppers are suitable for pipe testing, oil and gas pipeline maintenance, and drain testing. It is important to note that any physical support can significantly increase the holdback pressure of the stoppers.

Technical Data
The document includes a detailed table listing product references, sizes in inches and millimeters, maximum seal diameters, deflated and inflated lengths, minimum access diameters, maximum inflation pressures in PSI and BAR, unit weights, and quantities per pack for various stopper sizes.

Important Note
Physical support, even if slight, can dramatically enhance the pressure retention capability of the inflatable stoppers.
