Nevada Innerduct Supplier – Smoothwall Innerduct – Nevada Microduct Supplier – Nevada Underground Electrical Duct – Nevada Pipe and Conduit

American Tech Supply is a USA based national distributor with stocking and warehousing providing all major types of BABA innerduct , Buy American Smoothwall innerduct and USA Made innerduct in most standard colors.

Most common diameters range from ¾ and 1 inch smoothwall innerduct, 1.25 inch innerduct, 2 inch smoothwall innerduct, 3 inch innerduct and 4 inch innerduct up to 26 inches in diameter. Smoothwall HDPE is the most commonly used underground raceway and is packaged in continuous lengths on standard and custom reels or coils for corrugated innerduct allowing for fast installation with minimum joints. Smoothwall innerduct can be joined using couplers. Smoothwall innerduct can be installed via trenching, plowing and directional drilling. Smoothwall innerduct is available in numerous colors and stripe combinations for easy identification. There are numerous wall thicknesses available as required for the specific type of installation and application and type of fiber cable, electrical , water, gas or sewage duct.

Smoothwall innerduct also can be orders with ribbed duct allowing for less friction inside the conduit when pulling cable. Traditional innerduct uses pull tape placed into or blown through the conduit between underground vaults placed every 250-1000 feet. The pull tape ranges from 1250 pounds pulling/tensile strength to 6000 pounds.

In todays FTTH or fiber to the home technology the fiber is blown through the conduit up to 2000 feet or more. Furthermore the use of microduct allows a carrier to run multiple types and fibers through a 2 to 4 inch microduct system.

What does SDR stand for?

SDR is the Standard Dimension Ratio. Technically, it is the nominal outside diameter divided by the minimum wall thickness. The larger the SDR, the thinner the wall thickness. See tables (in ASTM F2160, D3485, NEMA TC7 or UL) for standard SDR numbers.d to meet the particular installation methods and ground conditions ranging from SDR. SDR is the Size to Diameter Ratio (or Standard Dimension Ratio), that is, the ratio of the inside diameter (SIDR) or outside diameter (SODR) of the duct or innerduct to the wall thickness of the duct or innerduct. The smaller the SDR number the thicker the wall of the duct.
Smaller SDR numbers also mean that the duct or innerduct has higher tensile strength and greater crush resistance than a comparable product with a higher number.
