ASTM b705 pipe

ASTM b705 pipe

Inconel alloys helped produce Whittle turbo engines in the 1940s has been used for the past ninety years for making pipes and tubes. There are different Inconel alloys as per the chemical composition of nickel-chromium primarily. Also, there are elements like iron, molybdenum, cobalt, niobium, and others.

ASTM B705 are the specifications for the correct chemical composition of many Inconel alloys. ASTM B705 specified pipes and tubes have excellent properties to be helpful in sensitive applications. A few of the applications include the turbo systems of flights and Formula 1 cars.

Though ASTM B705 and A514 are specifications for nickel alloys, the difference is in their composition. A few of the differences between the two include the following among others.

  • A 514 has less than 50% nickel content. Also, ASTM B705 specifications cover the Inconel superalloys, whereas A514 covers Incoloy alloys.
  • A514 covering alloys have high iron content than B705 specification covering alloys, and hence the corrosion resistance of ASTM B705 is more than that of A514
  • A 514 covering Incoloy 800 has more chromium than the Inconel alloys to increase its corrosion resistance.

ASTM B705 specification covers nickel-alloy welded pipes in the annealed condition. The three pipes covered under the ASTM B705 specification include the following.

  • UNS N06625 or NAS 625, or NCF625 is an Inconel 625 superalloy which is a nickel-chromium-molybdenum alloy with niobium to have high strength and resistance to a wide range of extreme corrosion environments
  • UNS N06219 is a nickel-chromium-molybdenum-silicon alloy that also has aluminum, iron, manganese, and others in small quantities
  • UNS N08825 NAS 825 NCF 825 is an austenitic nickel-iron-chromium alloy with titanium, copper, molybdenum, and others to have exceptional corrosion resistance in both oxidizing and reducing environments

Buy ASME sb 705 pipe from the most experienced GCC countries traders with 100% sample preservation, and discover the manufacturing process.

ASTM B705 welded pipe manufacturing begins by welding large sheets of Inconel superalloy using longitudinal weld steam. The automatic welding process of the flat rolled alloys produces cost-effective welded ASTM B705 tubing for use in many sectors.

Delivery of the welded tube complying with the ASTM B705 specifications is after annealing treatment to re-establish the flexibility after the cold working method. Also, it prevents cracking as additional mechanical stress from the pipes gets relieved during the annealing process. It also prevents welded pipe distortion because of the machining and grinding in high temperatures.

Get the best deal by chatting with authorized ASTM b705 welded pipe distributors today via live chat and viewing the testing procedure.

ASME SB 705 pipe is best used in high-temperature and mechanical stress applications that also need high surface stability. Hence, many NDT or non-destructive tests are conducted on ASME SB705 nickel alloy welded pipe. A few of the tests include the following, among others.

  • Mechanical Testing like Tensile of Area
  • Hardness Test
  • Chemical Analysis or Spectro Analysis
  • PMI Testing or Positive Material Identification testing
  • Flaring & Flattening Test
  • Micro and Macro Tests
  • Pitting Resistance Test
  • IGC or Intergranular Corrosion Test

All the above tests do not damage the pipes and tubes but ensure delivery without any defects suitable for specific applications.

Are you unhappy with the price of your current ASTM b705 tubing supplier? Review the solution and discover the reasons why ASTM b705 pipe leaks occur.

ASTM B705 pipe leakage can cause extensive damage to its many applications in several sectors. Hence reputed pipe suppliers conduct many leak tests like hydrostatic or pneumatic tests to ensure pipes do not have any leakages. There are many causes for pipe leakages, including the following, among others.

  • Corrosion is the number one cause of most pipe leakages in domestic, commercial, and industrial uses, as the rust leads to cracks in the pipes
  • High temperature and pressure environments that the pipe operate is the second major cause for leakages
