The corresponding categories are thin steel plate, stainless steel plate, aluminum plate, plastic and glass fiber reinforced plastic. Following, in accordance with the instructions in order, followed by instructions.The first chapter of the production and installation of steel sheet gout pipelineFirst, this chapter includes galvanized steel duct, ordinary steel duct, galvanized steel pipe (no flange connection), fan coil bracket accessories, connecting pipe, ventilation pipe production installation and flexible hose installation, a total of seven 30 items.
Q:What is the meaning of flange PL50-16RF
Flange, nominal diameter 50mm, voltage 1.6MPa, convex seal type.Flange generally referred to as flat, also called a welding flange. Connecting flange and pipe is the first tube inserted into the flange hole to a proper position, then take welding.
Q:What is the SO flange?
SEO hubbed flange see below: welding flange diameter steel tube inserted in. The part of the weld where the flange protrudes. Here is the sealing surface
Q:What is a stone flange?
Anti leakage: stitching seamless, smooth and smooth interface. Easy renewal: any serious damage such as burn marks, stains and cutting marks can also be restored by grinding procedures, so that the surface is as smooth as new. Yi Qingjie: solid, surface, wood, pores, dirt can be cleaned with soap, water or detergent.

Q:Flange WN50 (B) -25 RF S=6 specific points
WN indicates that butt welding 50 means nominal diameter DN (B means B series diameter is 57) - 25 is pressure, new standard is 25 kg pressure, old standard is 250 kg pressure RF, sealing surface protrusion S=6 flange diameter thickness is pipe thickness
Q:What are the advantages of a flanged plunger valve?
Advantages of flanged plunger valves:In 1, the flange valve in the plunger and the seal ring used between the interference fit, by adjusting the gland in the flange bolts, the lateral force and the valve body sealing ring compression product in cylindrical hole surface and the plunger seal, thus ensuring the sealing performance of the valve, to prevent the internal leakage, and valve opening moments small, can realize the rapid opening and closing the valve;2, because the sealing ring adopts the strong rebound resistance and the abrasion resistance of the non-toxic new sealing material, has a long-term high temperature, high pressure without losing elasticity, so the sealing performance is reliable and durable.Extension of knowledge point:Flange plunger valve by the valve body, valve cover, stem, plunger, hole frame, ring, hand wheel and other components. When the hand wheel rotates, the plunger is driven to move up and down in the middle of the hole frame through the valve stem to complete the opening and closing function of the valve. Currently, flanged valves are widely used in petroleum, chemical, chemical, gas, gas, liquefied petroleum gas, HVAC and general industries
Q:What is the waterline of flanges?
Its function is to form labyrinth seals when flanges are connected to reduce leakage of gas or liquid!Prepare a chart, but not.
