Dismantling Joint,
Flange Adaptor,
Duckbill Check Valve and other accessories work together to build a flexible and efficient pipe steering network.
Core function: "Direction to Commander" with right-angle steering
The core value of the 90-degree elbow lies in precisely changing the flow direction of the pipeline. Its unique right-angle design enables the fluid to achieve a 90-degree turn in the pipeline, reducing resistance loss. This turning function complements the Flexible bending characteristics of the Flexible Metal Hose - the former realizes a fixed-angle turn, while the latter ADAPTS to any Angle offset. At the connection between the vertical pipe and the horizontal pipe of the building water supply and drainage system, the 90-degree elbow connects pipes of different directions through the Flange Adaptor, and is combined with the Rubber Expansion Joint to absorb the impact and vibration of water flow, ensuring smooth drainage without retention. Its turning accuracy far exceeds that of ordinary Pipe Fittings .
In the complex layout of industrial pipelines, the turning function of 90-degree elbows is even more crucial. The acid and alkali pipelines in the chemical workshop achieve a circuitous direction through multiple 90-degree elbows, cooperate with the Bellow Expansion Joint to compensate for the thermal displacement of the pipelines, and the Duckbill Check Valve to prevent the backflow of the medium. The three work together to ensure that the corrosive medium has no leakage during the turning process. Its steering stability directly affects production safety.
Material Diversity: A "Material Think Tank" Adapted to Working Conditions
The material options for 90-degree elbows are rich and diverse, which can precisely match the requirements of different working conditions. Stainless steel elbows, with their high strength and corrosion resistance, have become the preferred choice in industries such as chemical engineering, petroleum, and natural gas. In offshore oil pipelines, stainless steel 90-degree elbows, when used in conjunction with Flange adaptors, can resist seawater corrosion and high-pressure impact. It forms a "double corrosion barrier" with the corrosion-resistant metal material of Bellow Expansion Joint, significantly extending the service life of the pipeline system.
Cast iron elbows are suitable for low-pressure pipeline scenarios. In the buried pipelines of municipal water supply, their rigid structure is used in conjunction with Dismantling Joint, which is convenient for later maintenance and replacement. Rubber Expansion Joint is installed at the outlet of pumps and valves to absorb vibration. The two work together with cast iron elbows to ensure the stability of the water supply system. Alloy steel elbows play an advantage in high-temperature and high-pressure pipelines. At the turning point of steam pipelines in thermal power plants, alloy elbows cooperate with
Bellow Expansion Joints to withstand the impact of high-temperature steam, and Flange adaptors ensure the connection seal. The pressure resistance performance at the turning point is not reduced in the slightest.
Plastic materials such as PVC, PPH, PVDF and FRPP elbows dominate the civil and light industrial fields with their lightweight, corrosion-resistant and easy-to-install features. In the building stormwater pipe, the PVC 90-degree elbow is quickly installed by adhesive bonding, and in combination with the Flexible Metal Hose plastic branch pipe, it ADAPTS to the tiny displacement caused by building settlement. In the pure water system of the laboratory, the PPH elbow is combined with the plastic end of the Flange Adaptor and connected by heat fusion to form a sanitary-grade steering passage, which meets the clean standard.
Connection method: Flexible and adaptable "Installation Solution library"
The connection method of the 90-degree elbow varies with the material and working conditions. The metal elbow with Flange connection is suitable for high-pressure pipelines. At the turning point of the oil transportation pipeline, the flange elbow is fixed to the pipeline flange through bolts and is perfectly compatible with the Flange Adapter . When used in conjunction with Dismantling Joint, it is convenient for regular maintenance. The Bellow Expansion Joint is installed to compensate for the thermal displacement of the pipeline before and after steering, ensuring the connection safety under high pressure.
The threaded connection elbow is suitable for low-pressure small-diameter pipelines. In civil gas pipelines, the 90-degree threaded elbow, in combination with the threaded end of the Flexible Metal Hose, can quickly achieve the turning of the connection pipe of the stove. It is convenient to install and has reliable sealing. The plastic elbow with hot-melt connection is widely used in PVC and PPR pipes. At the turning point of the water supply pipeline in home decoration, the hot-melt elbow forms an integral seal with the pipe. Combined with the Rubber Expansion Joint rubber seal, it achieves double leakage prevention at the turning points of the inlet and outlet water pipes of the water heater.
Scene Adaptation: The "All-Rounder of Transitions" in All fields
The industrial sector is the "main battlefield" for 90-degree elbows. The discharge pipe of the chemical reactor is turned through a 90-degree stainless steel elbow and connected to pipes of different diameters with the Flange Adaptor. The Bellow Expansion Joint compensates for the vibration displacement generated during the operation of the reactor to ensure the precise and controllable transportation of raw materials. At the Valve chamber turning point of the long-distance natural gas pipeline, the alloy steel elbow, in combination with Dismantling Joint, can complete maintenance without interrupting the gas supply. The Duckbill Check Valve prevents the backflow of natural gas and ensures the safety of gas transmission.
90-degree elbows are also indispensable in civilian scenarios. The water circulation pipe of the building air conditioning turns through a 90-degree copper elbow, cooperates with a Rubber Expansion Joint to absorb the vibration of the water pump, and is connected to the indoor unit with a Flexible Metal Hose to adapt to minor displacements. The three work together to enhance the heating and cooling efficiency of the air conditioning. In rural tap water renovation projects, PVC90-degree elbows achieve pipe turning through rapid bonding. Combined with the diameter change function of the Flange adapter, they connect main and branch pipes to meet the water usage demands of different users. The installation cost is much lower than that of metal pipe fittings.
System Synergy: "Steering Efficiency" of Accessory Linkage
The 90-degree elbow doubles its efficiency in coordination with various accessories. In the feed water pipeline system of the high-pressure boiler, Bellow Expansion Joint is installed at the turning point of the alloy 90-degree elbow to compensate for the stress caused by the thermal expansion and contraction of the pipeline. Flange Adaptor ensures the sealed connection between the elbow and the pipeline. The pressure gauge connected to the Flexible Metal Hose monitors the pressure at the turning point in real time; In the aeration pipeline of sewage treatment, the plastic 90-degree elbow is combined with the Rubber Expansion Joint. The former realizes the turning, the latter absorbs the vibration of the aeration fan, and the Dismantling Joint facilitates the regular cleaning of the sludge accumulation at the turning point.
In the clean pipeline of food processing, the stainless steel 90-degree elbow is connected to the Flexible Metal Hose through Flange Adaptor to achieve the turning connection between the equipment and the main pipeline. Its smooth inner wall has no hygiene dead corners and is combined with the food-grade Rubber material of Rubber Expansion Joint. Comply with the hygiene standards for food production. This multi-dimensional synergy enables the 90-degree elbow to maintain efficient steering performance in complex pipeline systems at all times.
The 90-degree elbow, with its precise steering function, diverse material options and flexible connection methods, has become the "master of space optimization" in pipeline systems. It works in coordination with various pipe fittings and can stably play a steering role in scenarios such as industrial high pressure, civil low pressure, and corrosive environments, providing solid support for the flexible layout and safe operation of the pipeline system. It is an indispensable core component for pipeline steering.
