耐腐食性圧着フィンチューブ、空気側性能の向上とエアクーラー用信頼性の高い機械的結合
Crimped Fin Tube (Helically Tension Wound, Cold-Formed Finned Tube) for Air Coolers Material A Crimped Fin Tube (also called a Spiral Tension Wound / Cold-Formed Finned Tube ) is a heat-transfer tube where a metal fin strip is helically wound under controlled tension onto a base tube . The fin strip is pre-formed to widen the contact “foot,” then mechanically locked to the tube surface (with end fixing such as tack/tag welding or spot welding depending on design). Common
SA178aによってアニールされるASTM A178 ERWの熱交換器の管
ASTM A178 ERW Carbon Steel Boiler and Suoer Heater Tubes Product Description: ASTM A178 is a specification which covers standards for electric resistance welded tubes, which are abbreviated as ERW SA178 Boiler Tube. These ASTM specified SA178a Boiler Tubes are produced with a minimum wall thickness made from carbon steel alloys as well as carbon- manganese steel. This ASTM SA178 Grade A Electric-Resistance Welded Carbon Steel Boiler Tubes are designed to be used in boiler
覆うL型フィンチューブ 炭素型LL型フィンチューブ 螺旋回転のフィンと高熱伝導性
Overlapped L Type Fin Tube Carbon LL Type Finned Tube for Heat Exchanger Product Overview Overlapped L type fin tube, also called LL type finned tube or LL-foot fin tube, is a tension-wound finned tube where L-shaped fins are helically wrapped around a carbon steel base tube and each fin foot overlaps the previous one. This creates a double “L” foot that completely jackets the outer surface of the tube. For carbon LL type fin tubes, the base tube is typically seamless low- or
耐食性熱交換器用アルミニウムL型フットテンション巻L型フィンチューブ
L-Type Fin Tube – Aluminum L-Foot Tension Wound Finned Tubes for Heat Exchanger Material Overview Aluminum L-foot tension wound finned tubes are bi-metallic or multi-metallic heat transfer elements in which a thin aluminum strip is helically wound around a base tube under controlled tension. An “L”-shaped foot is first formed on one edge of the fin strip; this foot bears directly on the outer surface of the tube and mechanically locks the fin to the tube along its full length
ASTM B75 C12200 蒸気追跡用冷引縫いのない銅合金管
ASTM B75 C12200 Copper Alloy Tube High-Quality Copper Alloy Tubes For Steam Tracing Material Description ASTM B75 C12200 copper alloy tube is a seamless, cold-drawn phosphorus-deoxidized copper (Cu-DHP) tube designed for general engineering service and particularly well suited for steam tracing and low- to medium-temperature steam lines. The alloy (UNS C12200 / Cu-DHP) combines: Very high copper purity (≥99.9% Cu including Ag) with 0.015–0.040% phosphorus as a deoxidizer,
Continuously Welded Helical Finned Tube with 30-325 mm Outer Diameter and 6M or Custom Length for Boiler Economizers
Helical Finned Tube — Continuously Welded Spiral ND Steel Fin Tube for Boiler Economizers Material A high-frequency resistance welded helical/spiral finned tube produced with an ND steel (09CrCuSb) base tube and optional ND/carbon/stainless fin strip. ND steel is a Cu–Sb–Cr–alloyed low-alloy steel engineered to resist low-temperature sulfuric-acid dew-point corrosion and chloride attack in flue-gas paths, making it ideal for boiler economizers and air preheaters.
