Grooved Pipe Couplings and Fittings —— 11.25° Elbow

Convenient connection: 

adopting groove connection, no need for welding or threaded connection, when installing, just insert both ends of the pipe into the groove of the elbow, and then fix it with the clamp, easy to operate, which can effectively shorten the construction time.

Good sealing performance: 

Equipped with a sealing rubber ring, it can form a good seal at the pipe connection, prevent fluid leakage and ensure the sealing and stability of the piping system.

Flexible angle: 

11.25° bending angle, compared with the common 90° elbow, 45° elbow, can provide more flexible pipeline steering options, can be used in some need to precisely adjust the pipeline direction of the occasion, so that the piping system layout is more reasonable.

Variety of materials: 

usually made of ductile iron, carbon steel, stainless steel and other materials, with good strength, corrosion resistance and abrasion resistance, can adapt to different working environments and media requirements, such as fire protection systems, water supply and drainage systems, HVAC systems, and so on.

High pressure level: 

generally have a high pressure tolerance to meet the different pressure requirements of the pipeline system, the common pressure level of 300Psi, 500Psi and so on.

Application areas

Fire-fighting system: 

It is widely used in fire sprinkler system and fire hydrant system, which facilitates the laying and steering of pipelines to ensure that the fire-fighting water flow can reach each water spraying point or fire hydrant smoothly and carry out the fire-fighting work quickly and effectively.

Water Supply and Drainage System: 

It is used in the living water supply and drainage pipeline system in buildings, as well as municipal water supply and drainage pipeline projects to realize the connection and steering of pipelines, and to ensure the normal delivery and discharge of water.

HVAC system: 

in the air conditioning chilled water, cooling water piping system, as well as ventilation piping system, it can be used to adjust the direction of the pipeline, so that the air or water flow can be circulated in the system according to the design requirements, to achieve the purpose of regulating the indoor temperature, humidity and air quality.

Industrial piping system: 

In the piping system of chemical industry, petroleum, electric power, metallurgy and other industrial fields, it can be used to connect the pipelines of different directions to convey various industrial media, such as corrosive liquids, high temperature steam, gas and so on, to satisfy the technological requirements in the industrial production process.

Installation Precautions

Pipe cutting: 

use specialized cutting tools to ensure that the pipe cut is smooth and burr-free to ensure that the groove of the pipe and elbow can be closely matched.

Pipe end treatment: 

clean and polish the end of the pipe to remove oil, rust and other impurities, and at the same time check whether the end of the pipe is deformed or damaged, if there is any problem, it is necessary to repair or replace the pipe in time.

Installation of sealing ring: 

Place the sealing ring correctly in the groove of the elbow, make sure that the sealing ring is not twisted, deformed or damaged, and then apply appropriate amount of lubricant on the sealing ring to facilitate the insertion of the pipe.

Clamp Installation: 

Place the clamp over the connection between the pipe and the elbow to ensure that the clamp is correctly positioned, and then tighten the bolts on the clamp evenly to secure the clamp tightly to the pipe, but be careful not to over-tighten the bolts to avoid damaging the clamp or the pipe.
