Introduction: Basic metal wound gaskets are made by stacking V-shaped or W-shaped stainless steel strips and non-metallic fillers, spiral winding, and spot welding at the beginning and end. They are generally made by winding stainless steel<304, 304L, 316, 316L, 321, Ta Mon400 Inconel>with asbestos (graphite, PTFE, mica, ceramic) strips using specialized equipment. Basic metal wound gaskets are produced according to the relevant metal wound gasket standard dimensions and requirements; Gigabyte provides a full range of multi standard basic metal wound gaskets; Our current production capacity is 150000 pieces per month; Use different material combinations according to different usage requirements.
Outstanding performance:
1. Suitable gasket forms can be replaced according to different usage parts;
2. Replace different steel strips and fillers according to the requirements of different media;
3. The metal wrapped gasket is easy to replace and install;
Features:
1. Insulation: Used as electrical insulation, sealing, and anti sticking materials
2. Operating temperature: -180 ℃ to+250 ℃.
3. Self lubrication: With the smallest friction coefficient among plastics, it is an ideal oil-free lubricating material.
4. Non flammability: The oxygen limit index is below 90.
5. Chemical corrosion resistance and weather resistance: except for molten alkali metals, polytetrafluoroethylene is almost not corroded by any chemical reagents. For example, when boiled in concentrated sulfuric acid, nitric acid, hydrochloric acid, or even aqua regia, their weight and properties remain unchanged, and they are almost insoluble in all solvents.
6. It has the lowest friction coefficient among all known solid materials, and polytetrafluoroethylene is exceptionally smooth, even surpassing ice.
Specification: 3mm to 200mm, standard length is 1 meter, customizable in various lengths (m)
Installation precautions:
1. The winding part of the basic metal wound gasket must be between the flange sealing surface, and the width of the winding part cannot be widened arbitrarily, which will inevitably affect the tightening force of the bolt and thus affect the sealing performance of the gasket. 2. It is best not to use basic metal wrap gaskets on concave convex flanges, as the welding points on the inner ring of the gasket are prone to open under the axial compression force of the flange, resulting in gasket failure. 3. Under harsh working conditions such as high temperature, cold or frequent alternation of cold and hot, large vibration, and strong corrosive media, it is best to install a reasonable material inner ring on the gasket used for flat flanges and convex flanges. 4. Low material gaskets should never be used to replace high material gaskets. Avoid gasket failure caused by material corrosion or other reasons.
1. Select gaskets based on operating conditions and flange sealing surface type. 2. It is recommended to choose products from production enterprises with sound and effective quality management systems, preferably those holding special equipment (pressure pipeline components) manufacturing licenses and valid type test reports. 3. Compression rate, rebound rate, and sealing performance are important performance indicators of sealing gaskets. Generally speaking, the higher the rebound rate, the better, while meeting the compression rate requirements; On the premise of meeting the rebound rate standard requirements, it is also better to have a higher compression rate test value. Products with good sealing performance, moderate compression rate, and maximum rebound rate should be selected. 4. The surface of the gasket body is not allowed to have scratches, gaps, unevenness, or rust defects that affect the sealing performance. The non-metallic strip on the surface of the gasket body should be evenly and appropriately raised above the metallic strip, and the interlayer texture should be clear, but the metallic strip should not be exposed. The solder joint spacing of graphite wrapped gaskets should be uniform and there should be no defects such as lack of fusion or over fusion. The surface of the reinforcing ring should not have defects such as burrs, unevenness, rust spots, etc. The distance between the upper and lower sealing surfaces of the gasket body and the upper and lower surfaces of the reinforcing ring should be equal. The reinforcing ring and the gasket body should be tightly fixed and not loose; The outer ring and gasket body should be kept in position and can be appropriately loosened.
