Fiberglass flanges are indispensable key connecting components in fiberglass piping systems, used to connect and seal pipe sections to each other, and pipe sections to valves, pumps, or other equipment. There are two main types of fiberglass flanges, which differ in structure and performance: 1. Integral Flange Advantages: Highest strength: Integral molding, good structural integrity, and strong load- bearing capacity. No leakage path: Avoids the bonding interface, resulting in extremely high sealing reliability. Good fatigue resistance: Better able to withstand vibration and pressure fluctuations. 2. Adhesive Flange / Loose Flange Manufacturing process: The flange is manufactured separately from the pipe, and then a high-strength adhesive is used to bond the flange to the outer wall of the pipe.

Fiberglass horizontal storage tanks are made of glass fiber reinforced plastic and installed with their main axis parallel to the ground . They are typically manufactured as a single unit in the factory and then transported to the site for installation and use. The main manufacturing process involves fixed-length winding combined with hand lay-up to produce end caps and installation accessories. Structural design features Tank body : Cylinder : Typically manufactured using a winding process, primarily circumferential winding, to provide circumferential strength against internal pressure. Axial strength is provided by the superposition effect of multiple layers of cross-winding or circumferential winding. Heads : Typically elliptical or dished heads . This streamlined design facilitates stress distribution and provides significantly better pressure resistance than flat heads. Heads are mostly produced by hand lay-up or compression molding. Support system : This is one of the most critical components of a horizontal storage tank. Saddle bearing : the most commonly used type of support, usually consisting of two bearings. Fixed end support : One of the support has round bolt holes to secure it completely. Sliding end support : The anchor bolt holes of the other support are elongated holes, which allow the storage tank to expand and contract with temperature changes, preventing excessive thermal stress.

Fiberglass pressure tanks are among the most technologically advanced and demanding fiberglass products in terms of design and manufacturing requirements. They must not only withstand the weight of the medium under static conditions but also operate safely under internal pressure. Using fiber-reinforced plastic (FRP) as the primary material, they are sealed containers used for storing or handling pressurized fluids (gases, liquids). Their design and manufacturing must adhere to stringent pressure vessel standards (such as ASME X, NB/T 47012). Manufacturing Process  Fixed-length winding is the most important and advanced process for manufacturing fiberglass pressure vessels. Process: Under the control of a computer numerical control (CNC) system, continuous resin-impregnated fibers are precisely wound onto a rotating mandrel according to a preset line shape and thickness, followed by curing and demolding. Core Features: High specific strength: Lightweight yet with high pressure resistance. Excellent corrosion resistance: Resistant to various chemical media such as acids, alkalis, and salts, eliminating the need for linings and anti-corrosion coatings.

Quartz sand as a reinforcing material into the structural layer, based on FRP wound pipes . Their structure typically consists of: an inner lining (resin- rich layer for corrosion and seepage prevention) → a structural layer (glass fiber for strength) → a sand-filled layer (resin + quartz sand for rigidity and cost reduction) → an outer protective layer (anti-aging and anti- corrosion). Characteristics of FRP Mortar Pipe The design of fiberglass reinforced plastic (FRP) sand-filled pipes cleverly combines the advantages of multiple materials, giving them the following outstanding characteristics: 1. Extremely high stiffness and resistance to external pressure Core Purpose : The main function of the sand-filled layer is to significantly improve the ring stiffness of the pipeline . After the quartz sand is mixed with resin, a hard "composite mortar" layer is formed, which enables the pipeline to effectively resist the huge external pressure of soil load, ground live load (such as vehicles) and groundwater, preventing the pipeline from deforming and flattening. High design flexibility : By adjusting the thickness of the sand layer, FRP Mortar Pipes with different stiffness grades (such as SN5000, SN10000) can be flexibly produced to meet the requirements of different burial depths and geological conditions. 2. Excellent corrosion resistance FRP Pipe inherits all the corrosion-resistant advantages of fiberglass pipes. The inner lining consists of a high resin content and a surface felt, providing an excellent barrier against corrosion and seepage.

FRP Continuous Winding Pipe is a composite pipe manufactured using a continuous winding process. Compared to fixed-length wound pipe: Characteristic Continuous Winding Pipe Fixed-Length Wound Pipe Production Process Continuous, of arbitrary length Produced individually, with a fixed length (usually ≤12m). Production Efficiency Extremely high efficiency , suitable for large-scale standardized production. medium Pipe Diameter Range Typically medium diameter (DN200-DN2400) The widest range (from small to very large caliber) Length Length unlimited , reduce joints Fixed length, multiple joints Inner Surface Very smooth smooth Structural Features No longitudinal seams, high circumferential strength There are longitudinal and circumferential seams Main Advantages High efficiency, low cost, and unlimited length Highly flexible and capable of producing irregularly shaped parts

HFL3528A One-Way Pressed Outer Ring Needle Roller Bearing is a compact transmission bearing. Model number: HFL3528A Size: 35x42x28 mm Weight: 0.055 KG MOQ: 50pcs The HFL3528A one way drawn cup needle roller bearing, also known as a needle roller clutch, is designed for reliable one-direction rotation in compact mechanical systems. With a drawn cup outer ring made of ST14 steel and precision GCr15 chrome steel rollers, this model ensures high strength, minimal radial space, and smooth locking performance. Structural Features:  Belongs to the HFL series, consisting of a stamped outer ring, plastic cage, needle rollers, and spring plates. The cage can be configured with plastic or stainless steel spring plates to guide the needle rollers. The inclined raceway on the outer ring, together with the needle rollers, forms a locking mechanism to achieve unidirectional transmission functionality. Support bearings are installed on both sides of the needle clutch to bear radial loads. These support bearings consist of needle and plastic cage assemblies. The absence of an inner ring design results in relatively higher shaft wear, typically requiring shaft hardness to reach HRC 58-62.
