As with NPT threads, the nominal size does not represent true outside pipe diameter but in the larger sizes it comes very close. Sizes start at 1/16˝ and go up through 6 inches. Note: there is no ISO thread modification such as the NPTF (National Pipe Thread Fuel) for improved sealing between threads. Usually a thread sealant is required.

For industrial sewing threads it is important to understand the following terms: Tex - Weight in grams of 1,000 m of thread.Denier - Weight in grams of 9,000 m of thread.Cotton Count (NeC) - Weight in pounds of 840 yards. Industrial thread sizes are usually expressed by Tex size or Ticket number. When only the total Denier is known, to.

For example, 8/16" or 1/2" equates to size -8 . Note: dash numbers are nominal. Since metric measurements give the true sizes of a tube or a fluid pipe, dash numbers do not apply for them. For example, for M12x1.0, the outer diameter of the threads is 12 mm with a 1.0 mm spacing between threads, Hydraulics Direct Reviews

The metric thread sizes are generally expressed as M2 × 0.25, the thread diameter is 2mm and pitch is 0.25mm. Thread Dimensions - Imperial Thread Sizes Chart

This can be determined whether by visual inspection or by measuring the diameter of the thread at the beginning and the end via a caliper. Thread Diameter: For male threads, measure the major diameter and for threads measure the minor diameter. Note that this diameter will always be different from the nominal size of the thread.

Minimum = 0.033P for all pitches. See table for maximum. When using L1 gauges to check threads, the thread is within permissible tolerance if the ring gauge face, or plug gauge notch, is +/- 1 turn from being flush with the end of the thread. Example designation: 3/8 - 18 NPT. where: 3/8 = nominal pipe size. 18 = number of threads per inch.

Each thread in the series is characterized by its major diameter D maj and its pitch, P.UTS threads consist of a symmetric V-shaped thread. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. The outermost 1 ⁄ 8 and the innermost 1 ⁄ 4 of the height H of the V-shape are cut off from the profile.. The pitch P is the distance between thread peaks.

Sealing is provided by a pre-coating on the thread. Thread designation • BSP Parallel (BSPP): G followed by the denomination, according to standard ISO 228-1. Example: 1/8 BSP parallel thread = G1/8 • BSP Taper (BSPT): R followed by the denomination, according to standard ISO 7-1. Example: 1/8 BSP taper (BSPP) thread = R1/8 • threads:

There are two types of BSP Thread available. One is Parallel threads or we can say Straight threads. The second one is the Taper Thread. BSP is BRITISH STANDARD PIPE THREAD- Also known as Whitworth 55° Thread Form. BSPT is BRITISH STANDARD PIPE TAPER THREAD - Thread form per AS 1722.1, BS 21, ISO 7.

NPT/NPS threads have a 60° angle and have flattened peaks and valleys (Sellers thread form) where as BSP threads have a 55° angle and have rounded peaks and valleys (Whitworth thread form). NPT and BSP thread pitches (threads per inch) are listed below. To determine pitch, use a thread gauge or count the number of threads that fall into a 1

Thread size refers to the nominal bore of the pipe. Subtract approx. 1/4″ (6mm) from thread diameter measurement for nominal pipe size. Pitch is Threads Per Inch (TPI). "Gas", "R" & "G" also refer to BSP. "Male Iron (Pipe)" may be BSP or NPT. NPT & NPS Threads NPT is NATIONAL PIPE TAPER (AMERICAN): Thread form per ANSI/ASME B1.20.1

At least 41 thread sizes have been defined, ranging from 1 ⁄ 16 to 18, although of these only 15 are included in ISO 7 and 24 in ISO 228.

UNC - 60 Degree Unified Coarse Threads. UNC Thread Series / UNRC are the one most commonly used in the bulk production of bolts, screws, nuts and other general engineering applications. It is also used for threading into lower tensile strength materials such as cast iron, mild steel and softer materials (bronze, brass, aluminum, magnesium and
