ASTM A193 Scope
Originally approved in 1936, this specification is heavily utilized in petroleum and chemical construction applications. The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high pressure service. This specification includes fasteners intended for use in pressure vessels, valves, flanges, and fittings. Although, this material is often available in national coarse (UNC) thread pitches, if being used in traditional applications, threads are specified 8 threads per inch (tpi) for diameters above one inch.
Below is a basic summary of a few of the common grades. ASTM A193 covers a number of other standard specifications not covered in this description including B5, B6, and B16.

Pneumatic Tube Supports: Tray Mount
In addition to our stud mount pneumatic pipe supports and hangers, PFS also carries PTCB-type tray mount pneumatic tube supports. Simple to install, these tube supports will get the job done where stud mount supports won’t.
Available in grade 316 stainless steel or aluminum, according to your preference, PFS’s tray mount supports allow for pneumatic tube systems to use cable tray walls for support. Our PTCB-type tray mount pneumatic tube supports work by fastening mechanically to the outer wall of trays; they are compatible with both B-Line cable trays and fiberglass channel trays. Both the B-Line-compatible tray mount and the fiberglass-compatible mounts can be used with standard tubing line clamps.
Because our tray mounts are designed for easy installation, the only hardware needed to fasten them is a 1/4-20 SS316 hex head bolt, a 1/4-20 SS316 flat washer, and a nylon insert lock nut. These pieces of hardware are included with every PFS tray mount tube support order.
PFS’s tray mount pneumatic tube supports are:
Quick and simple to install (supports fasten easily onto cable trays)
Made of corrosion-resistant grade 316 stainless steel (or aluminum, if preferred)
Available in two sizes (B-Line: 4 in. and 6 in.; fiberglass: 6 in. and 8 in.)
Our customers in the shipbuilding, offshore platform, and steel fabrication industries depend upon their pneumatic tubing, which is why we provide the most reliable, functional tray mount designs possible-in the most corrosion-resistant materials available.
