Pipe Fittings/Tube Connectors


Pipe Fittings/Tube Connectors are connecting tool between pipes and pipes, and a detachable connection point between components and pipes. It plays an indispensable role in pipe fittings, and it is one of the two main components of hydraulic pipelines.

Pipe Fittings/Tube Connectors

Pipe joints are used for straight line connections such as instruments, and the connection forms include socket welding or threaded connections. It is mainly used for small-diameter low-pressure pipelines, for parts that need to be assembled and disassembled frequently, or as the final adjustment of pipelines using threaded pipe fittings.


Different Types of Pipe Tube Fittings/Connectors


Pipe Fittings/Tube Connectors are a general term for the components in the pipeline system that play the roles of connection, control, direction change, flow splitting, sealing, and support. Pipe fittings include a wide range of common flanges, unions, pipe clamps, ferrules, throat clamps, tee and so on. What is the main purpose of these pipe fittings? How to classify it?

• Pipe clamp: a pipe fitting used for pipe fixing, a type of pipe fitting commonly used in plumbing installations, used to fix pipes.


• Valve: a control component in a fluid conveying system, with functions such as cut-off, regulation, diversion, pressure stabilization, diversion or overflow and pressure relief.


• Compensator: It is composed of bellows and end pipes, brackets, flanges, conduits and other accessories of the main body of its work. It belongs to a kind of compensation element.


• Decontamination device: prevent impurities in the pipeline medium from entering the transmission equipment or precision parts, causing production failure or affecting product quality.


• Reinforcing tube: Reinforcing means increasing strength. Improve the strength of the area by increasing the stressed area, basically a forged tube.


• Snap ring: It is the main retainer for removable denture restoration. It is made of metal and mainly plays the role of retention, stability and support.


• Tow hook: refers to the hook on the tugboat for hooking the tow line and making it easy to release. It can be divided into spring tow hook, hydraulic tow hook, remote control tow hook, etc.


• Lifting ring: It is a kind of industrial spreader, a device for lifting heavy objects in hoisting machinery. Common lifting rings include round lifting ring, pear-shaped ring and so on.


• Bracket: The truss supporting the middle roof truss is called a bracket, generally a parallel chord truss, and its web member adopts a herringbone system with vertical rods.



By connection - Tube Connector/Pipe Fittings


• Welded pipe fittings: pipe fittings connected to pipes by welding, including elbows, flanges, tees, reducers, heads, etc.

Welded Pipe Fittings

• Threaded fittings: threaded fittings, commonly used in water and gas pipes, small-diameter water pipes, compressed air pipes and low-pressure steam pipes.


• Tube fittings: It is a new type of quick fittings with good sealing performance and can be used repeatedly. It is suitable for pipeline systems of oil, gas and general corrosive media.


• Clamp pipe fittings: used to fasten the connection between quick joints, including clamps, quick joints, silicone sealing gaskets, chuck blinds, etc.


• Undertaking pipe fittings: a kind of high-pressure pipe connection fittings that are formed from round steel or steel ingot die-forged blanks, and are machined and formed by lathes.


• Curved double-melt fittings: Fittings with ports of the same size as the pipes to be connected, and connected by hot-melt butt welding.


• Bonded pipe fittings: pipe fittings that are connected by solvent-based adhesives, such as PVC plastic pipes.


• Rubber ring-connected pipe fitting: It is composed of pipe fitting body, sealing end cover and sealing rubber ring.


By material - Tube Connector/Pipe Fittings


• Cast steel pipe fittings: The design thickness of cast steel pipe is large and heavy, its weldability is poor, and its carbon content is high, so the welding seam requires on-site heat treatment.

Pipe Fittings Stainless Steel

How to Indicate the Model of The Pipe Fittings


The types of pipe fittingss include straight-through fittingss, straight-through fittingss, tee fittingss, elbows, fittingss with living nuts, hinged fittingss, plugs, transition fittingss, etc. The composition of the double ferrule fittings is a front snap ring, a rear snap ring and a nut. Commonly used materials are stainless steel and carbon steel metric, American and British thread standards.


NPT, PT, and G are all pipe threads. NPT belongs to the American standard 60-degree tapered pipe thread, which is used in North America. It is a 55-degree sealing tapered pipe thread. It belongs to the Whitworth thread family and is mostly used in Europe and the Commonwealth of Nations. Commonly used in the water and gas pipe industry, the taper is specified as 1 to 16.


G is a 55 degree non-threaded sealing pipe thread, which belongs to the Wyeth thread family, and is marked with G for cylindrical thread. The quarter, half, and eighth marks in the thread refer to the diameter of the thread size, in inches. People in the industry usually use minutes to refer to the thread size. One inch is equal to 8 minutes, and one quarter of an inch It is 2 points, and so on. G is the general name for pipe threads (Guan), and the division of 55 and 60 degrees is functional, commonly known as pipe circle. That is, the thread is machined from a cylindrical surface.


ZG is commonly known as pipe cone, that is, the thread is processed by a conical surface. The old domestic thread is marked as Rc and the external thread is R. The metric thread is expressed by the pitch, and the American and British threads are expressed by the number of threads per inch. This is The biggest difference between them is that the metric thread is a 60-degree equilateral thread, the inch thread is an isosceles 55-degree thread, and the American thread is 60 degrees. Metric threads are in metric units, and American and British threads are in imperial units.


Pipe threads are mainly used to connect pipes, and the inner and outer threads are closely matched, and there are two types of straight pipes and tapered pipes. Nominal diameter refers to the diameter of the connected pipe, obviously the major diameter of the thread is larger than the nominal diameter. One-quarter, one-half, and one-eighth are the nominal diameters of imperial threads in inches.
