1. In order to prevent eye to eye corrosion due to heating of flange cover, the welding current should not be too large, about 20% less than that of carbon steel electrode, the arc should not be too long, the interlayer should be cooled quickly, and the narrow weld bead is preferred. 2. The welding

A valve device for a Sanitary Fitting having at least two control elements which are movable relative to one another and on which at least two inlet channels and at least one control channel are formed is described. The control channel is configured for a communicating connection between at least one of the inlet channels

Flange connection is to fix two pipes, fittings or equipment on a flange separately, between the two flanges, plus flange pad, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection. Flange connection is an important connection mode in pipeline

National Day is approaching. This year marks the 70th anniversary of the founding of New China. Many friends have already planned where to travel. They are very excited, but safety comes first. Therefore, we must pay attention to travel safety. Next, I will share some precautions for traveling safety during the eleventh long vacation. 1.Before

Carbon steel flanges are generally adaptable and can be used in different fields, and the carbon steel flange produced by this method is pn≥2 to the pressure of oil and gas field. 5MPa long distance transmission pipeline, station yard and other insulating carbon steel flanges are used. Simply change the carbon steel flange to the

The weld form is different: the weld seam cannot be radiographic inspection, and the weld seam can be welded. The welded weld seam with slip on flange pipe and flange is a fillet weld, and the welding weld seam with neck weld neck flange and pipe is ring weld; the flat weld is a two-fillet weld, Butt-weld.

There are many kinds of pipe fittings, inductive has the following main types: Variable diameter pipe, refers to the tube end or a part of the diameter of the tube is reduced; A pipe fitting with a thickened wall means a change in the wall thickness along the length of the pipe; Changing the cross-section

Socket welding flange, socket flange is one end of the welding pipe with the other end with bolts connected flange. Socket Flange Sealing Surface form: Face (RF), bump surface (MFM), socket welding flange, socket flange is one end with the other end of the welding pipe with bolts connected flange. Sealing surface form of socket

The selection of flange material shall be determined according to the nature of the flange bearing load, stress state, stress size, working temperature, environmental medium, service life, requirements for conductive magnetic conduction, process function, material source and price. Stainless steel Flange According to the mechanical properties, stainless steel flanges can be divided into tensile flange,

Weld neck flanges including long weld neck flange, flange with neck butt welding face, neck weld neck flange product, etc. it is mainly suitable for Uffalan and pipe welding, its structure is reasonable, the strength and stiffness is larger, can withstand high temperature, high pressure and repeated bending and temperature fluctuations, and its sealing performance
