What is DN in size?

DN stands for diametre nominal, which denotes the size of a pipe (specifically, its inside diameter) in millimeters (mm). NPS, or nominal pipe size, is merely the non-metric equivalent in which the diameter is measured in inches (in.).

What is DN150 pipe?

Diameter of suitable steel welding pipes. 168.3 mm (DN150)

What does dn100 stand for?

DN stands for 'Diameter Nominal'. Put simply, it is a rough translation of mm from imperial sizes, assuming that an inch is 25mm. We refer to a 12″ flange as DN300, when in fact it is 304mm.

What does dn15 mean?

Diameter Nominal DN (mm)	Nominal Pipe Size NPS (inches)	Outside diameter (OD) inches (mm)
10	3/8	0.675 in (17.15 mm)
15	1/2	0.840 in (21.34 mm)
20	3/4	1.050 in (26.67 mm)
25	1	1.315 in (33.40 mm)

What does DN and PN mean?

Nominal diameter (DN) and nominal pressure (PN)

What does PN16 mean?

'PN' stands for Pressure Nominale and prefixes the pressure rating, e.g. a PN16 flange is designed to operate up to 16 bar. Typical ratings include PN6, PN10, PN16, PN25, PN40, PN64, PN100. The American ANSI standard refers instead to a pressure / temperature rating termed 'Class'. 4.

What is PN16 pipe?

The acronym PN stands for Pressure Nominal. When a pipe has a rating of PN16, it is designed to handle 16 Bar internal pressure. Poly pipe comes in a range of pressure ratings: PN10 which has a maximum pressure rating of 1000kpa.

What is a DN number?

DN Factor, also called DN Value, is a number that is used to determine the correct base oil viscosity for the lubrication of various types of bearings. It can also be used to determine if a bearing is the correct choice for use in a given application. It is a product of bearing diameter (D) and speed (N).

What is 150 NB pipe size?

Nominal Bore (metric / NB / DN)	Nominal Bore (Imperial)	Pipe Outside Diameter (metric)
80 mm	3 "	88.9 mm
100	4 "	114.3 mm
125	5 "	139.7 mm
150	6"	168.3 mm

What does dn50 mean?

For reference, a DN 50 pipe indicates a pipe with an external diameter of 60.3 mm and a wall thickness of 3.65 mm according to EN 10255 (resulting indoor diameter of 53 mm).

Is DN and NB the same?

It is worth remembering also that nominal bore can have different names. In the inch system, nominal bore is abbreviated as NB; in metric systems, it is “diameter nominal” (DN), or Nominal Pipe Size (NPS) in North America.

What is DN in HDPE pipe?

Where dn is the nominal outside diameter of pipe and en is the nominal (minimum) wall thickness of the pipe.

What is PN 10 in valve?

PN10, PN16, PN25 and PN40 specify both pressure class in bars of pressure, and metric flange dimensions (such as bolt circle diameter, hole size, bolt size etc) according to international flange standards such as ISO 7005-1 or DIN 2501 that use the metric system of measurements.

Are PN10 and PN16 the same?

Once you have your PCD measurement, look it up in the tables below to determine the drilling standard. Note: PN10/16 - Some flanges are denoted PN10/16. These refer to the fact that either PN10 or PN16 flanges will fit, as the drillings for many sizes are the same.

What is a DN15 thread?

The DN = Diameter Nominal not Imperial nor US standard. E.g. the DN15 is for the pipe 21.3mm, wall 2.65 making inside diameter 16mm. The NPS 1/2 might be equal DN15.

What is DN 40 valve?

This valve is rated for 6 bar and is operated by hand, but can be used with an actuator (ISO 5211 F05). The nominal diameter is 40 mm (1-1/2 inch) and has a lug type flange. The Cast iron (GGG40) housing, stainless steel disc and FKM seal make it durable and allows for a media temperature between 5°C and 180°C.

What does PN 20 mean?

Similarly, PN 20 pipe means the pipe is designed to withstand a pressure of 20 bar at the maximum design temperature. For PE/HDPE pipes the PN rating pressure usually denotes the pressure capability at a temperature of 20°C.

What is class 150 flange pressure rating?

For example, a Class 150 flange is rated to approximately 270 PSIG at ambient conditions, 180 PSIG at approximately 400°F, 150 PSIG at approximately 600°F, and 75 PSIG at approximately 800°F. In other words, when the pressure goes down, the temperature goes up and vice versa.
