Carbon steel flange storage and maintenance is very important. The usual engineering projects are carbon steel materials. The surface of the flange of carbon steel material is very prone to floating rust. The surface is not good for a long time. The storage of the flanges should not be placed on the road immediately. Put the road surface into some moisture-proof mats, then place the flanges neatly. Leave the carbon steel flange and the carbon steel flange in the middle. The channel not only has the effect of natural ventilation but also facilitates the delivery of carbon steel flanges.

Common problems in the installation of carbon steel flanges

(1) The tightening force of the carbon steel flange should be the same, and the shrinkage of the leather pad should be manipulated at 1/3 left.

(2) Different steel frame structure can ensure the matching between the vibration processing technology of the mold and the maintenance slag, so as to maintain the introduction of stainless steel pipe.

(3) Carbon steel flanges must have sufficient compressive strength and cannot be deformed when tightened. The carbon steel flange surface should be leveled and cleaned. Care should be taken to remove grease and rust during installation.

(4) The gasket should have excellent acid and alkali resistance and aging resistance, and its ductility and impact toughness. Installation should be based on the joints of different cross-sections and specifications, and placed properly.

(5) The rubber ring of the carbon steel flange and the requirements in all directions and relatively large directional, put into the convex groove body of the contract, the installation can not be distorted carelessly to carry out introspection, and the result and the rise of the mouth, it is necessary After the refining of the steel ladle, the inspection will be given to the upper side of the package inlet, and the long water part will be introduced into the middle tundish.

Stainless steel flanges are not prone to etch, crevice corrosion, rust, and are not easily damaged. The stainless steel plate is the first of the most resistant materials for engineering metal composites. Because the stainless steel plate has excellent corrosion resistance, it enables the structural member to permanently maintain the consistency of the architectural design. The stamping flange of the Cr-containing stainless steel plate also combines impact toughness and high ductility on the whole body, facilitating the production and processing of the components, and considering the necessity of the architect and the overall design staff. All metal materials are reflected in co2 in the air, producing an air oxide film on the surface.

Stainless steel plate flange ball valve connection

1. The flange connection is this detachable connection. There are several types of flange protrusions: plan-type protrusions, suitable for places with low working pressure and non-toxic materials; convex and concave convex surface, suitable for places with slightly higher working pressure; Flammable, explosive, hazardous materials and places with high working pressure. The form change of the flange surface also stipulates that the stainless steel ball valve oil passage plate has the characteristics of being able to work under the relative load.

2. The flange of the stainless steel plate flange ball valve has a flange, and the hole with the standard eye distance is drilled according to the required specifications. The joint end of the pipe is also welded with the same standard flange piece, and the anchor bolt makes the stainless steel. The flange of the ball valve is in close contact with the pipeline flange;

3. The gasket is sealed with gasket according to the load regulations. The gasket is placed in the middle of the flange surface of the two flanges. After the nut is tightened, the specific pressure on the surface of the gasket exceeds the required value to cause deformation, and the convex surface is unevenly covered, so that the connection is tight and watertight;
