   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. General Steel Arch Bridg

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

  Choosing the  right paint brush  plays an important role in the speed and quality of your work, as the results do vary depending on the type of paint brush you use. If you don't have a quality paint paint brush to hand, the work will look terrible.   It is important to remember that a  good paint brush  can be used again and again when it is properly maintained. You need to keep your paint brushes in tip-top condition.   But what size paint brush do you actually need for different types of paint applications? We've put together a quick guide to help you fill your decorating toolbox with all the quality paint brushes you need to get the job done successfully. What to consider when choosing the best paint brushes Paint brushes  are made from different materials and come in a variety of shapes and sizes to suit specific products and tasks. Here's how to determine what's right for your job.   Materials Paint brush bristles fall into two main categories: natural, which are

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

  Hospital doors include lead doors for X-ray rooms, hospital patient room doors, ICU doors, etc. Good hospital door design plays an important role in preventing cross-contamination as well as providing fire and x-ray protection, maintaining correct room pressures, and ensuring optimum operating efficiency. Doors for hospitals are also being widely used in other places such as medical centers, healthcare centers, or electronic factories.   There are some advantages of Xinyi hospital door design: hermetic seals, eco-friendly, easy to clean, anti-bacteria. As a professional hospital door manufacturer, Xinyi can provide you with different types of hospital doors with different dimensions and parameters at a consistent quality. What Are Hospital Doors Made Of ？ The materials used in hospital doors are HPL, fireproof panel, galvanized steel, stainless steel, etc., among which wood and steel are the most commonly used. The main reason for the use of wood for hospital doors: Considering the p
