90° Elbow

The 90° elbow is one of the commonly used accessories in the pipeline system, mainly used to change the direction of the pipeline. Its bending angle is 90 degrees, usually used for sharp turns of the pipeline or occasions where a large angle of turn is required. The 90° elbow can help the pipeline system to smoothly complete the direction adjustment, especially in the case of limited space or complex pipeline layout, it can effectively optimize the pipeline direction. It is widely used in the petroleum, chemical, electric power, construction, water supply and drainage and other industries, suitable for various fluid media, pressure and temperature conditions.

Tee

Tee is a commonly used pipe fitting, used for flow diversion, convergence or direction change in the pipe system. The function of the tee is to connect three pipes, which can be a straight connection or a branch connection, so as to achieve the distribution and convergence of fluids in the pipe. According to the different needs of the pipe, there are different types of tees, such as equal diameter tees (T-type) and reducing tees (reducing tees). It is widely used in industries such as petroleum, chemical, electric power, construction, water treatment, etc.

Neck welding flange

Neck welding flange is a flange commonly used in high-pressure pipeline systems. It has strong pressure resistance and good sealing. The flange is welded to the pipeline through the flange neck and can effectively withstand the high pressure and high temperature in the pipeline. Neck welding flange is widely used in petroleum, chemical, metallurgy, electric power and other industries, and is suitable for pipeline systems that need to withstand high working pressure and temperature.

Concentric reducer

Concentric reducers (also called concentric pipe fittings or concentric pipe transition joints) are a type of connection fittings commonly used in pipeline systems. They are mainly used to connect pipes of different diameters and have the function of transitioning fluids from one pipe to another. Unlike eccentric reducers, the centers of the two pipe ports of concentric reducers are located on the same straight line, so "concentric" means that its inner and outer walls and axis are collinear. It is usually used in various pipeline connections and can smoothly change the diameter of the pipeline to ensure stable delivery of the fluid. Concentric reducers are widely used in the fields of petroleum, chemical industry, electric power, metallurgy, water supply and drainage, shipbuilding, etc., especially in places where pipeline size transition is required, such as the connection of fluid pipelines and gas pipelines.

Pipe bending

The elbow (also called elbow pipe) is a key fitting used to change the direction of fluid flow in a piping system. It can turn the pipe from one direction to another and is often used to connect different parts of a piping system or change the direction of the pipe layout. The main function of the elbow is to achieve the turning of the pipe, avoid the waste of space in the straight pipe layout, and ensure the smooth flow of the fluid in the pipe. The elbow is generally classified according to parameters such as the bending angle, radius, material and caliber. Common elbow angles include 45°, 90°, 180°, etc. Pipe elbows are widely used in various types of pipeline systems such as petroleum, chemical, electric power, construction, water supply, and drainage.

Threaded flange

Threaded flange is a pipe flange connected by threads. It is widely used in industries such as petroleum, chemical, electric power, and shipbuilding to connect pipelines or equipment. The main feature of threaded flange is that it does not require welding and is directly connected to the pipeline through threads, which is easy to disassemble and install. This flange is widely used in low-pressure systems and pipeline connections, especially in places where welding is not suitable.

Blind Plate

A blind flange is a flange without holes, usually used to close ports or openings in a piping system. It is used to prevent leakage of fluids or gases during pipeline installation, overhaul, shutdown maintenance or testing of pipeline systems. Blind flanges are generally bolted to flange joints to tightly close the openings of pipelines or equipment. Blind flanges are critical sealing components in pipeline systems and are widely used in industries such as petroleum, natural gas, chemicals, and electric power.

Pipe cap

Pipe caps (also called pipe caps or pipe plugging caps) are a type of sealing device in a pipeline system, mainly used for closing the end of a pipeline or temporarily plugging it. It can effectively seal the pipeline opening, prevent external pollutants from entering the interior of the pipeline, and prevent leakage of media in the pipeline. Pipe caps are widely used in industries such as petroleum, natural gas, chemicals, electric power, and metallurgy, and are often used in pipeline construction, maintenance, pressure testing, storage, and transportation. Pipe caps are usually designed to be closed and can be installed by welding, flange connection, threaded connection, etc. to ensure the tightness of the pipeline system after closure. The shape of the pipe cap can be round, spherical, elliptical, etc. The specific shape and size are customized according to the pipeline specifications and usage requirements.

Loose flange

Loose flange is a pipe connection flange that does not require welding and is mainly connected to the pipe by bolts and gaskets. Unlike traditional welded flanges, the design of loose flanges allows a certain amount of loose space between the flange and the pipe, so that the flange can be easily disassembled and replaced. It is widely used in pipeline systems that need to be regularly disassembled, inspected or repaired, especially for medium and low pressure pipelines and working conditions. The advantages of loose flanges are the ease of installation and disassembly, reduced maintenance costs and flexibility. They are widely used in many industrial fields, such as chemical, electric power, oil and gas, water supply and drainage and other pipeline connection systems.

Plate type flat welding flange

Plate-type flat-weld flange is a common pipe connection flange with the characteristics of simple structure, low cost and convenient installation. It is suitable for pipeline systems with low to medium pressure and is widely used in industries such as petroleum, natural gas, chemical industry, and electric power. Plate-type flat-weld flange is connected to the pipeline by welding, without the need for additional threads or holes, ensuring the sealing and stability of the connection.
