Grade: Alloy 600; Alloy 601; Alloy 800; Alloy 825; TP304 ; TP304H ; TP304L ; TP316 ; TP316L; S31803

Standard: ASTM B622; ASTM B516; ASTM B444; ASTM B829, etc

Size :Routine OD : 19.05mm,25.4mm,31.8mm,38.1mm

WT : 1.2-2.77mm

Length : According to customer needs up to 20m

Heat Exchange Tube Production Process :

1 . We use Cold Drawn technology to produce U bend tube

2 . U bend tubes produce will accordance to customer's drawings

3 . To avoid oxidation , inert gas (Argon) is passed through tubes ID at the required flow rate

4 . The radius is checked for its OD and wall thinning with the recommended specification

5 . We'll choose three different position or as customer's require to make sure tubes quality . We'll do physical properties and micro-structure test

6 . Visual inspection for waviness and cracks is done with Dye Penetrant Test

7 . Each tube is then hydro tested at the recommended pressure to check for leakage

Nickel Alloy 625 Heat Exchange Tube Chemical composition: 




Alloy 625 Nickel Alloy Product:

Alloy 625 has excellent strength at temperatures up to 816℃. At higher temperatures, its strength is generally lower than that of other solid solution strengthened alloys. Alloy 625 has good oxidation resistance at temperatures up to 980℃ and shows good resistance to aqueous corrosion, but is relatively moderate compared to other more capable corrosion resistant alloys.

Alloy 625 Tube

Nickel Alloy 625 Tubing, Inconel 625 Pipe is used in short term applications at temperatures up to 816℃.For long term service, it is best restricted to a maximum of 593℃

Nickel Alloy 625 Tubing, Inconel 625 Pipe Product Features:

1. It has excellent corrosion resistance to various corrosive media in oxidation and reduction environment

2. Excellent resistance to pitting and crevice corrosion, and no stress corrosion cracking due to chloride

3. Excellent corrosion resistance to inorganic acids, such as nitric acid, phosphoric acid, sulfuric acid, hydrochloric acid and mixed acid of sulfuric acid and hydrochloric acid

4. Excellent corrosion resistance to mixed solution of various inorganic acids

5. When the temperature reaches 40 ℃, it can show good corrosion resistance in various concentrations of hydrochloric acid solution

6. Good processability and weldability, no cracking sensitivity after welding

7. Manufacturing certification of pressure vessel with wall temperature of - 196-450 ℃
