Product Q&A

Q:What is the working principle of the Venturi tube?

It measures flow based on the pressure difference created when fluid velocity increases and static pressure decreases at the throat, following Bernoulli's equation.

Q:What materials are available for the radiant tubes?

Materials include High Nickel and High Chrome heat resistant alloys, Cobalt base alloys, and various specific grades like HU, HT, HK, HP, HW, and 24/24NbTiZr.

Q:Can the dimensions be customized?

Yes, thickness (5mm, 6mm, 7mm) and length can be customized according to customer requirements.

Q:Is calibration required for all sizes?

No, calibration is not needed for diameters between 50 and 1200. For sizes outside this range, design and manufacture references are used, or real-flow calibration can be performed.

Q:What testing methods are used for quality control?

Testing includes chemical analysis by spectrometer, eddy current test, pressure test, thickness test, 100% liquid penetrant test (PT), and 100% visual inspection (VI).
