Are there metric pipe fittings?
Metric Push-In Universal Threads The unique feature with these fittings is their ability to use the same fittings for NPT, BSPT or BSPP threads. These fittings also are available for fractional and metric tubing. The universal threads will seal on inclined, concave and convex surfaces.
Does NPT fit FIP?
FIP Female Iron Pipe (interchangeable with NPT) FIP, Female Iron Pipe, or Female International Pipe- Similar to FPT, FIP connect NPT pipe together with internal threads. MPT the threads are located on the outside of the pipe or fitting.
Is NPT same as MIP?
Yes, NPT (national pipe thread) has the same thread dimensions as an MIP (male iron pipe) and FIP (female iron pipe).

What is a #30 drill bit?
We start by displaying drill bit Number 30 in decimal inches as follows: #30 drill bit = 0.1285 inches. 0.1285 decimal as a fraction is 257/2000. However, standard fractional drill bits come in intervals of 1/64 inches.
What are the standard drill sizes?
Range 1 (R1) is shortest in length, more common for sizing production tubing or casing, and ranges from 18 to 22 ft. Range 2 (R2) is considered the standard length for drill pipe and ranges from 27 to 31 ft. Range 3 (R3) is common in casing and also deployed in deep water drilling applications.
What size drill do you use for tap?
Drill Bits and reamers. The two most common methods of creating starter holes for taps are drilling with just a drill bit or drilling with both a bit and reamer.
How is NPT measured?
NPT is defined by ANSI/ASME standard B1.20.1. The taper rate for all NPT threads is 1 inch of diameter in 16 inches of length (3⁄4 inch per foot or 62.5 millimeters per meter) measured by the change of diameter (of the pipe thread) over distance of thread.
What size drill bit for a pipe tap?
Most drill charts recommend a 5/16 drill for a 3/8-16 bolt. Cutting holes that are smaller will leave more material for the tap to cut out, risking tap breakage. Drilling larger holes will result in weaker threads, increasing the possibility of stripping them.
