Q:DN200 how many screws are there in the weld flange?
For welding flange DN200, many customers say the welding flange you DN200, but you and our site is not the same, your welding flange is thicker than the US, and your site we screw holes to. First of all, let us explain to you the customer, the pressure of your piping design is incorrect at first.
Q:When the toilet is fitted with flanges, is the rubber side of the flange facing the floor or the toilet? The installation is more reasonable
The rubber side of the flange is toward the toilet, and this has to be done by the master of water and electricity, or by the people who sell the toilet. The flanges and the toilet do not have space, but it will take some time!In addition, after the toilet is loaded, all sides should be put on glass glue, to prevent leakage of dirty gas
Q:Do I need flanges for rubber joints?
Rubber soft fittings can not be used without flanges. There are two carbon steel flanges at both ends of the product,Some customers also need counter flanges. In this case, 4 flanges are required for a productGongyi Kin Kun water supply equipment factory produces rubber soft joints all year round
Q:SolidWorks 2012 border flange profile editor cannot drag boundary line 20 ahSolid
2 methods, the first step to select 1 line, second generation flange flange contours drag select Edit flange vertical edge contour add size constraints. complete2 first generate the side flange directly, modify the sketch below the edge flange, and add dimensional constraints
Q:What do you mean by flange?
According to the connected components can be divided into container flange and pipe flange. According to structure type, integral flange, loose flange and threaded flange. Integral flange are common flange and butt welding flange. Less rigid flange, suitable for pressure P is less than or equal to 4MPa occasion; also called high neck flange flange, rigidity, suitable for high pressure and high temperature conditions. The flange sealing surface of the three types: planar sealing surface for the pressure is not high, medium non-toxic occasions; uneven sealing surface, suitable for higher pressure situations; the sealing surface of the tenon, for Yu Yiran, explosive, toxic medium and high pressure the occasion. Gasket is a can produce made of plastic deformation, and has a certain strength of the material.
Q:Flange specification PL80-1.6RF
This is the standard method of marking flange, welding plate steel pipe flanges, standard number: HG20593-1997PL is the flange type code, is the type of welding means;
Q:Urgent! Flange tolerance: flatness, parallelism,? Twenty
Parallel degree should be marked that flange mounting flange gap when the maximum and minimum width difference, the difference is not too large, is on the corner of the bolt flange sealing, not partial, or in some places more pressure gasket, gasket in some places may be there virtual pressure, although it does not leak, long time might be have a problem,As for flatness, the surface finish of machined surface should be considered as the flange sealing surface can not be a flat surface, and must be opened with mortise or groove
Q:What's the flange? What is its structure and function?
I just learned this introduction on Monday. Flanges are a kind of discoid parts. They are the most common in pipe engineering. Flanges are used in pairs. In pipe engineering, flanges are used mainly for pipe connections. In the need to connect the pipe, all kinds of installation of a flange, low pressure pipe can use wire connection flange, more than 4 kilograms pressure use welding flange. Seal points between the two flanges, then fasten with bolts. Different pressure flanges have different thicknesses and use different bolts. 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. In the two plane in the vicinity of the use of bolted connections, and closed parts are generally referred to as "flange", such as ventilation pipe connection, this kind of parts can be called "flange parts."". 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".
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 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
