For operators who prefer a more traditional approach to socket welding, Aquasol offers Certified 316L Stainless Steel Socket Weld Spacer Ring.

Composed of 316L stainless steel, SteelSpace provides the 1/16″ (1.6 mm) minimum gap required by US Navy & Military Codes and is known as the “Marine Grade” for its increased resistance to corrosion.

SteelSpace effectively does away with scribing, measuring, and fitting and helps to reduce and eliminate cracked welds.

SteelSpace, available in a variety of sizes ranging from ½” to 2″ in diameter, is designed with spring action to firmly secure itself in place during and after welding, as it becomes a permanent part of the joint. SteelSpace provides a reliable, easy-to-use solution that is ideal for use in the food, pharmaceutical, nuclear, and aerospace industries.

How SteelSpace Works


Squeeze outer edges of ring slightly to decrease outer diameter temporarily

Push in Place

Push ring inside pipe and release, allowing spring action to position securely against socket


Once aligned against inner socket wall, commence welding, allowing the spacer to permanently become part of the joint


  1. Tack weld 3 or 4 times maintaining proper interpass temperature as specified by ASME B31.3 or welding engineer
  2. Square up the pipe after the first tack
  3. Proceed to weld without exceeding interpass temperature
