THERMO TECH TUBE® TYPE S (Single tubing bundle)

Introduction

Thermotech Tube® provides ideal solution to make highly economic and high-efficiency steam or other fluid transfer system through a plant and is intended to replace hard piping and field-installed insulation and especially, used steam distribution lead line and condensate collecting lead line of petrochemical, refinery’s steam tracing system. Thermotech Tube® provides customer’s energy and cost saving and convenient construction work.

Usage/Application

Steam supply line, Condensate collecting lead line, Instrument Impulse line, On-line Analyzer Sampling line etc

Rating & Performance

Thermotech Tube® Type S maintains outer jacket temperature(personnel protection temperature) under 60℃ and maintains inner process (fluid) temperature over 204℃. CM TECH Bundle’s insulation material (glassfiber, aerogel) endures over 1200°F (649°C), each size marks metric and imperial unit. For more information, See the Performance data pages.

TUBE SPECIFICATION.

CM TECH’s standard tubing materials are 304/304L semi-seamless and 316/316L seamless stainless steel, type 1220 copper tube. In case of using other materials, available upon requested. Regarding Selection of Process tube and Steam tube material, CM TECH recommended that using same tube material for bundle. This prevent from twisting bundle tube by heat expansion. CM TECH recommended using same tube materials for bundle.

Common Tube Materials and Sizes

Basically, CM TECH’s standard tubing sizes are 1/4”, 3/8”, 1/2”, 3/4”. The most widely used material is 304/304L ASTM A269, and Copper type #122 DHP seamless ASTM B68 also available. In case of using other material, CM TECH can supply those materials within ASTM STANDARD. (See Technical Specification Chart.)

Insulation

CM TECH using Non-hygroscopic glassfiber insulation and Aerogel for tubing buldles. Specially using Aerogel insulation for high temperature process over 400℃. For more specific insulaton specification, see 3. Insulation/jacket specification section.

Outer FR-PVC jacket

Frame-resistant PVC(FR-PVC) Jacket protects the tubing against corrosive atmospheres, water, oils, acids, alkalies and most chemicals. Min./Max. allowable exposure temperature is -50~102℃, allowable surface temperature is 82℃.

Accessories

CM-ESS-0 : Jacket Patch Kit

CM-ESH-01 : Entry Seal Kit

CM ESS-02/03/04 : Heat Shrinkable Boots

*For more information, See the Accessories section.

Testing

Every CM TECH’s tubing products are pressure tested before shipment. If required, 3rd party test or inspection is also possible and which include DNV, ABS & LLOYD’S REGISTER standard. For more information, ask factory’s Q/A manager. (Reference : CM-B-301 Inspection and test plan)

NOTE

It is necessary to seal the ends that prevent from contamination by moisture and(or) corrosive liquids. CM TECH supplies Sealing tools for end works. For more information, See the accessories pages.
