Q:What is a stone flange?

Acrylic stone real flange (composite) - kitchen table changes in the quality of life in modern society, more and more attention from the public health and environmental protection, green health can not be ignored as indexes into closely related with people's daily life in all kinds of materials, stone flange professional quality guarantee for modern people's needs on health life. Flange, acrylic, man-made stone professional brand. As an environmentally friendly surface material, the flange is safe and convenient, and the real acrylic can effectively prevent the aging of the surface of the table surface. The fine texture makes the bacteria unable to survive, sanitary and beautiful. It is a marble texture, and wood processing performance, as well as beyond the general decorative material plasticity, in the brand ranks of man-made stone ranks unique, it can be said to be decorative materials all-round player. (a) all ten - flange stone meet your environmental health standard Home Furnishing antibacterial: from bottom to surface solid body, no pores, not absorb water or bacteria, the use of safe and reliable without shelter evil people and countenance evil practices. No: solid surface material is composed of acrylic acid, minerals and natural color, do not distribute any gas at room temperature. Flammability: refractory materials are tested by China National Fire building material quality supervision and inspection center. Hygiene: meets the National Health Foundation (NSF) standard fifty-first items, suitable for cooking equipment materials and components, and can be in direct contact with food.

Q:What does the Rc-RF in the flange stand for? What do they stand for?

Q:What is the meaning of flange PL50-16RF

Flange, nominal diameter 50mm, voltage 1.6MPa, convex seal type.

Q:What is a flange? Where is it usually used?

Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".Reducer flange for motor and reducer connection, as well as reducer and other equipment between the connection.

Q:There are 32; 3, 11/2, and so on, please master pointing, by the way, such tagging is based on what standards.

This is the American Standard. "6" means "DN150 11/4", which refers to "DN32", "11/2", "DN40", "" and "DN80"

Q:How do you calculate the size of the flange? How many inches do you calculate? What's the inside diameter or what?

It's 3 inches.A 1 inch, 3 inch is equal to 25.4mm, 80mmTwo, flange diameter of 190 diameter 80 in diameter diameter corresponding to 80 mark, is 3 inches.Turn left and turn right |

Q:A metal pipe nominal diameter 1200, using flange connection. In the original installation technical requirement, "parallelism: tolerance is 1mm/1000mm". How do you measure parallelism? What does this "1mm/1000mm" mean? How do you explain that?Another: flange roughness and how to measure and explain??

The control problem, method of measurement of parallelism is the datum plane placed on the plate, with a dial indicator to measure the surface within a range of 1200 error value does not exceed 1.2 mm.Flatness, in mechanical drawings, shapes and positional tolerances, is popularly known as flatness, defined as the maximum variation of the measured plane and the ideal plane in the tolerance range. The flatness of the reference plane requires a higher level.If the flatness of the reference plane of the flange is strict, the parallelism can be checked with a vernier caliper.

Q:What is the output flange? What's the function?

Flange connection is the two pipes, pipe fittings or equipment, first fixed on a flange, between the two flanges, plus flange pad, bolted together, completed the connection. Some pipe fittings and equipment have their own flange, but also belong to flange connection.Flange, threaded connection (wire), flange and welding flange.

Not the same meaning. The six head bolts are hexagonal in shape, and there is a gasket like structure between the head of the flange bolt and the thread!

Q:there is a pair of flange drawings, the above mark is 6-M12 evenly distributed 23 drill 24, what is the specific meaning?

The 23 attack drill 24 means with drill out the light hole cylindrical surface depth of 24mm, and then use the screw thread tapping into the effective depth of 23mm, which uses standard gauge M12 can be screwed into the 23mm, however, it should be marked drawings of consultations, the final hole should have 1.5 to 2 times the pitch pitch (M12 is 1.75), is about 3mm of the margin, or even the best teacher is also very difficult to achieve. This is my old fashioned experience for reference.
