What is a threaded pipe fitting, and is the pipe fitting thread tapered?

Threaded connection, also known as threaded connection, is to connect pipes and pipes, pipes and valves through internal and external threads. This kind of connection is mainly used for the connection of steel pipes, copper pipes and high pressures, and most of the threads of welded steel pipes are currently operated by threading machines, and for thread processing accuracy and surface roughness.

Demanding high-pressure pipes must be machined with lathes.

1. Iron locks with guarantees, mostly large triangles.

or large D-shaped, for complex connections to equipment, most commonly for protective ropes and harnesses.

links. 2. A connection method in pipeline installation, that is, thread connection.

Also known as threaded connection, it is to connect pipes and pipes, pipes and valves through internal and external threads. This connection is mainly used for the connection between steel pipes, copper pipes and high-pressure pipes, pipe fittings and valves, and most of the threads of welded steel pipes are currently operated by threading machines, and high-pressure pipelines with high requirements for thread processing accuracy and surface roughness must be processed with lathes.

There are two kinds of thread button pipe fittings, one is pipe thread buckle pipe fittings, there are pipe inner wire, pipe outer wire, pipe single wire, pipe thread skin pipe joint, its thickness and length can be customized according to customer needs, and the outer surface is polished; The other is cast wire buckle pipe fittings, commonly known as albino pipe fittings, with internal thread elbow, hexagonal outer wire, hexagonal leather pipe joint, internal thread tee, internal thread union, internal thread plug, threaded cap, core filling, reducing tee, reducer head and other various connection methods are threaded connections.

Threaded pipe fittings are threaded pipe fittings, and the connection methods of pipe fittings are welded, socketed, and threaded.

There are two kinds of threaded pipe fittings, one inner wire and one outer wire, and the thread refers to the threaded connection place!

Not tapered.

Threaded connection, also known as threaded connection, is to connect pipes and pipes, pipes and valves through internal and external threads.

In a way, the thread buckle is our common screw nut.

The part of Qingrui company's buckle wire that is most prone to rust is still the thinnest part of the zinc layer, so it is necessary to test whether the thinnest part meets the standard.

Copper sulfate is generally used as a homogeneity test, but this method is problematic for testing zinc coating films composed of zinc and alloy layers. This is due to the difference in the dissolution rate of the zinc layer and the alloy layer in the copper sulfate test solution, and the difference in the ratio of zinc to iron in the alloy layer. Therefore, it is not very reasonable to judge uniformity by the number of repetitions of a certain impregnation time.

As a result, there has been a tendency to abolish this test method in recent European and American standards and JIS standards, and to replace uniformity with distribution, focusing on visual or tactile sensations, and using a film thickness gauge to check the distribution status only if necessary.

It is not easy to measure the area of small components with complex shapes, and it is not easy to obtain the average film thickness, so sometimes the copper sulfate test method has to be used as a reference, but the copper sulfate test must not replace the purpose of adhesion measurement Professional manufacturer Qingrui company.

Threaded valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid gold and radioactive media.
