Dear experts, we are having a project of aluminum heat exchangers with tube side MOC as aluminum SB 209. Here I want to make confirm the suitable filler wires for TIG welding of Alum...
The fundamental difference between TOFD and PAUT is as follows: TOFD Excellent at detecting and sizing volumetric type indications (i.e. slag, porosity, etc) Good at detecting and sizing p...
Magnetic Particle Testing Magnetic particle testing is a non-destructive testing method for the detection of surface and subsurface discontinuities in ferromagnetic materials. Ferromagnetic ma...
Welding electrode selection is a quite challenging decision because we need to consider many factors while choosing an electrode for a specific project/product. In this post, we discuss the factors ...
Background: A procedure qualification test coupon using the same or different P-Number materials and consisting of two plates of different thicknesses, T2 = 1-1/2” thick and T1 ...
We need to know the way of calculation temperature reduction when we use sub size specimen. Problem: We have tested an A333 Gr.6 (4" pipe-6.3 mm thickness). Laboratory used a s...
Whether Grinding or filling is allowed on the Final pass (on capping) for Welder performance qualification test (WPQT) for Plate or Pipe. Since qualification is done based on ASME Sec IX, so need ref...
This is fastener standard for bolts Grade 8.8 means, Approx. 800 Mpa tensile strength and 640 MPa yield strength (you will arrive at the YS by multiplying both the numbers times 10. That is 8x8x10=...
1) when & why expansion is necessary? Expansion is necessary in all cases because the tube hole in the tube sheet is slightly higher than the tube OD. So if we do not expand it ...
