Corrugated steel hose is a kind of high-quality flexible pipe in modern industry pipeline. As a result of austentic stainless steel manufacture,the hose has good flexibility, fatigue resistance, hot and low temperature resistance, corrosion resistance, and many other features.
The ripple compensator belongs to a compensation element.The effective expansion and deformation of the bellows of the working body is used to absorb the size changes caused by thermal expansion and cold contraction of pipelines, conduits and containers, etc., or to compensate the axial, transverse and angular displacements of pipelines, conduits and containers.It can also be used to reduce noise and vibration.It is widely used in modern industry.
VSSJAFC type detachable double flange force transmission joint is composed of loose sleeve expansion joint, short pipe flange, force transmission screw and other components. It can transfer the pressure thrust of the connected parts (blind plate force) and compensate for pipeline error, and cannot absorb axial displacement.Important for pump, valve, pipeline and other accessories loose sleeve connection.
The double flange limit expansion joint is composed of main parts such as body, sealing ring, gland and extension shortening pipe.On the basis of the original performance of the loose sleeve expansion joint, a limit device was added, and the maximum expansion was locked with a double nut.The pipe can expand and contract freely in the allowed expansion and contraction quantity, once exceeds its maximum expansion and contraction quantity, plays the limit position, ensures the safe operation of the pipe, especially suitable for the connection of the pipe with vibration or certain inclination and turning.
Duct rubber compensator is divided into FDZ, FVB, FUB, XB four kinds of models, from rubber and rubber fabric composite material, steel flange, socket, thermal insulation materials, mainly used for a variety of flexible connection between fan, air duct, its function is sealing, shock absorption, noise reduction, medium resistance, displacement and makes the pipes easier to install, is an extremely ideal environmental protection field shock absorption, noise reduction, the best accessories and smoke prevention and dust control.
The rounded rectangle compensator adopts rectangular section and rounded waveform. The single expansion joint in the pipeline bears two-dimensional displacement.The elbow joint pipe composed of two expansion joints can withstand three dimensional displacement.
Multifunctional universal joint, this product is suitable for seamless pipe, welded pipe, ductile pipe, cast iron pipe (PVC, PPR, PE pipe, steel-plastic pipe)
Multi-function universal connection elbow, this product is suitable for seamless pipe, welded pipe, ductile pipe, cast iron pipe (PVC, PPR, PE pipe, steel plastic pipe), the emergency repair with water pressure operation, no electricity, only a wrench quick connection repair, the pipe has telescopic anti-detrench effect, reduce telescopic device, excavation area is very small.
This product is suitable for seamless pipe, welded pipe, ductile pipe, cast iron pipe (PVC,PPR,PE pipe, steel-plastic pipe). It can be operated with water pressure in rush repair without using electricity. It only needs a wrench to quickly connect and repair.
Double orifice kinetic air valve, For water...
Double port exhaust valve, also known as double port exhaust valve.It is suitable for the industrial medium as water pipeline, as a rapid removal of gas in the pipeline equipment.It is also a necessary equipment to improve the efficiency of water transport equipment and protect the pipeline from deformation and fracture.
X43W|X43T type plug valve is suitable for opening and closing of water, oil, gas and other medium pipelines with nominal pressure of 0.6-1.0mpa and temperature ≤100℃
Plug valves are shutoff or plunger shaped rotary valves that open or close a valve by rotating 90 degrees so that the port on the plug is identical to or separate from the port on the body.
Two - way internal thread plug valve suitable for media: water, gas, steam, oil, nitric acid, acetic acid,etc.
Three - way internal screw plug valve in the pipeline is mainly used for cutting, lifting and changing the direction of medium flow.
The purpose of three-way all-copper plug valve is to be installed in the pipeline mainly for cutting, distributing and changing the direction of medium flow.
Two - way insulation plug valve is an industrial equipment parts, composed of valve body, plug, etc.
The opening and closing part of the insulation plug valve is a perforated cylinder that rotates perpendicular to the axis of the passage to achieve the purpose of opening and closing the passage.
Oil-sealed plug valve is suitable for cutting off or connecting the pipeline medium under nominal pressure PN10, working temperature -29 ~ 100℃ in urban construction, chemical industry, metallurgy, petroleum, pharmaceutical industry, food, beverage, environmental protection industry and other working conditions.
Asphalt special valve (also known as plug valve) belongs to the valve, its opening and closing parts (conical plug or ball) around its own center line rotation plug valve is used with the plug with a through hole as the opening and closing parts, through the rotation of the plug body and valve stem to achieve the opening and closing action of the valve.
