  Arch Steel bridge  is a bridge that is made from materials such as steel or reinforced concrete. The deck is within the arch, and cables or beams that are in tension suspend the central part of the deck from the arch. We have professional engineering team to design, manufacture and construct the steel briges of this type. The Arch Steel bridge structure is to convert the vertical load of the deck into a part of the horizontal thrust, and the arch mainly bears the pressure. The arch steel bridge is mainly composed of the superstructure and the substructure. The arch ring of the superstructure is the main load-bearing structure, and the substructure includes the pier, abutment and foundation.   Steel Arch Bridge  Design There are many factors that affect the Steel Arch Bridge Design. In general, these factors are related to function, cost, safety, aesthetics, traffic demand capacity, foundation conditions, erection procedure, clearance requirements, and so on.

Choosing the right  pump  for your slurry application can be a daunting task due to the balance of many factors including pressure, flow rate, abrasiveness, viscosity, particle size and particle type. There are several  types of pumps  suitable for  pumping slurries , but there are some important factors to consider before deciding which technology to use. You can follow these four simple steps to determine which type of slurry pump is best for your particular application. 1. Determine the Nature of the Material Being Pumped Consider the following. Size, shape and hardness of the particles (which affect the potential for wear and corrosion of the pump components), corrosiveness of the slurry. 2. Consider the pump components If it is a  centrifugal pump , is the design and material used to manufacture the impeller adequate to pump the slurry? What types of materials are used to manufacture the pump? Are the pump discharge components suitable for the slurry being pumped? What is the best

Roller bearings  have linear contact, rather than point contact, which gives them greater load carrying capacity and higher impact resistance. The rollers themselves come in a variety of shapes, namely cylindrical and tapered.  Tapered roller bearings  can withstand large thrust loads. Cylindrical roller bearings can only withstand limited thrust loads. Tapered Roller Bearings Tapered roller bearings are radial thrust rolling bearings whose rolling bodies are tapered rollers. There are small taper angle and large taper angle two kinds. Small taper angle mainly bear radial load, mainly radial and axial combined load. Often used in pairs, reverse installation. Inner ring and outer ring can be installed separately. Installation and use of radial and axial clearance can be adjusted; large taper angle is mainly subjected to axial and radial combined load, mainly axial load. Generally not used to bear pure axial load alone. Features of Tapered Roller Bearings Low friction, low noise, low vib

Glass fused steel tank  is made of glass and steel plate, special sealing materials, self-locking screws and other materials. The thickness of the enameled steel plate can be up to 20mm, the most commonly used steel plate thickness is 3~10mm, the surface of the steel plate has oil, contains rust, contains oxidation skin, after the pretreatment process such as shot blasting, sand blasting, the surface of the steel plate will be very clean. After the electric furnace 900 ℃ high temperature secondary enamel, the steel plate on both sides of the enamel coating of 0.3mm. The bond between the enamel coating and the steel plate is strong. The enamel coating not only prevents corrosion of the tank, but also has the effect of resistance to strong acid and alkali. And has extremely strong wear resistance. Large-capacity storage tanks are an important infrastructure for petroleum, chemical, fire, food processing, sewage treatment, gas and other industries, storage tanks play an important role in

A new shower can take your bathroom from boring to glamorous. There are so many possibilities for your  shower glass door  design that you may not know where to start. Before making a decision, you may be wondering if you should purchase framed or frameless glass shower doors.We've summarized the pros and cons of frameless and framed shower doors. Commonalities Both are made of tempered glass. They are available in a variety of glass designs. The doors open in many different ways. Framed and frameless shower doors can be sealed with a protective coating. Both types of doors require caulking. Both types of doors can provide a good view of the shower stall.  Difference Materials Framed doors are made of thinner glass, as the frame supports the door. The frame itself is usually made of aluminum and can be powder coated in a variety of colors and finishes. The frame can be smooth or textured, and the glass is sealed in the frame to prevent leakage. Frameless doors are made of the same

    What is a sandwich panel? A  sandwich panel  is a product used to clad the walls and roofs of buildings. Each panel comprises a core of thermoinsulating material, skinned on both sides with sheet metal. Sandwich panels are not structural materials but curtain materials. The structural forces are carried by the steel framework or other carrier frame to which the sandwich panels are attached. The types of sandwich panel are generally grouped by the thermoinsulating material used as the core. Sandwich panels with cores of EPS (expanded polystyrene), mineral wool and polyurethane (PIR, or polyisocyanurate) are all readily available. The materials mainly vary in their thermal insulating performance, sound insulating performance, reaction to fire and weight.   Why use sandwich panels anyway? Sandwich panels are widely acclaimed due to a number of benefits, mainly those related to cost. Comparisons between frame or stud partition technology (frames lined with sandwich panels) and traditio

    With the continuous progress of the world and the rapid development of science and technology, the stone carving industry has gradually developed, and there are more and more types of stone carvings, each of which has its own characteristics and value. Most of the stone sculptures that we often see in our daily life are made of marble. These marble sculptures have different shapes and colors, play a decorative role in our lives, and are deeply loved and favored by people. So, do you know what are the characteristics of  marble sculpture ? Here is a brief introduction to you: Marble is a metamorphic or sedimentary carbonate rock, which belongs to medium-hard stone. Its chemical composition is mainly calcium carbonate, and its density is generally 2500-2600kg/m. The marble crystal particles are directly combined into an overall block structure, the texture is tight but the hardness is not large, the water absorption rate is less than 10%, the wear resistance is good, weak acid and al

The medical door is one of the essential equipment in the hospital. The medical door is different from our household door, it needs to have the performance of resisting corrosion, bacteria and collision. Since the hospital itself is a special place, the characteristics of the medical door should be consistent with the characteristics of the hospital. What factors affect the price of hospital doors? The following is a discussion of this issue.   Wheelchairs, stretchers, and transportation tools go in and out of the medical door almost every day, so it is difficult to avoid hitting the door and door frame. Even if the door is put into use in a short time, the door and door frame will be damaged to varying degrees. Due to the particularity of the door, its application characteristics need to be met in the design and manufacture, and the price depends on the design characteristics of hospital doors for sale.     Ⅰ . The price of the hospital room doors   depends on the design characteristi

Wheat is one of the most consumed grains in the world. It comes from a type of wheat that is grown in countless varieties around the world. In the beginning wheat grinding required manual grinding, but with the development of technology it is now possible to grind large quantities by  wheat flour milling machines , which has greatly increased productivity. Flour milling  is the process of grinding the grain into flour. Milling of wheat involves separating the bran and germ from the endosperm and reducing the endosperm to fine flour. It can be divided into the following steps. Step 1: Cleaning Sticks, stones and other such impurities are removed from the wheat. Then, the whole pure wheat is sent to the conditioning tank for further processing. Step 2: Tempering and Conditioning At this stage, the wheat is soaked in water in order to easily remove the bran. Conditioning is done prior to milling to ensure uniform moisture content throughout the grain. The moisture helps prevent the bran f

FRP Molded Gratings FRP (fiber-reinforced plastic)  is an alternative to flooring products such as aluminum or stainless steel grating to prevents caustic or corrosive environments. FRP is used for flooring, especially for access walkways, platforms, screening, battery racks, bridges, and stair treads.  FRP grating  is available in various resins, standard and custom colors, depths, panel sizes, and mesh configurations. Surface options include a meniscus or integrally applied grit top, which offers superior, slip-resistant footing. FRP molded gratings are used in place of traditional materials.     Advantages of FRP Molded Gratings ● Corrosion Resistant ● Bi-directional Strength ● Slip Resistant ● Low Maintenance ● High Strength to Weight Ratio ● Fire Retardant ● Lightweight ● Impact Resistant ● Long Service Life ● Superior Ergonomics   Pultruded  Fiberglass Grating Process A machine that operates much like a caterpillar in form, first grabs the raw materials (resin and glass).

Bagasse is a by-product of sugar production. Bagasse is the fiber that remains after extraction of juice from sugarcane. The remaining fiber is pressed into forms in a high-heat, high-pressure process using considerably less energy compared with pulping wood for paper products.    Since it is a waste by-product, it does not require additional cultivation lands and has no impact on the area of forests. Bagasse products are biodegradable in commercial compost facilities for up to 90 days. These 100% compostable bowls will degrade back to organic compost material and can then be used for fertilizer. Food trays made from bagasse are thicker and more rigid than traditional paper or plastic trays. They have ideal thermal properties for hot, wet or oily foods. You can even microwave them for 2-3 minutes. Microwave safe and freezable, can be used for both hot and cold items Soak proof Requires no plastic or wax lining Sturdy and not very flexible Suitable for temperatures from -25°C to 220°C W

  Tubular Locks Tubular locks  are a bored lockset. In the edge bore of these locks, a latch or bolt mechanism is installed. A tubular lock is also known by the names- radial lock, ace lock or a circle pin tumbler. Tubular locks have got their name from the shape of the keyway which is circular. The tubular locks have a basic ring-shaped hole and in the middle it has a solid metal cylinder. There are about seven or eight pins in the ring gap. In a tubular lock the key pins are moved horizontally. The lock has grooves cut into the outsides of the ring shape. There is a specific way in which the key has to be inserted in the lock. The tubular locks provide light – medium duty. They have a smaller rose and come in market with decorative levers. However, they have limited cylinder options, cannot be used on thick doors and the chassis is not operational. Applications– Often used for unattended commercial products. They are used in Bike locks, ATM’s, vending machines.   Cylindrical Locks Cy
