In the production process of tea drinks, flange connections of core equipment such as material conveying pipelines, sterilization equipment, and mixing tanks require the use of sealing products with good sealing performance, corrosion resistance, and resistance to aging. Ordinary seals may affect the quality and production safety of beverages due to unstable materials and other issues. The metal ring gaskets produced by Huahai Seals include octagonal gaskets and elliptical gaskets, with a cross-section designed as a regular octagonal or elliptical shape, specifically designed to match flange sealing grooves. After installation, they can form a hard seal contact between metal and metal. By precision forging and machining, the tolerance of the sealing surface is controlled within the relevant standard requirements, so that the gasket can tightly fit with the flange groove during installation and pre tightening, establishing a reliable initial seal.
In terms of material selection, the tea industry has clear hygiene requirements for seals. Huahai Seals can provide a variety of sealing products made of different materials, among which stainless steel material, due to the addition of alloy elements, has good resistance to acidic media, cleaning agents, etc. that may come into contact with tea processing, and is suitable for flange connections in tea equipment. For occasions that require non-metallic sealing, food grade polytetrafluoroethylene (PTFE) can be applied to sealing parts in indirect contact with materials due to its chemical inertness, non stick properties, and high and low temperature resistance. Under the sealing requirements that cannot be met by metal ring gaskets, enterprises can recommend suitable material solutions based on specific working conditions. Enterprises can provide a variety of sealing products made of different materials, which can be selected according to different working conditions of tea drinking equipment.
In the application scenario of tea drinking equipment, the flange connection should ensure no leakage or dead corners to avoid medium residue and microbial growth. The pipeline system of tea processing equipment requires frequent CIP online cleaning, and the reliability of flange sealing directly affects the cleaning effect and product quality. Huahai seals pay attention to the surface quality of products, and the smoothness of the sealing surface of the tea beverage industry pipeline system directly affects the sealing effect and the risk of pollutant adhesion. The company adopts high-precision precision machining technology and multiple strict inspection processes to ensure the flatness and accuracy of the sealing surface. For application scenarios that come into indirect contact with materials, the product can meet the hygiene and safety requirements of the tea beverage industry through strict surface quality control.
In terms of quality control, Huahai Seals has established a full chain independent production capacity from raw material cutting to finished product delivery, with each link completed by independent equipment to ensure process consistency. The enterprise has passed the relevant quality management system certification and is equipped with advanced testing equipment such as CNC machine tools and spectrometers. The full process quality tracking system from raw material input to finished product output provides a basic guarantee for the reliable application of products in the tea beverage industry. In terms of product specifications, Huahai Seals can produce various specifications of metal ring gaskets, which can meet the matching needs of different projects of tea drinking equipment. For non-standard products, enterprises can customize processing according to customer drawings and provide sealing solutions. Wenzhou Huahai Seal Technology Co., Ltd. is providing reliable sanitary sealing services for storage tanks, sterilization equipment, CIP cleaning systems, and material conveying pipelines in the tea beverage industry with a relatively complete sealing technology system, from corrosion-resistant stainless steel materials to sanitary sealing structure selection, from metal hard sealing of octagonal gaskets to standardized quality control throughout the entire process.
