Tongue And Groove Face Flanges
The Tongue and Groove faces of this flanges must be matched. One flange face has a raised ring (Tongue) machined onto the flange face while the mating flange has a matching depression (Groove) machined into it's face.
Tongue-and-groove facings are standardized in both large and small types. They differ from male-and-female in that the inside diameters of the tongue-and-groove do not extend into the flange base, thus retaining the gasket on its inner and outer diameter. These are commonly found on pump covers and Valve Bonnets.
Tongue-and-groove joints also have an advantage in that they are self-aligning and act as a reservoir for the adhesive. The scarf joint keeps the axis of loading in line with the joint and does not require a major machining operation.
General flange faces such as the RTJ, TandG and the FandM shall never be bolted together. The reason for this is that the contact surfaces do not match and there is no gasket that has one type on one side and another type on the other side.

Statistics show that the increase in the output of plastic products has led to an increase in sales of plastic machinery. The good development prospect of the plastics processing industry will continue to be the main driving force for the rapid development of China's plastics industry. After joining the WTO, China's plastics machinery industry has brought at least two favorable conditions for development: First, it is conducive to exports; Second, it is conducive to the introduction of technology, including foreign advanced manufacturing technology brought by joint ventures and sole proprietorship enterprises in China.
China is the world's largest producer of plastics machinery, but its export value has only accounted for 5% to l0% of its total sales value for many years. This is incommensurate with the fact that big machinery countries such as Italy account for about 50% of their total output value. . According to China's current production capacity of plastic machinery and export potential, increasing exports should be one of our basic developments for further development. We must make full use of the opportunities brought by China's accession to the WTO, strive to create conditions, increase exports, and expand the space for the development of China's plastics machinery industry.
The rapid development of plastic packaging machines in the traditional machinery industry
China's plastic machinery has become one of the most rapidly developing industries in the traditional machinery manufacturing industry. The annual demand has increased. The rapid development of China's plastics machinery industry is due to the following factors: First, the rapid development of the domestic plastics processing industry, the strong demand for plastic machinery; Second, the demand for high-tech equipment brought about by the equipment update and outdated equipment.
