Storz Coupling

Storz coupling

The Storz coupling is a type of standardized fittings connecting fire hoses, especially large diameter ones, to fire hydrants, pumps, and the inlets so that water can be supplied to fire sprinklers or standpipe systems.

How are Storz couplings measured?

Storz couplings are easily identifiable by the lug distance. To find out the lug distance of a coupling, measure the inside distance between the lugs with a pair of calipers.

What is Storz Adaptor?

Storz fittings adapter are a type of fire adapter that is used to connect two pieces of equipment together.

What is Storz hydrant?

Storz is a type of hose coupling invented by Carl August Guido Storz in 1882 and patented in Switzerland in 1890, and patented in the U.S. in 1893 that connects using interlocking hooks and flanges. It was first specified in standard FEN 301-316, and has been used by German fire brigades since 1933.

What does Storz mean in German?

German: from the dialect word storz 'stalk stump' presumably a nickname for a short person. Source: Dictionary of American Family Names ©2013, Oxford University Press. Similar surnames: Stotz, Storr, Stolz, Stortz, Stork, Storm, Stock, Stark, Storer, Star.

What is a MacDonald coupling?

MacDonald quick action couplings are designed for high pressure compressed air or inert gas. They are widely used in oil refineries, in chemical plants for nitrogen service and in general engineering industry. They are also used with pneumatic tools and for fire hose reel service where safety is a prime concern.

What is lug size in fire hose coupling?

Lug Size : 72 mm.

What is lug size of hydrant?

Diameter: 50/65. Inlet: 100mm. 2*DN65 internal lug pin coupling.

What is NST pipe thread?

NH stands for National Hose and NST stands for National Standard Thread. This is often referred to as “fire hose thread” because fire departments use it the most. It's popular on many fire hydrants and accessories.

How do you pronounce Storz?

Karl starts SC. And company kg Karl starts SC and company kg Karl starts SC and company kg Karl

What is fire hose coupling?

Hose couplings are used to connect one hose to another and increase overall length of a fire hose. They are attached to each end of a length of fire hose. Hose couplings are also used to connect hose to appliances like hydrants, wyes, and Siamese connections.

What thread is fire hydrant?

A standard fire hydrant has two 2.5 inch- hose connection nozzles with 7.5 threads per inch, and one 4.5 inch-pumper connection nozzle with 4 threads per inch.

What are two types of hydrant connections?

For most intents and purposes, there are two types, wet and dry barrel hydrants, in addition to standpipes. These have a different structure and mechanism depending on the surrounding conditions.

What is hose thread called?

The standard thread used for garden hoses is commonly known as garden hose thread (GHT), but officially its title is NH ("National Hose") defined in ANSI B1.

How do two way couplings function?

In a two-way coupling, fluid flow is affected by structural deformation and at the same time structural deformation is affected by fluid flow. Wind power point is an example of a two-way coupling. Here, converged solutions of the fluid flow influence the solid body deformation when the first time step runs.

What is the function of hose couplings?

A hose coupling is a type of fitting located on the end of the fire hose, which is typically made of steel, brass, or aluminum. The coupling has threading on each end, one female end and one male end, allowing the hose to connect with another hose, tap, or other water source.

Which type of valve is typically used on engine discharges?

Ball valves – used in pumper discharges and gated wyes. Gate valves – used to control the flow from a hydrant. Butterfly valves – used on large pump intakes.

Is NST same as NPT?

NST also goes by the initials NH or National Hose. It can even be referred to as NHT or National Hose Thread but NST or NH is more common these days. NH = NST. Fire hoses with National Pipe Straight Hose Thread (NPSH) have the same threads per inch as National Pipe Thread (NPT), but the threads do not taper.

Is NH thread same as NST?

NH / NST Threads It is often referred to as “fire hose thread”. NH, NST and NHT are different abbreviations for the exact same thread. The female and male side of a fire hose coupling with NH threads will only connect to fittings, nozzles or hoses with the same threads.

What is NPT vs MIP?

As previously mentioned, NPT indicates the defined standard from ANSI - but many people use MPT/MIP and FPT/FIP interchangeably. MPT stands for Male Pipe Thread and MIP stands for Male Iron Pipe which both indicate a male fitting with NPT threads.
