U type radiant tube by Qingdao Hexin Machinery Co.,Ltd.
U type radiant tube
Our company produces U type radiant tube has the characteristic of heat resistance, oxidation resistance, cost-effective, good product stability. Strictly control various processes of U type of radiation tube in the production, and establish the organization of the ISO9001 quality assurance system. To have the effectively protecting of impurities for the radiation tube in the packaging and transportation en. Win the trust of customers with high quality products and services. U type radiant tube is widely used in the continuous annealing furnace, galvanized wire horizontal annealing furnace and silicon steel heat treatment furnace, etc..
The U-tupe radiant tube are usually used for continuous annealing line and galvanizing line vertical annealing furnace, under the hydrogen nitrogen protective environment, Tube is provided by natural gas or coke oven gas combustion heat energy,and radiate the heat to workpiece through tube wall, By way of radiation heat transfer outside tube,and make the strip steel running at a constant speed heated to 900℃quickly from the normal temperature, and make annealing treatment to strip steel.straight pipe adopt centrifugal casting as casting, precision casting for the elbow,the material is high nickel chromium alloy cast steel, such as 2.4879，1.4852，ZG45Ni48Cr28W5Si2、MORE1、MORE2.
These can be with or without flanges, bellows, collars, and/or insulation already installed.
