Instruments used in the food processing industry, such as Low price sanitary electromagnetic flowmeter supplier china, must meet strict regulatory requirements. Authorities such as FDA, 3-A, EHEDG and AWS have formulated equipment and process standards and regulations to minimize public health risks. For example, health risks during food production may be caused by bacteria accumulating in rough and inaccessible equipment areas, or by cross contamination of inedible substances and food.
When the equipment is manufactured according to industry standards such as 3-A or EHEDG, high quality standards must be adopted in the design, materials and manufacturing process of Low price sanitary electromagnetic flowmeter supplier china.
Welding of sanitary design joints
3-A Sanitary Standard describes the welding of connectors used for Low price sanitary electromagnetic flowmeter supplier china. Qualified welded joints used in food production must be firm, sealed, smooth, free of cracks and voids, and have a minimum of soot contamination, oxides or other foreign matter. For a variety of reasons, welds are used instead of backing joints, for example: geometry does not allow an alternative permanent connection method, requiring a smooth all metal transition between two metal parts.
Sanitary welding -- Quality framework of Low price sanitary electromagnetic flowmeter supplier china
In order to achieve welding quality consistency, in addition to appropriate materials and welding equipment, there must also be an appropriate quality framework. The framework includes personnel training, standardized verification and verification flow, improved inspection methods and continuous improvement. The requirements of this welding quality framework are standardized based on decades of experience in the industry. Therefore, standards similar to 3-A in Chengdu largely rely on the specifications formulated by the American Welding Society (AWS).
Hygienic requirements and pressure equipment standards for Low price sanitary electromagnetic flowmeter supplier china
In the food manufacturing industry, Low price sanitary electromagnetic flowmeter supplier china is usually part of the pressurization system. In addition to meeting sanitary requirements, pressure equipment standards must also be followed. Fortunately, the welding standards corresponding to sanitary applications and pressure equipment overlap to a large extent, so a single welding quality framework can be implemented to cover these two requirements.
Welding process of Low price sanitary electromagnetic flowmeter supplier china
There are many welding processes for Low price sanitary electromagnetic flowmeter supplier china, such as TIG, MIG and MAG, each with its own characteristics, advantages and disadvantages. The corresponding process can be selected according to the characteristics of the work, such as material type and thickness, accessibility, required speed, quality requirements, etc. Low price sanitary electromagnetic flowmeter supplier china usually adopts two processes. We use rail arc welding to weld the process connection to the flowmeter, which is a mechanized variant of welding. Then, we use the laser welding method to weld the capillary tube in the sensor. Hygienic electromagnetic flowmeter suppliers also use laser welding for some of our other parts. After these two processes, the welding quality level is quite high.
