Metal wrapped gasket with metal wrapping

Metal wrap pads are made by wrapping metal strips with soft fillers. Metal wrap pads are classified as carbon steel wrap pads, 201 stainless steel wrap pads, 304 wrap pads, 316 wrap pads, etc. due to the different materials of their metal strips. Metal wrap pads are classified as graphite wrap pads, PTFE wrap pads, asbestos wrap pads, etc. due to their different fillers.Metal wrapped gasket with metal wrappingThe basic type is made by using standard high-quality SS304, SS316 (V-shaped or W-shaped) metal strips and other alloy materials to overlap and spiral wrap with flexible materials such as graphite, asbestos, polytetrafluoroethylene, asbestos free, etc., and fixing the metal strips with spot welding at the beginning and end.

Metal wrapped gasket with metal wrappingGasket type 1 A、 There are four forms of wrapped gasket: basic type, with inner ring type, with outer ring type, and with inner and outer ring type.

B、 Spiral wound gaskets for heat exchangers are generally divided into basic types and types with inner and outer rings.

2. Commonly used materials: A. Steel strip: 08 F、0Cr18Ni9(304)、0Cr18Ni9Ti、1Cr18Ni9Ti(321)、0Cr17Ni12、M02(316)、00Cr17Ni14M02(316L)

B、 Cold rolled steel plate for inner and outer rings: Outer ring: 0Cr13, oCr18Ni9 Inner ring: usually made of the same material as the steel strip or determined through negotiation.

C、 Non metallic tapes: flexible graphite, specially made asbestos, polytetrafluoroethylene, non asbestos paper.

Performance: High temperature resistance, high pressure resistance, corrosion resistance, with good compression and rebound rates.

Application: Pipes, valves, pumps, manholes, pressure vessels and other flange connections in petroleum, chemical, power, metallurgy, shipbuilding, papermaking, medicine and other industries

The sealing part of heat exchange equipment is an ideal static sealing material.

Metal wrapped gasket with metal wrappingProduct Model:XINHONG-FAProduct FeaturesFilled with flexible graphite, ceramic fibers, asbestos and non stone materials, as well as boxed stainless steel, tinplate, copper and metal plates, it is particularly suitable for use in high-temperature and high-pressure sealed parts of heat exchangers, pressure vessels, etc. It can effectively prevent the erosion of gaskets and disintegrating media, while also improving pressure resistance.

Product Application:Suitable for heat exchangers, gas pipelines, cast iron flanges, cylinder heads, boilers, and other containers.
During the installation process, the sealing gasket is usually pressed down to the initial thickness that has already been deformed30%Therefore, effectively sealing surface irregularities and overcoming small defects in the flange. By selecting different metals and fillers, it can be suitable for various media.

Metal wrap gasket is a comprehensive sealing flange gasket that is resistant to high temperature, high pressure, and corrosion. Due to its advantages such as wide applicability, good substitutability, and low price, it is widely used by manufacturers, such as power plants, refineries, coal yards, etc., and has become the * of pipe flange sealing gaskets.

There are many standards for the execution of metal wrap pads, basically using GBT4622, HGT20610, and HGT20631.

spiral wound gasketThe friction coefficient of the bridge is usually small, only between 2% and 5%. Therefore, even when facing a bridge weighing tens of thousands of tons, only a few hundred tons of pushing force are needed. Therefore, the pushing equipment is very simple. During the construction process, although there is wear and tear on the metal wrapped and entangled gaskets, overall, it still reduces the consumption of energy. Metal wrap gasket is a commonly used sealing gasket. There are various types of metal wrap gaskets on the market, and many customers do not know how to choose them during use. The friction load capacity of metal wrap gasket is the primary consideration for people. During the operation of these devices, the progress is easy to grasp, and the overall progress can be determined based on the size of the prefabrication site at the bridgehead. If the short section of 4-5 meters can be developed into a long section of several tens of meters, the progress can be greatly accelerated. There is no need to set up scaffolding in the bridge opening, and the metal wrapped entangled gasket will not be affected by the water flow and traffic under the bridge.

Metal wrapped gasket with metal wrappingHow to identify the quality after purchasing? A simple analysis can be made from the following perspectives: the average welding performance of metal wrap pads and the welding * 2. The second factor to consider is whether the sealing surface is flat, which needs to be perceived by hand; Thirdly, we need to use our hands because the toughness of the steel strip will be replaced by defective products by unscrupulous merchants. Therefore, we can open the gasket and inspect it to avoid being deceived by merchants.
