Gayatri tubes always work with the aim of creating a sustainable SS 310 / 310S / 310H flanges to make it be used for a longer time without replacement. We as a manufacturer and supplier and making and providing it to the clients at various specifications, face types, sizes, dimensions, classes, standards. Also, it is made available to the clients at customized specifications according to their prerequisites.
SS 301/310S flanges can be used wherein the heat treating on rolling hearth furnace is offered. The furnaces are filled up of temperature recorders-controllers. After heat treatment is offered, SS 310 slip-on flanges become stronger. It too becomes subjected to the pickling. In cases, the demanded size of SS 301S threaded flanges mightn’t be acquired from the mill, so the cold operation process is used for acquiring the desirable size.
SS 310S weld neck flanges into the cold drawing process, are coated with soap/oxalic solutions. This solution in SS 310S blind flange proceeds in the form of a lubricant for reducing friction at the same time as cold drawing operation. In the cold drawing process, SS socket-weld flanges are drawn using the die plugs over the bench. However, the drawn-out SS 310S lap joint flanges thus become subjected to heat treatment, strengthening, cleaning and heat treatment.
SS 310H a series of proprietary grades is contended with a carbon maximum of 0.03% and is used for the specific corrosive atmosphere. SS 310H slip-on flanges are having a very good sturdiness and at cryogenic temperature as well. The high content of chromium increases the greater temperature properties and also provides it resistance to corrosion ability. SS Socketweld flanges are resisting oxidation and carburizing atmosphere. The high content of carbon makes SS 310H lap joint flanges sensitization and IGC susceptible after welding or get exposed to elevated temperature.
SS 310 / 310S / 310H flanges are tested for checking its greater strength and quality. Few tests done on it are namely IGC test, PMI test, toughness test, pitting resistance test. At the time of shipping, these flanges are packed in wooden boxes, carton boxes, wrapped using plastic sheets for safer shipping only.
