常见问题

What is the difference between NPT and BSP thread fittings?

NPT (National Pipe Thread) has a 60° thread angle and tapered design for sealing through thread interference. BSP (British Standard Pipe) has a 55° thread angle and can be parallel (BSPP) or tapered (BSPT). They are not interchangeable without adapters.

How do I select the right material for process connection fittings?

Consider: 1) Fluid compatibility (chemical resistance), 2) Operating temperature range, 3) Pressure requirements, 4) Corrosion environment, 5) Regulatory requirements (FDA, USP Class VI for food/pharma). Stainless steel 316L is common for corrosive applications.

What maintenance is required for process connection fittings?

Regular inspection for leaks, thread damage, or corrosion. Periodic torque checks on threaded connections. Replacement of gaskets/O-rings during sensor recalibration. Cleaning of sealing surfaces before reassembly.
