Pipe fittings are used to connect pipes, to change flowing direction, or to change the pipe diameter. According to the shapes and uses, pipe fittings include elbows( 45 degrees or 90 degrees), tees, crosses, unions, end caps, and couplings.
Pipe fittings have many different series to accommodate different applications and requirements.Here are some common series which FLUIDO can supply:
A) Butt weld pipe fittings: These fittings are used for welding pipes together. The common materials are carbon steel or stainless steel. Because the weld connection is strong and leak-proof, so butt weld steel pipe fittings can be used in various industrial applications, especially for high-pressure and high-temperature scenes.
B) Forged steel pipe fittings: These fittings are made by heating and hamming a piece of steel. This production process makes the fittings more durable and stronger than casting ones. They usually have a thicker wall thickness and can bear higher pressure and higher temperatures than other types of pipe fittings. Because the costs are higher, forged pipe fittings are only used in high-pressure or high-temperature pipe systems. And not be used for big-size pipelines. The sizes are usually from 1/4” to 6”. According to the material, there are carbon steel forged pipe fittings and stainless steel forged pipe fittings.
C) 150 lb stainless steel pipe fittings: These stainless steel pipe fittings are threaded fittings. They connect with pipes by threads without welding. These fittings can be used in pipe systems like plumbing systems where the pressure is under 150lb, and which need corrosion resistance.
D) Malleable iron pipe fittings: These fittings are made from a type of cast iron malleable iron, which can be easily shaped and formed. They are commonly used in plumbing systems and other applications where strength and durability are required. Similar with 150lb stainless steel screwed pipe fittings, malleable iron pipe fittings also come with threads for easy installation. We didn’t show malleable iron pipe fittings on our website, but these are also our main products.
E) Ductile iron pipe fittings are made from ductile iron by casting. Ductile iron has a microstructure which makes it more durable, strong, and flexible. Ductile iron fittings can be used in oil, water, and gas systems, etc.,
The flange has a center hole and some bolt holes around it. They are usually used to connect pipes with pipes or with valves or other equipment. Normally one end is welded or threaded to pipes and another end connects the equipment with bolts. Size usually from 1”-24”. Qingdao Fluido is a manufacturer of different types of flanges and has big advantages in prices. We have a mature quality control system, which can ensure stable quality.
According to connection types, there are weld neck type, slip-on type, socket weld type, threaded type, lap joint type, blind type, backing flange, and spectacle blind flange etc.,
1. Weld Neck Flange: This type of flange has a neck for welding to pipes. It can bear high pressure and has good performance of leak-proof. It is widely used in various applications.
2. Slip-On Flange: This flange slides over the end of a pipe or fitting and is then welded in place. It is easier to align and install compared to a weld neck flange. However, the pressure bearing capacity is not as good as the weld neck flange.
3. Socket Weld Flange: This type of flange has a socket end, insert the pipe end on the socket end and weld the pipe with the top of the flange. This type of flange is usually used for small-sized pipes with high pressure.
4. Threaded Flange: These flanges have threads that allow them to be screwed onto a pipe or fitting. They are commonly used in low-pressure applications.
5. Lap Joint Flange: This type of flange has two parts, a stub end fitting and a backing flange.The flange slides on the stub end and welds the stub end to the pipe end. This allows the flange can be moved on the pipes. It is often used in applications where frequent dismantling is required.
6. Blind Flange: This flange doesn’t have a center bore, it is used to block off a pipe.
7. Spectacle Blind Flange: This type of flange is like a number 8, it has two pieces of flanges, one is blind and another one has a bore, the two are connected together with a metal band. It is normally cut from one piece of metal plate. It can be rotated to block or allow flow through the pipe for easy maintenance.
Valves are used to control the flow in pipe systems. Some can stop the flow or let it go like a gate valve, or butterfly valve, some can control the flow rate like a ball valve, some can keep the medium flow in one direction like a check valve or globe valve, and some can control the pressure in a system like pressure release valve. The different valves are used in different applications based on the different requirements and environments. Qingdao Fluido has a factory that can supply cast iron valves and cast steel valves of different types. Please visit FLUIDO VALVES to understand more about our valve products.
Pipe nipples and couplings are used to connect two pipes together. They are made from pipes, cut pipes to short sizes, and make threads on one end or both ends according to different requirements. The short pipes with male threads are called pipe nipples, with female threads called couplings. Pipe nipples and couplings also different types, like hose nipples, hex nipples, barrel nipples, close nipples, full couplings, half couplings and reducing couplings, etc., Qingdao Fluido can manufacture different types of pipe nipples and couplings.
Pipe hangers are used to support and secure pipes to walls, ceilings, or other structures. They come in various designs, including adjustable clevis hangers, swivel ring hangers, split ring hangers, etc., Pipe clamps can connect pipes or other equipment without welding or threading. Pipe clamps usually come with steel shells and rubber seals. Pipe clamps have many different types, hose clamps, heavy type clamps, pipe repair clamps, no-hub pipe clamps, and u-bolt pipe clamps etc., We can supply various of pipe clamps, welcome to contact us if you need any pipe clamps.
1. What are pipe fittings?
Pipe fittings are components used to connect, control, and redirect the flow of liquid or gas through a piping system. They come in various shapes, sizes, and materials to accommodate different types of pipes and applications.
2. What are the different types of pipe fittings?
There are several types of pipe fittings, including elbows, tees, reducers, couplings, unions, and adapters. Each type serves a specific purpose in a piping system, such as changing the direction of flow, connecting two pipes of different sizes, or joining pipes together.
3. What materials are pipe fittings made of?
Pipe fittings are commonly made of metal, such as stainless steel, carbon steel, brass, or copper. They can also be made of plastic, PVC, or other materials depending on the application and the type of pipe being used.
4. How do I choose the right pipe fitting for my application?
When selecting a pipe fitting, consider factors such as the type of pipe being used, the size and pressure rating of the piping system, the temperature and chemical compatibility of the materials being transported, and the required flow rate and direction.
