Ceramic Fiber insulation increases the diameter of the outer wall on Model IVSI-C2 and IVSI-C4 pipe and fittings. Shown in this sequence is the same 8-inch diameter inner pipe. (Photo 1) Without insulation the outside diameter of the pipe is 10-inches. (Photo 2) This is also true of the same pipe with a 1 -inch layer of insulation. (Photo 3) However, the same 8-inch pipe with 2-inch insulation results in an outside diameter of 12 inches. (Photo 4) Adding 4 inches of fiber insulation makes the diameter of the outer wall 16 inches.

Understanding Product Codes and Part Numbers

All parts manufactured by AMPCO are identified by a series of numbers and letters which describe their makeup and function.

Here is how to interpret the Part Number designation for Model VSI and IVSI products.

  1. It begins with the pipe or fitting's Internal Diameter (in inches) such as 8, 22, 36, etc.
  2. This is followed by the Model designation, VSI for air-insulated, or IVSI for parts that are fiber insulated.
  3. Next, is the product's Material designation, such as 316 or 304/304. The first item indicates the makeup of the inner liner, while the second half indicates the material content of the outer wall, if stainless. If aluminized outer, the Part Number indicates inner material only.
  4. Then, following a long dash, the product's Code name is listed, such as AG30, JY, or MVT. If the product is air insulated, the product identification ends with this Code.
  5. Finally, when a product is fiber insulated, a designation is added at the end to indicate Insulation Thickness. -C1 means a thickness of 1 -inch; -C2, 2-inches; and -C4, 4-inches. (For comparison, see photos above.)

Thus, the Ordered Part Number for a 30-inch Adjustable Pipe, with a 6-inch I.D., made of 304 Stainless Steel inner and Aluminized Steel outer, packed with 2-inch fiber insulation, is listed: 6IVSI304- AG30-C2

Note:  For products with reduction or increaser parts, the Part Number changes as follows:

MT and JL - Diameter of Body listed in front of Model VSI or IVSI.
Diameter of Snout listed in front of Code designation
Example - For a Manifold Tee with a 42" dia. Body and 30" dia. Snout:  42VSI304-30MT

OT and OS - Smaller diameter listed first (before Model designation) Larger diameter listed before Code designation
Example - For a Tapered Increaser with an 8" to 16"dia. Body: 42VSI304-30MT

Models IvSI-Z3 (ZC) and IvSI-Z4 (ZC+)

(Photo 1) Adding 3” of ceramic fiber insulation to 8” pipe makes the diameter of the outer wall 14”. (Photo 2) Adding 4” of ceramic fiber insulation to the same 8” pipe makes the diameter of the outer wall 16”.

Understanding Product Codes and Part Numbers

All parts manufactured by AMPCO are identified by a series of numbers and letters which describe their makeup and function.Here is how to interpret the Part Number designation for Model VSI and IVSI products.

  1. It begins with the pipe’s or fitting’s Internal Diameter  (in inches) such as 8, 22, 36, etc.
  2. This is followed by the Model designation or IVSI for parts that are fiber insulated (Model Z3 or Z4).
  3. Next is the product’s Material designation, such as 316 or 304/304. The first item indicates the makeup of the inner liner, while the second half indicates the material content of the outer wall, if stainless. If aluminized outer, the Part Number indicates inner material only.
  4. Then, following a long dash, the product’s Code name is listed, such as AG30, JY, or MVT. If the product is air insulated, the product identification ends with this Code.(For Product Code listings, refer to page 2.)
  5. Finally, when a product is ceramic fiber insulated, a designation is added at the end to indicate Insulation Thickness. Z3, 3”; and Z4, 4”.(For comparison, see photos above.)

Thus, the Ordered Part Number for a 30” Adjustable Pipe, with a 6” I.D., made of 304 Stainless Steel inner and Aluminized Steel outer, packed with 3” ceramic fiber insulation, is listed: 6IVSI304- AG30Z3*

* Note: For products with reduction or increaser parts, the Part Number changes as follows:

MT and JL -  Diameter of Body listed in front of Model VSI or IVSI Diameter of Snout listed in front of Code designationExample - For a Manifold Tee with a 36” dia. Body and 30” dia.

Snout:36IVSI304-30MTZ3

OT and OS -  Smaller diameter listed first (before Model designation) Larger diameter listed before Code designationExample - For a Tapered Increaser with an 8” to 16” dia.
