Fiberglass flange

Fiberglass flangeIn specific use, the reasonable flange structure form should be selected based on the stress distribution inside the flange, fully utilizing the designability and easy formability of fiberglass performance. Is it reasonable to use an equal wall thickness structure with the same thickness as the cylinder for the flange? A transition cone neck should be set between the flange ring and the cylinder, which can increase or decrease the wall thickness with increasing stress. The fiberglass molded flanges produced by Hebei Weiheng Fiberglass Co., Ltd. are produced using mechanical molding technology. The flange models and sizes are uniform and consistent, and the surface of the molded flange is smooth and free from burrs, and the inner wall is smooth and not prone to dirt accumulation, with low resistance.

commonly usedFiberglass flangeCommonly used for medium and low pressure pipelines and containers with a pressure not exceeding 3MPa, the main structural forms include integral flanges, adhesive flanges, and loose flanges. A reasonable flange structure should be selected based on the distribution of internal stress in the flange, fully utilizing the designability and ease of forming characteristics of fiberglass performance. Is it reasonable to use an equal wall thickness structure with the same thickness as the cylinder for the flange? A transition cone neck should be set between the flange ring and the cylinder, which can increase the wall thickness with increasing stress and decrease the wall thickness with decreasing stress. This can reduce the phenomenon of local stress concentration and excessive deformation caused by the unreasonable structure of the flange. From the perspective of molding technology, the use of hand pasting, molding and other processes to manufacture flanges has good performance.

Adhesive flange is formed by processing the flange ring and cylinder separately, and then bonding the two together. This structure is widely used and fully utilizes the advantages of easy molding of fiberglass. The mold is simple and easy to manufacture, making it suitable for manufacturing large diameter, small batch, and special-shaped fiberglass material flanges.

The manufacturing of container flanges and special-shaped pipeline flanges often adopts two methods: bonding the cylinder and flange ring, and turning the cylinder into a flange. Although these methods are simple and easy to implement, the flanges are all flat plates, and their structure and stress distribution are not coordinated, which can easily lead to stress concentration, strain concentration, microcracks, cracking, and other phenomena. Using online molds for processing to produce containers and special-shaped pipelines that are structurally sound and integral with flanges.
