Support the use of 304 stainless steel potion detection2. Support chemical composition analysis spectrometerWhy can't the threads connect1. Different thread standardsUsually thread standards are NPT,BSPT, Metric.Some threads are non-standard and the standards of each thread cannot be used with each other2.Thread profile differentHow to measure thread correctlyTaper thread, will be more and more tight when rotating, tight with sealing, need to use raw material belt and other sealing materials, for high pressure pipelineCylindrical thread, no taper, more relaxed when rotating, the connection is not sealed, need to use sealing gasket to complete tight, for low pressure pipeline
