productcate-1-1

High strength

Grooved Iron Pipe Fittings are made of ductile iron material and undergoes various heat treatments to increase hardness, they have high strength, toughness and wear resistance. These fittings are not easy to bend or break during use, and can withstand the internal and external pressure of the pipeline system, to be long-term used.

Corrosion resistant

The surface of these fittings is available in a variety of coating materials, including ceramic coating, epoxy resin coating and polyurethane coating. These coatings can not only increase their wear resistance, but can also be evenly covered on their cast iron base to isolate the air, protecting them from corrosion by salt water, steam and chemicals.

The main components of a grooved fitting system

Grooved Coupling

Its surface is designed with grooves through which pipes, Its surface is designed with grooves through which pipes, fittings and valves can be held together. It is used to connect wet and dry systems and can easily connect and disconnect two pipes.

Grooved Flanges

It is used to connect grooved pipes to flanged pipes and has a groove on one end for easy connection with any grooved joint.

Gasket

It is made of materials such as rubber, EPDM or nitrile rubber and is used to seal the connection between two grooved couplings.

Pipe End

It is used to cover the ends of grooved pipes and is made of metal or plastic.

Valve

It is used to control fluid flow in grooved pipes and comes in different types such as ball valves, butterfly valves and gate valves.

Fitting

It is used to change the direction or angle of grooved pipes, or to connect two or more pipes. There are many types such as elbows, tees and reducers.

Hanger and Support

They are used to support grooved pipes to prevent them from sagging or moving and come in different structures such as clamps, brackets and rollers.

 

Product Application 

 

right-1.png

Jianzhi fittings are used in all kinds of pipeline systems of transporting water, oil, air, gas, among other fluids. These fittings have the advantages of simple installation, reliability and low maintenance, and are often used in water supply, fire protection, HVAC and mining and other fields. . They provide leak-free connections between pipes and valves, pumps and flanges, ensuring efficient use of pipes.

FAQ

 

Q: What is grooved pipe fittings used for?

A: Grooved fittings are used to connect pipes or shafts, such as commercial HVAC and fire protection systems, with quick installation and easy maintenance. They are made from materials such as ductile iron, stainless steel, copper and PVC and are available in a variety of sizes and configurations to fit a variety of pipes.

Q: Can you groove cast iron pipe?

A: Yes, you can do this. The grooves of ductile iron pipes are machined at the ends of the two pipes, which generally has a larger radius to provide stronger load capacity.

Q: How is grooved piping joined together?

A: Grooved pipings are joined together by grooved mechanical joints mounted on the end of the pipe. These couplings have internal grooves that match the external grooves on the pipe, can create a tight seal when the clamp is tightened.

Q: What is one of the most common uses for grooved pipe fittings and couplings?

A: It is to connect and secure pipes in various industrial applications, including HVAC, fire protection systems, pipelines, and water treatment systems, for withstanding high pressure and vibration.

Q: What are the different types of fittings in fire fighting pipeline?

A: There are several different types of fittings that can be used in a fire fighting pipeline, including Couplings, Elbows, Tees, Reducers, Valves, Flanges and Caps.

Q: What is a mechanical joint for ductile iron pipe?

A: It is the most common joint for connecting PVC pipes to valves or iron fittings and is made of graphite cast iron material with a bell, gland, rubber gasket, and bolts and nuts. When it is used, a bell jar is often used to compress the gland so that the gasket is embedded to achieve a high degree of sealing during pipe connection.

Q: What is the purpose of a pipe floor flange?

A: These flanges are used to mount cast iron malleable pipe to floors or walls. Most of their models are 7-8.5m in diameter and are welded or threaded onto the end of the pipe to allow objects to be attached to it, ideal for tight spaces.

Q: What is grooved flange adapter?

A: It consists of two flanges and a middle arc-shaped groove part, which is used to connect between two pipes of different diameters or different materials, and ensures a tight and secure connection.

Q: What is a split flange used for?

A: Split flanges consist of two interlocking pieces and are available in conventional sizes ranging from 1 ½ inches to 4 inches. They are securely mounted to the piping system with nuts and bolts or welding to reinforce weak areas of high-pressure piping and create an even seal.

Q: What is mechanical tee with grooved branch?

A: As part of a trenched duct system, they provide direct branch connections on the pipe. Before use, they are pre-cut with holes in the pipe that match the size of their branch structure, and are connected to the pipe with fixed gaskets to ensure a high degree of sealing.

Q: What is the difference between mechanical tee and grooved tee?

A: Mechanical tee connects pipes by using a bolted joint, whereas a grooved tee connects pipes by using a grooved mechanical coupling. The former is suitable for pipes with high pressure, high temperature and high viscosity fluids. While the latter is suitable for low pressure, high speed and large flow scenarios.

Q: Which is better concentric or eccentric reducer?

A: It depends on the particular application and requirements. Concentric reducers are ideal for pipelines that require a gradual reduction in pipe diameter, where the centerline of the pipeline remains in the same axis. They are commonly used in vertical pipelines to ensure that the fluid flow remains centered and does not cause turbulence. Ccentric reducers are ideal for pipelines that require a larger reduction in pipe diameter, commonly used in horizontal pipelines to prevent the accumulation of air or fluids at the low point of the pipeline.
