Heated Sample Line

Heated Sample Line Finishes (Grades)

• Heat Trace Only: The most simple offering. Heat tape is wrapped around tubing. Heat tape is electrically terminated and ready to heat, with accessories/options requested by customer already installed (Plug or lead wires, thermostats and/or thermocouples or other temperature controls). Customer will be responsible for protecting tube/tape and user by providing thermal insulation and possibly a moisture barrier, depending on environment.) Recommended for lab use as is or built-up by customer for use in other environments.
• Heat Trace With Heat Shrink: Same as above, with the addition of a clear heat shrink material over the length of the heated section of the tubing. Polyolefin heat shrink is standard and it is rated to 275ºF (~135ºC). If higher temperatures are required, Teflon shrink must be used, which incurs a substitute material surcharge. Either heat shrink provides no thermal insulating qualities, but does offer increased protection from moisture and/or contaminants. Recommended for indoor use.
• Heavy Duty: Heated Sample Line is heat traced and covered with one or more layers of 1/4” Nomex felt insulation (multiple layers of insulation will increase cost). The insulation is then held in place with Nylon braid. End of heated section sealed using black heat shrink tubing. Recommended for indoor use in varying temperature environments or where a large rise in temperature is desired.
• Industrial Strength: The most robust offering. Same as the heavy duty finish with the addition of what we call Scuff coat. Scuff coat can be described as looking similar to a plastic fire hose and provides excellent resistance to moisture and/or exterior contaminants, as well as slightly increasing the thermal insulating qualities (Scuff coat is basically extruded silicone over fiberglass braid). Recommended for outdoor use or where extreme rise in temperature is desired.
• Tuff Guard: This high strength, extremely durable exterior cover offers superior heated sample line protection with one third less weight, setting a new standard in the marketplace. Tuff Guard is resistant to alcohol, grease, minerals oils, diesel oil, petrol and is self-extinguishing. The flexible nature of Tuff Guard’s corrugated construction allows it to be easily coiled and stored. Produced within ISO 9001 guidelines, Tuff Guard can also be fitted with an extra layer of high-temperature protection when testing inside smokestacks. Tuff Guard abrasion resistance means long lasting durability in the field, and its lighter weight means ease of use for the operator.
• Tuff Guard Extreme: This is Clayborn's most robust finish. Looks and feels very similar to standard Tuff Guard, however uses a polyamide 12 rather than polyamide 6. This allows greater resistance to higher temperatures, lower temperatures, as well as very dynamic applications like robotics.
