304 seamless stainless steel pipe is widely used in chemical equipment
The 304 stainless steel tube is widely used as a relatively low chloride ion content in water. It is mainly used in chemical equipment, pipeline transportation acid, heat exchange tubes and other fresh water contact processing equipment. The high chlorine content may cause pitting and crevice corrosion of the 304 stainless steel tube to the 304 stainless steel tube because the limit is 100 ppm. If exposed to harsh environments, it is easy to form intergranular corrosion.
The main users of 304 continuous steel pipe are a heat exchanger plant, a boiler plant, a water treatment plant and a chemical plant. 304 stainless steel is a very common material, such as kitchen utensils, good, qualified 304 stainless steel is absolutely not corrosive at atmospheric pressure and high temperature, because it has been good for most calculations and inorganic acid, alkali solution in 304 stainless steel tube Corrosion resistance, not only corrosion resistance, but also good molding and hot and cold processing properties, can be used to manufacture deep-drawn, cold-drawn, stretch-formed parts, even extending at 180 ° C, the strength and shrinkage of the cross-section is Very good, because its low temperature performance is also very strong.
Some rusted equipment manufacturers, according to Chinese standards, not SUS304 stainless steel rust unqualified, high-pressure steam sterilizer and air corrosion stainless steel SUS304 material quality qualified, 304 stainless steel as high medical equipment should not rust and corrosion Pit, severely unqualified products. It can be concluded that the manufacturer is completely wrong because the 304 stainless steel tube is rusty and can only be in corrosive conditions.
The portable routing machine is an electric Power Tools with a rotary cutter which is designed for the chip-removing shaping of wood and other materials. It can be used for example for edge trimming, fitting and trimming work. The drive shaft carries a router bit with shank which is predominantly positioned at right angles to the guide surface.
