DESCRIPTIONS
LANDYOUNG GRP cable tray is a composite material profile made of E-glassfiber, polyester resin or vinyl resin or epoxy resin or phenolic resin, flame retardant by pultrusion process or SMC process.
Application
Due to the low thermal conductivity of the selected materials and the addition of flame retardants, the product not only has fire resistance, heat insulation, self-extinguishing properties, but also high corrosion resistance, but also has light structure, aging resistance, safety and reliability. And other advantages, it can be conveniently used in conjunction with metal bridge frames and used in strong corrosive environments such as chemical industry, metallurgy, and petroleum.
Advantages and features
- GRP cable tray is suitable for the laying of power cables with voltages below 10 kV, as well as control cables, lighting wiring, pneumatic and hydraulic pipe cables, and other indoor and outdoor overhead cable trenches and tunnels.
- FRP cable tray has the characteristics of wide application, high strength, light weight, reasonable structure, low cost, long life, strong corrosion resistance, simple construction, flexible wiring, standard installation, and beautiful appearance. Expansion cables, maintenance and repair are all convenient. The installation FRP cable tray can be adapted to local conditions.
- FRP cable tray can be installed overhead with process pipelines; slabs and beams are hoisted; indoor and outdoor walls, column walls, tunnels, and cable trench walls are side-mounted, and can also be installed on open-air columns or piers. When hoisting large multi-layer bridges, I-steel columns should be laid symmetrically on both sides as far as possible.

The copper alloys chosen for the moulds must maintain their physical properties at the operating temperatures of the continuous casting process.
The temperature gradation from the inner wall of the mould to the outside face of the mould can cause serious distortion problems, and Metallurgical Copper Mould Tube is imperative that the correct alloy is chosen for the various operating conditions.
Square Copper mould tube STANDARD MATERIALS
Phosphorus de-oxidised copper
This alloy has been proven to be excellent for the manufacture of moulds in the continuous casting of billets. The main composition of this alloy are Cu +Ag 99.90min, P0.0015 / 0.040.
Copper -Silver alloy
The addition of a small amount of silver, whilst not increasing the melting point of copper, does increase the recrystallisation temperature by almost 100℃, and also helps to give better thermal conductivity at the operating temperatures.
This alloy is normally used in moulds for the continuous casting of blooms and slabs .In this case, the moulds are much thicker than in the billet moulds, and the moulds temperature can be higher. The main composition of this alloy are Cu+Ag99.90 min. Ag 0.08 / 0.12 O 0.004 / 0.012.
The continuous casting of molten steel into billets, blooms and slab products, has been highly refined over the years into an extremely sophisticated system. The continuous casting process is expected to produce metallurgically sound products at the lower possible cost, and this is being achieved in many steelworks throughout the world.
Copper moulds have played an important role in the development of the continuous casting process. Their funcition is to receive the molten steel and to allow rapid heat transfer from the steel to the cooling water to enable quick solidification.
The mould must exhibit excellent thermal conductivity, be resistant for thermal erosion ,and be resistant to distortion from thermal stress. So far only copper and a few copper alloys meet the above conditions, both economically and technically.
Mould cooling jacket supplier SOLIDIFICATION
The rate of solidification in the continuous casting process dictates the speed of production. The molten steel, which is in contact with the inner faces of the copper mould, starts to sllidify as rapidly as the heat is extracted, forming a shell. The shell increases in thickness as more heat is extracted, and eventually total solidfication is achieved. the process is similar to the solidification of ingots in ingot moulds. In continuous casting, the whole process is speeded up, with the aim to produce and homogeneous shell growth. Consequently, the mould is an important part of the continuous casting process, and the manufactured quality of the mould plays and important role in their length of life.
INNER SURFACE COATINGS
Over the years, Metallurgists and Engineers have been working together to develop better continuous casting moulds. The steel companies require a more economical mould which will give a longer service life. Surface coating of the inner walls of the mould has given the best results to date. Coatings available are Chromium and Nickel plating. Also, a combination of the two give good results on slab casting.

AQE Gate valves are used to limit the flow of fluid flowing straight through the pipeline. This is an effective and reliable way to stop fluid flow. The Slab Gate Valve can be fully opened or fully closed. The slow opening and closing of the valve helps avoid hydraulic hammers, which can damage the pipes connected to the valve. Gate valves are not used for throttling, so do not let them half open. The gate valve has 3 important parts. They are doors, stems and hoods.
The gate can be used in several variations in a gate valve. You may occasionally use knife doors, or if you use crude oil, you may see flat doors. However, in the marine industry, the most common gate is the wedge. This type of gate valve wholesale uses a wedge-shaped metal sheet that can be moved into the valve body to prevent fluid flow. This uses metal-to-metal contact to create a positive pressure seal. However, under extremely low pressure (5 psi or lower), the gate valve may leak a little.

What is Gate valves
Gate valves are widely used for all types of applications and are suitable for both above-ground and underground installation. Not least for underground installations it is paramount to choose the right type of valve to avoid high replacement costs.
Gate valves are used to shut off the flow of liquids rather than for flow regulation. When fully open, the typical gate valve has no obstruction in the flow path, resulting in very low flow resistance. The size of the open flow path generally varies in a nonlinear manner as the gate is moved. This means that the flow rate does not change evenly with stem travel. Depending on the construction, a partially open gate can vibrate from the fluid flow
Gate valves are mostly used with larger pipe diameters (from 2″ to the largest pipelines) since they are less complex to construct than other types of valves in large sizes.
Main gate valve parts of a gate valve are: body, seat, gate, stem, bonnet and actuator. The main operation mechanism is very simple. When the handwheel is turned, it rotates the stem, which is translated into the vertical movement of a gate via threads.
There are three ways to classify the gate valve.
Types of Disk
Solid taper wedge
Flexible wedge
Split wedge or Parallel disks Valve
Types of Body Bonnet Joint
Screwed Bonnet
Bolted-Bonnet
Welded-Bonnet
Pressure-Seal Bonnet
Types of Stem movement
Rising Stem or OS & Y Type (Outside Stem and Screw Type)
Non-rising Stem type
Gate valvesare used in almost all fluid services such as air, fuel gas, feedwater, steam, lube oil, hydrocarbon, and all most any services.
Some special gate valve is used in slurry and powder product also such as knife gate valve
