Polypropylene or PP fabric is a type of textile that’s said to have many uses in various industries worldwide. It’s created through the production of specific oil and gasses. Then, they’re woven into fabrics ready for use.  Without undergoing prior chemical treatments, untreated PP fabric can be both bleached and cleaned; more processes may be done for further refining the product. The fabric is also known for its strength and utility, hence, many in the construction industry prize it for its benefits. The following points pertain to how different construction companies are using the material for a variety of purposes.  1. Rubble Mound Creation  Polypropylene fabrics are used in geotechnical engineering, a branch of engineering that involves the earth, materials related to the soil, and their behavior when used in construction. Coastal drilling and mining are just some of the activities that fall under the said category. PP’s also known as a geotextile or a special type of fabric favored for its geosynthetic feature and superior filtering capabilities.   Woven polypropylene fabric suppliers can create tear-resistant, mildew-resistant, high-strength, and lightweight materials that can withstand stretching and shrinking. The fabric prevents the mixing or transferring of delicate material like soil and sand with rocks or gravel.   It’s advisable that the material itself, however, needs to be protected by small stones that help prevent damage from rocks and blocks. Polypropylene is sometimes mixed with other similar geotextiles such as polyamide and polyethylene to enhance its usefulness and serve more specific tasks.    The synthetic fabric is used at beaches wherein it replaces rocks in locations that lack quarries. They can also be used as primary materials for the construction of rubble mound breakwaters to prevent the impact of ocean waves in coastal erosions and the transportation of sediments.   2. Flood Control  Locations that are constantly battling extremely wet weather conditions can use sandbags to protect different establishments. Polypropylene fabrics can be turned into sandbags. However, they’re not to be confused with earthbags for the two are different from each other. Sandbags are believed to be helpful flood control solution examples to prevent the flow of water as much as possible.   You can place sandbags in front of entrances and indoor water drainages such as the restroom and laundry room in your home. Sandbags are especially useful when the structure is made of fibro-sheeting or wood materials.   It’s important to note that this type of bag must only be filled with sand and not with clay, soil, or gravel as they’ll not hold water. They can go as heavy as 20kg and must be laid on top of a plastic sheet like you would with bricks where the unfilled part of a sandbag is topped with the filled end of another.  3. Fences And Screens    Polypropylene is one of the most widely used plastic materials in the world. It’s also used as a means to secure construction sites by keeping unauthorized persons out. Construction locations can be dangerous, and the use of polypropylene fences or screens is a safe and temporary alternative to other types of blockers a construction manager may use.   They’re economical and don’t cause harm to both motorists and pedestrians. Constructions sites also use them for aesthetic reasons as they can help block out the unsightly environment of the site from onlookers and passersby.   PP fabrics are regarded as a great material for construction fences because they’re resistant to the seasons and changing daily weather conditions. Their heat-enduring features prevent them from chipping or flaking that makes the covers long-lasting. In addition, they contain pigments and fillers that block out UV rays or ultraviolet radiation to protect both workers and the construction from possible damage.  4. Silt Fences For Erosion Control  Polypropylene silt-films are temporary shields used in construction sites to help prevent ground sediments from breaking or falling apart. It’s an essential tool for areas near bodies of water as it prevents the contaminated soil from eventually seeping into the water.  PP’s a durable material that’ll last up to six months with good care. They also make great temporary solutions to fencing because they’re easy to remove and can’t have a lasting effect on the environment.   Silt fencing can be a construction of wood and geotextiles like polypropylene material. They’re also resistant to water as it’s believed that they can withstand the pressures brought upon by a cubic foot of water.   5. Road And Railway Construction  Geotextiles like polypropylene fabrics, also called geotechnical materials mixed with other plastics, are also used to construct roadways and railways that make travel easier and faster. These unique types of fabrics are utilized to stabilize substrates or underlying layers of substances such as soft or uneven terrain underneath a construction feature.   In road construction, geosynthetic fabrics are laid out over muddy and unstable soil. Heavy machinery then spread out a subbase layer of rock or gravel on top. The plastic fabric helps prevent the subgrade material from sinking into the muddy ground. The area then becomes leveled and lowers the need for more maintenance work in the long run.   PP fabric is also placed between a layer of substrate underneath. A ballast layer is set on top to maintain structural integrity under the tracks. Railways tend to degrade over time because of subgrade cohesion. Geotextiles make it easier to save on labor costs because it puts a long gap between the maintenance periods of rail tracks.  Polypropylene combination fabrics can help prevent the subgrade underneath from pumping when trains travel on the tracks. The reinforcement barrier can help strengthen the layered elements to make them safer and sturdier throughout the years.  6. Earthbag Construction  Polypropylene fabrics can be made into earthbags that are used for home construction. They’re economical alternatives to conventional blocks and bricks but are also durable and holds well against water damage and rotting. They can be eco-friendly too as some earthbags are mixed with portions of clay and burlap or hemp. Some earthbags also come with UV protection.   No energy

A flow meter is a machine that measures the density or velocity of fluids or gases. They are also known as flow rate sensors, flow indicator, flow gauge, liquid meter, etc. Flow meters are mostly used to measure the fluids or gases that flow within a pipe.   There are several options in flowmeters, such as magnetic Coriolis, single-use, variable area, etc. However, they can be different in price, accuracy, and functionality. Ultrasonic flow meters are an extremely accurate and multi-use option but tend to be quite expensive. For a low-price option with better accuracy, you can choose single-use turbine sensors. But they are only good if the working fluid is low viscous. For higher viscous flowing liquid, disposable ultrasonic meters are a good choice for single-use.  Things to Consider while Choosing a Flow Meter Type of Flow Measurement. Volumetric or Mass Flow, Momentum or Velocity. Type of Media. Liquid, gas, or slurry. Media Conditions. Temperature and pressure of the media and whether the conditions remain the same or change with time. Accuracy. Accuracy level required for the readings. Flow Range. Requirement of minimum and maximum readings in the flow range. Geographical Conditions. Clean installation, tamper proof-readings, ATEX zone installation, etc. Flow Meter Options Available 1. Ultrasonic Flow Meters. These are more advanced and flexible than other flow meters. They measure the frequency of ultrasonic waves passed through the fluids. Two popular categories of ultrasonic flow meters are Transit-time and Doppler. Doppler meters use particles in the liquid by their reflection mechanism to measure the speed of the liquid. The Transit-time meter measures the difference in frequencies of forward and reverses signals passed through the clean liquid. Transit-time works best in clean fluids without any particles or solids. As they are flexible, ultrasonic flow meters are widely used in many industries. That includes facilities management, chemical, paper and pulp, and mining sectors. Petrochemical, water, wastewater, and aquafarms also procure the technology. 2. Coriolis Flow Meters. They provide the measurement of true-mass flow from two designs: a single tube and two parallel tubes. They work through an oscillation that is induced within the tubes at indicated frequencies. It is based on Newton’s Second Law of Motion, the frequency of oscillation changes with a change in flow rate. Coriolis flowmeters are best suited for growing and broad collection of liquid and gas applications. They give multi-parameter details on temperature, density, and mass. Mainly used in the wastewater treatment facility, pharmaceutical manufacturing, gas facility, and nuclear facility 3. Gear Flow Meters. These use oval-shaped gears that are interlinked and rotates when liquid passes through them. The volume of fluid that passes through the oval gears is well controlled, which gives the meter higher accuracy. The structure is simple and rugged, which delivers the flexibility of installation in most types of environments. Gear meters are best suited for high-viscous fluids. The gear meters work well in the paper and pulp industry, oil and fuel transfer, and manufacturing. Because of stainless steel gears, they are best suited for petrochemical and any environment dealing in light to heavy oils.  4. Magnetic Flow Meters. They are also known as Magmeters and found in two types: full-bore and insertion. Magmeters work by assessing the electric content present in water or other fluids. The technology has no moving parts, and full-bore types provide no intrusion in the fluid stream. Magmeters are used in water purification, mining, food and beverage, paper and pulp, petroleum, and chemical industries. The use of Magmeters should be prevented in low-conductive liquids like de-ionized water. 5. Turbine Flow Meters. They have a bladed rotor connected to a centerline of a flowing stream. The rotator section provides a pulse while moving either an optical or a magnetic sensor. The pulse frequency is directly linked to the velocity of the liquid. Some turbine meters give higher accuracy and can deal with higher-viscous fluids. Two main applications for turbine flow meters are water purification and irrigation. However, they can also be applied in wastewater, utilities, and oil and gas industries. If accessed with proper sanitized connections, they manage flow in the food and beverage sectors. Not suited for a low-flowing stream. 6. Vortex Flow Meters. They use pressure sensors for measuring pressure pulse.  Pressure pulses are measured from vortices, which come from the flowing liquid passing a bluff object. A simple explanation for this can be the waving of the flag. The pulses and rate of flow are directly proportional. Although the vortex flow meter is lesser-known, it provides higher accuracy. The design is perfect for high-purity and aggressive applications. These meters are suitable for wastewater, food and beverage, oil and gas, and water industries. They can also be applied to chemical, utilities, and water purification. Be Wise While Choosing Flow Meters Although all the flow meters have their unique features, you must choose a flow meter wisely and based on your requirements. Consider factors like usage, sanitization, place of installation, pricing, maintenance, viscosity, temperature, etc., before making a decision. Make your choice that’s wide enough to cover your needs. The measurement accuracy depends on several factors. A low-cost, lower-quality meter will give lower accuracy results, while the same is true the other way around.
