Akshar precision tubes Pvt. Ltd. Chhani Road, Vadodara, Gujarat

Welded square fin tubes these resistance welding processes produce a strong metallurgical bond between the fin and the tube while minimizing the heat affected zone (haz) in the tube. The use of pressure to forge the square fins and the tube together helps to minimize the heat input necessary to make the weld.

Materials :Carbon Steel, Stainless Steel, Duplex & Super Duplex Steel, Alloy Steels (P5,P9,P11, P22), Inconel, High Chrome High Nickle & Incolloy Etc. (any Ferrous Material), Stud Diameter : Standard Size Is Circular For Extended Portion 0.5” (12.7MM) (can Be Changed As Per Customer Requirement)

Materials : Carbon Steel, Stainless Steel, Duplex & Super Duplex Steel, Alloy Steels (P5,P9,P11, P22), Inconel, High Chrome High Nickle & Incolloy Etc. (any Ferrous Material), Stud Materials : Carbon Steel, Stainless Steel And Alloy Steel (Any Ferrous Material)

4 No Of Machines (lines ) With A Capacity To Manufacture 20,00,000 Mtrs Of High Frequency Welded Fin Tubes Per Annum.This Is The Highest Capacity In India (can Be Increased).Fins Thickness : Min. 0.8 Mm To Max. 3 Mm In Cs Fin & 1 Mm To 2.5 Mm In Ss

Oval Stud Welded Elliptical Stud Tubes Pressure To Forge The Oval Stud And The Tube Together At The Point Of Maximum Heating Is Applied By Various Forms Of Tooling. These Resistance Welding Processes Produce A Strong Metallurgical Bond Between The Stud And The Tube While Minimizing The Heat Affected Zone (HAZ) In The Tube.

Non pressure parts of non pressure parts for above products like support structure, transportation & lifting structuress upto 150 tons, columns & beams for site installation, piping support structures, etc.

High frequency welded spiral fin tubes this is important in maintaining negligible resistance to heat transfer between the fin and tube. Hf welded fins shows less extensive heat affected zone, the affected depth is minimal when compared to other types of welding.

Heat Recovery Steam Generation (HRSG) Modules The Entire Job Along With Drilling, Grooving, Tube Bending Etc. We Can Work On All Types Material Like Cs (regular & Nace) , Ms, Ss (304, 316, 310, 410, 321 Etc) Las (P5, P9, P11,P22), Special Material Like Inconel & Incoloy , Duplex & Super Duplex Steels

Heat Exchangers & Pressure Parts All Under Tpi Inspections As Per The Astm & Asme Codes Is All Metallurgy Like Ms, Ss, Alloy Steel, Non Ferrous Material Like Aluminum,

An Electric Current Is Applied By Contacts On The Square Fins (by Using Special Contours) And Tube And The Resistance In This Circuit Produces The Heat Necessary For Welding. Maximum Resistance And Therefore Maximum Heating Occur At The Interface Between The Fin And The Tube. Pressure To Forge The Square Fins And The Tube Together At The Point Of Maximum Heating Is Applied By Various Forms Of Tooling. These Resistance Welding Processes Produce A Strong Metallurgical Bond Between The Fin And The Tube While Minimizing The Heat Affected Zone (HAZ) In The Tube.

Thickness : 2mm To Max 4 Mm

Convection Modules And Economisers Modules Upto 110 Metric Tons Single Pieces In All Types Of Metallurgy We Can Work On All Types Material Like Cs (regular & Nace) , Ms, Ss (304, 316, 310, 410, 321 Etc) Las (P5, P9, P11,P22), Special Material Like Inconel & Incoloy , Duplex & Super Duplex Steels.
