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
One of the rubber sides of the flange faces toward the toilet
Q:Inside and outside the plastic coated steel plastic composite pipe to flange connection
In a shell of an electron tube, there are more than two electrode systems, each of which is independent of the electron flow to achieve its respective functions. This tube is called a composite tube. A composite tube is a combination of two or more transistors in accordance with a certain law, which is equivalent to a triode, and the compound tube is also called a Darlington tube.Composite pipes are divided into two categories: one is an ordinary composite pipe, and the inner no protection circuit; the middle and small power composite pipes like 2W are mostly such; and another kind of internal protective circuit is such a kind of high-power composite pipe. The following table shows the main characteristic parameters of the silicon NPN type high-power composite tube.
Q:To set the price
I checked it on the InternetThere are several kinds of this one you say
Q:Where is the difference between the double flange limit expansion joint and the double flange transmission joint?
Double flange dowel joint can transfer the pressure thrust of the connecting piece (blind plate force) and error compensation line, reduce the damage of axial thrust of piping systems and equipment. Mainly used to connect the pump, valve, pipe and other accessories loose.I have a friend, Gongyi West Village Xin Xin pipe fittings factory production of these two products, you can consult, and I hope that my answer can help you
Q:What's the flange surface?
IF integral flange, SW socket welding flange, TH threaded flange; loose flange ring PJ/SE welding, PJ/RJ welding ring flanges; flanges BL, BL (S) lining flange
Q:WF face flangeI'd like to ask what flange form WF is,
written in WF flange?Supplement:1. flange connection points by welding, butt welding for (SO) (WN), socket welding (SW), (LJ), loose thread (PT).
Q:The soul of darkness, how about the souls on the slopes beside the cursed frogs outside 3 flanges?
4. magic, bow and arrow can only serve as an auxiliary, can not serve as the main force. 5. opening gifts suggest choosing a flame metamorphic gem, the early game (Wangcheng, outer walls and undead streets), 80%-90%'s enemies, weak fire. 6. sword God and God was badly cut chicken. Case: a main broadcast take the sword in the tomb of the dungeon play skeletons, a multi segment, the first under a huge damage, directly to the skull behind the play apart, waving empty, only the skeleton together again. Look at the real egg pain, case two: the 2 generation, giant sword and big chicken legs, when the enemy moves, you can directly put the enemy lying prone. But in this seat, the little monster in the move when the giant sword shot, often against the chop. I suspect that the 3 generation has "hard and direct protection", which is a continuous attack on the same target, and the target will be continuously reduced, which is a bad news for the weapon. Think of the 3 generation of giant weapons compared to the 2 generation, moves and withdrawal are slow. 7. most BOSS do not have "routines" for opportunistic. For example, the 2 generation, many non DLC original BOSS, can be raised to shield the back of the stream, "Lai die", there are several UP with this habit against the three generation of BOSS and small soldier, the result of crazy suffering. Even the ordinary Knight mobs are in your shield around him, he will use a Shield Slam your shield, causing damage prevention, and anti kill!!! BOSS war, against the 2 generation of giant BOSS has a formula called "crotch person", the "best student change, otherwise it will crazy. More than 8. UP anchors said in an interview that the 3 generation of "anti - roll decisions" is the most difficult of all generations
Q:How did the magic baby get into the North Garden of the flange?
Flange City, west gate, and then go straight to the northeast.Go to 462.95 and continue to the northeast. This way, even if it's the garden entrance. Go in, just this way.Walk to 494.73, turn to the south, you will see a piece of different flowers.Find the coordinates of the plants you want and then collect them.
Q:What is the function of the flange stub?!
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.
Q:How many kinds of flanges are there?
1. The flange is divided into flange, flange, threaded flange, socket welding flange and loose flange according to connection.2. according to the form of flange sealing surfaceFlange in accordance with its form of sealing surface can be divided into flat, convex surface, concave convex surface, tongue and groove surface and ring connection surface. There are 4 standards in our current flanges: National Standard (GB/T), machinery industry standard (JB/T), Sinopec General Corporation Standard (SH) and chemical industry standard (HG). The standard of the sealing surface of the name is different, see the table below the name of the sealing surface.Table cover name contrastSealing surface nameNational standard(GB) chemical industry standards(HG) Sinopec General Corporation standards;(SH) machinery industry standards;(JB)Plane plane (FF) full plane (FF) whole plane (FF) -Convex surface (RF), convex surface (RF), convex surface (RF), convex surfaceConcave convex surface, concave convex surface (MF), concave convex surface (MFM), concave convex surface (MF), concave convex surfaceTongue and groove face, groove face (TG), tenon (TG), tenon (TG), tongue and groove faceRing connection surface, ring connection surface (RJ), ring connection surface (RJ), ring connection surface (RJ), ring connection surface
