Depth Filtration Using Pure Cellulosic Filter Sheets During depth filtration the solid components, fine turbidities and micro- organisms contained in the product - depending on the grade of filter sheet used are removed from the liquids to be filtered. As the liquid enters the filter sheet it is divided into many tiny streams. The direction of flow of the tiny streams is permanently diverted through the filter sheet’s random structure. This way, micro-organisms and tiny turbidity particles are mechanically trapped in the filter sheet’s pore matrix as it gradually becomes narrower. Applications Pure Cellulose filter pads and sheets for Pharmaceutical, Biotechnology, Chemical, F&B, Breweries , Wine Manufacturing , Distilleries, and Cosmetics Industry Examples of industries: Biotech Beverage (beer, wine, spirits, juice...) Enzymes Fine chemicals Herbal or other natural extracts Pharmaceutical intermediates Process water Solvents COCO

In recent years, mobile robots have moved far beyond clean factory floors. They now travel through loading docks, outdoor walkways, food‑processing areas, and chemical storage zones. As their operating environments diversify, one component quietly takes on far more responsibility than most people realize, the wheel shaft skeleton oil seal. For engineers who work closely with AGV and AMR drive systems, the question is no longer whether a seal can prevent lubricant leakage. The real challenge is whether it can remain stable while the surrounding environment keeps changing. Dust, moisture, chemical residues, and mechanical shock all influence how the sealing lip behaves over time. Indoor facilities with smooth, clean floors present the least aggressive conditions. Here, the seal mainly deals with fine airborne dust. A consistent lip‑to‑shaft contact pressure and a wear‑resistant elastomer —  typically NBR or HNBR — are enough to maintain performance. A light dust‑lip design adds an extra layer of protection without increasing friction. The situation shifts once the robot enters mixed‑surface outdoor areas. Mud, water, and coarse particles interact in unpredictable ways, and the seal must withstand both contamination and rapid humidity changes. Materials with stronger weather resistance, such as FKM or reinforced HNBR, tend to perform better. Dual‑lip configurations help keep mud and water out, while corrosion‑resistant metal cases prevent long‑term degradation. Environments with high humidity or chemical exposure introduce a different set of risks. Food‑processing plants, for example, require frequent washdowns, and chemical warehouses may expose seals to cleaning agents or vapors. In these cases, the elastomer’s resistance to swelling and chemical attack becomes the deciding factor. EPDM, FKM, or specialized chemical‑resistant compounds are commonly used. Increasing the lip preload helps the seal withstand high‑pressure water jets during cleaning. Heavy‑duty AGVs and fork‑type AMRs add yet another layer of complexity. Their wheel shafts experience frequent micro‑movements due to load variations, which can accelerate lip wear if the seal structure is not robust enough. A reinforced metal case, a stronger spring, and abrasion‑resistant lip materials help the seal maintain stability even when the shaft is not perfectly steady. Across all these scenarios, one principle remains consistent: a reliable sealing system is the result of coordinated decisions, not a single design choice. Understanding the robot’s operating environment, selecting materials, accordingly, ensuring proper shaft stability, and maintaining regular inspection routines all contribute to long‑term performance. As mobile robots continue to expand into new industries, the expectations placed on wheel‑shaft oil seals will only grow. The more accurately we match seal design to real‑world floor conditions, the more confidently these robots can operate in the environments we ask them to navigate.

There are 45° short radius elbows and 45° long radius elbows. Long radius elbows(LR elbow) provide smaller flow resistance and pressure loss, and are suitable for general piping systems; Short radius elbows (SR elbow) are suitable for limited space or situations that require faster changes in flow direction. Ideal for industries that require robust, leakproof connections, such as oil, gas, and wastewater management. Buttweld is used to connect the ends of pipes and fittings by a butt welding process. Also known as welded pipe fittings. It has ended in beveled or plain, dimensions normally from 3/4” to 24”. Manufactured according to ASME B16.9. In various materials like carbon steel , alloy steel, and stainless steel. The butt weld elbow is designed to change the direction of the fluid in the piping system. It has a long radius (LR) and a short radius (SR) elbow types and has different degrees of coverage to 45 degrees, 90 degrees, and 180 degrees. Buttweld elbow is a steel elbow formed by hot pressing or forging. Its connection form is to weld the elbow and steel pipe directly. Butt-welded elbows are mainly used for elbows with higher pressure and temperature than other connection types (socket welded elbow or threaded pipe elbow).

Choose a trusted 180° Elbow to ensure safety and performance in demanding applications. There are 180° short radius elbows and 180° long radius elbows. Long radius elbows provide smaller flow resistance and pressure loss, and are suitable for general piping systems. Short radius elbows are suitable for limited space or situations that require faster changes in flow direction. They are commonly used in situations where there is a need for a significant change in direction, causing the fluid to flow in the opposite direction. It is connected to the pipe by welding. It has high strength and sealing performance, and can withstand high pressure and temperature. Made of materials such as stainless steel, duplex steel, or special alloy steel, it has corrosion resistance and can resist corrosion from oxidizing agents, acids, alkalis, salt solutions, and other corrosive media.

The absence of any weld seams in seamless steel pipe elbows enhances their structural integrity and resistance to leaks, making them ideal for high- pressure and high-temperature applications within the Seamless Steel Drawing Pipes industry. Rayoung is one of the leading manufacturers of buttweld steel Seamless pipe elbows. Standard and customized degrees are acceptable. Since most of the pipe fittings are used for welding, in order to improve the welding quality, the ends are beveled, leaving a certain angle and a certain side. This requirement is also relatively strict, such as how thick the side is, how much the angle is and the deviation. The scope is specified. The surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the steel grade of the pipe fittings and the pipes to be connected is the same. Rayound is one of the leading manufacturers of buttweld Seamless steel pipe elbow. Standard and customized degrees are acceptable. 36-years experience in manufacturing and supplying carbon steel seamless and welded pipe fittings and forged flanges.
