What is the difference between NB and PS?
NB is usually written before a piece of important information to make readers notice it. P.S. or PS can be used when you want to add extra information at the end of a letter or email.
What does NB stand for in medical terms?
NASH. Non-alcoholic steatohepatitis. NB. newborn (infant) note well (please pay attention) (from Latin nota bene)
How do I know what type of thread?
- Determine if the thread is straight (parallel) or tapered. The thread is tapered if the diameter increases or decreases.
- Measure the thread diameter.
- Determine the number of threads per inch (TPI) or the pitch (metric threads) with the thread gauge.
- Determine the thread standard.
What does PS mean example?
PS stands for postscript. It comes from the Latin postscriptum, which literally means “written after.” A postscript is an additional thought added to letters (and sometimes other documents) that comes after it has been completed.
How do you identify BSP fittings?
BSPT fittings can be measured instead using the inner diameter. In this instance, a calliper reading can be obtained from inside the fitting bore. The bore size can then be cross-referenced on the chart with the threads per inch and the thread pitch, to determine the standard BSP size and its associated specifications.
What does G thread mean?
BSPP (G) – British Standard Pipe Parallel • BSPT (R/Rp) – British Standard Tapered Pipe, for pipes and tapered thread. An appropriate sealing compound can be used in the thread to ensure a leak-proof joint. BSPP (G) Thread size (inch) Major Diameter (mm)
How do you write NB?
Strictly speaking, the proper way involves underlining the abbreviation, because “nota bene” is Latin. However, most people skip the underlining and just use it like so: You will have 60 minutes to complete the exam. N.B.: Calculators are permitted for use during this exam.
What does NPT stand for?
National Pipe Thread
How do you punctuate NB?
N.B. When the independent clauses are very short, the comma is optional. When the independent clauses are quite long, it might be better to use a semicolon (see below). long, or you want your sentence to sound emphatic rather than flowing.
What does email stand for?
What are different types of threads?
For identification purposes, hydraulic tube fittings and connectors can be divided into six different thread types: UN/UNF, NPT/NPTF, BSPP (BSP, parallel), BSPT (BSP, tapered), metric parallel, and metric tapered.
How do you use NB example?
Also, notice that N.B. is the only Latin abbreviation that should be capitalized. Example: N.B.: While all of the study participants were interviewed about their prior medical histories, researchers did not have access to their medical records to confirm the accuracy of self-reported data.
What uses a 37 degree flare?
Defined by MIL-F-18866 and SAE J514 standards, these flare fittings have been machined to have a 37° flare seating surface. These fittings are most commonly used in fluid power and fuel delivery applications, especially those using high pressure.
ARE AN fittings 37 degree?
AN fittings are a flare fitting, using 37° flared tubing to form a metal-metal seal. They are similar to other 37° flared fittings, such as JIC, which is their industrial variant.
What is a NPT fitting?
NPT (or National Pipe Taper) is a U.S. standard for tapered threads widely used on pipes and fittings for over 100 years. NPT connections rely on thread deformation- a metal to metal sealing design where the threads of the connectors themselves form together.
WHY ARE AN Fittings 37 degrees?
The Joint Industries Council (JIC), sought to clear the air by standardizing the specifications on this type of fitting by creating the “JIC” fitting standard, a 37-degree fitting with a slightly lower class of thread quality than the military AN version. The SAE went on to adopt this JIC standard as well.
What does PS mean in chat?
What is NB mean in email?
What is SAE thread?
SAE stands for the Society of Automotive Engineers. SAE fittings are mostly used in refrigeration, automotive piping systems and other low-pressure applications. It’s common for copper tubes to be used with SAE threads. The SAE male and female halves both have a 45° flare seat.
What is a BSP fitting?
British Standard Pipe (BSP) is a set of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external (male) thread with an internal (female) thread.
What is the difference between R and G thread?
G-threads have a parallel form in accordance with EN-ISO 228-1. R-threads have a tapered form in accordance with EN 10226. In the case of a thread size 1/8”, for example, the threads are specified as G1/8 or R1/8. (BSPT): “R” threads are made pressure tight by using the threads (wedging) to make a pressure tight seal.
Are SAE and NPT the same?
O-Ring Boss: The threads of the SAE straight thread O-Ring Boss (ORB) and the straight thread 37⁰ JIC Flare are the same threads. The difference is the way each thread seals. NPT Pipe Threads: NPT pipe threads are your traditional tapered thread fittings and have been used for 100 years.
Are all NPT threads tapered?
NPT pipe thread is the most common tapered pipe thread used in the United States and Canada and is incompatible with BSPT pipe threads. *This is not NPTF. There are parallel and tapered pipe threads for all pipe standards. NPS, National Pipe Straight, is the American standard for parallel or straight pipe threads.
How is NPT measured?
As a general “rule of thumb” an NPT thread is approximately 1/4″ (0.25”) larger than its “name.” For a 1/4″ NPT fitting the “nominal” OD is 0.533”. NPT fittings are slightly tapered so the “nominal” diameter is the diameter in the middle of the threaded portion, as measured by the top (crest) of the threads.
What are NPT ports?
NPT stands for National Pipe Tapered threads, also known as ANSI/ASME B1. 20.1 pipe threads. It is a U.S. standard for measuring tapered threads on threaded pipes and fittings. Unlike straight threads found on a bolt, a taper thread will pull tight, making a closer seal.
