Q:Stainless steel pipe drilling?
Stainless steel itself is not high hardness, but it is difficult to processing reasons:Because the stainless steel contains C element is low, hardness is not high, and not easy to deformation, plasticity is poor, this is the iron and steel organization grain concentration caused by. This allows the drill to increase its viscosity when drilling, and it is not easy to chip out. The drill is easy to burn at this time. Through the practice comparison, we know that the opening of 135 degree bit is much easier when the control speed is 300-500 to /min. It is much easier than the drilling of 118 degree hole on the same material.
Q:Ask experts, 304 stainless steel pipe why rust?
304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry.The common marking methods in the market are 06Cr19Ni10, SUS304, in which 06Cr19Ni10 is generally used to indicate standard production of the national standard. Generally speaking, ASTM standard production is indicated, and SUS 304 represents standard production.304 is a versatile stainless steel which is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium, more than 8% of the nickel content. 304 stainless steel is a brand of stainless steel produced according to the ASTM standard in the United states.
Q:Why can stainless steel pipes be welded by argon arc welding?
Argon arc welding arc welding, convenient operation and observation; electrode loss is small, easy to maintain the arc length, welding flux free, coating layer, so it is easy to realize mechanization and automation; argon arc welding welding can almost all metals, especially some refractory metal, oxidizable metals, such as magnesium, titanium, molybdenum zirconium and aluminum and its alloys; by the welding location restrictions, can be used for all position welding.
Q:What does "stainless steel pipe" DN mean?
In order to connect the pipe and pipe fittings in a unified way, nominal diameter (also called nominal diameter, nominal diameter) is adopted. For example, welded steel pipes can be divided into thin wall steel pipes, ordinary steel pipes and thickened steel pipes according to their thickness. Its nominal diameter is neither external diameter nor internal diameter, but a nominal size similar to the diameter of the ordinary steel pipe. Each nominal diameter corresponds to an outer diameter, and the inner diameter varies with the thickness. Nominal diameter can be expressed in metric mm, also available in English in. With nominal diameter pipeline accessories, meaning with tube.
Q:About stainless steel welding deformation
In fact, the deformation of stainless steel and carbon steel caused little difference, but the deformation is greater than carbon steel, the treatment method is the same.(1) using smaller welding rod and smaller current.(2) correcting welding sequence;(3) before welding, clamp the weldment to avoid warping.(4) avoid excessive cooling or preheating of base metal.(5) the welding penetration is low.(6) reduce weld gap and reduce slotting degree.(7) pay attention to the welding size, not to make the welding bead too big.(8) pay attention to the fixed measures to prevent deformation.
Q:304 stainless steel will rust it?
Stainless steel has the ability to resist atmospheric oxidation - that is, stainless steel, and also has the ability to corrode in medium containing acids, alkalis, and salts - that is, corrosion resistance. But its corrosion resistance is changed with the chemical composition, the mutual state, the condition of use and the type of environmental medium. Such as the 304 steel pipe, in the dry clean atmosphere, have absolutely excellent anti-corrosion ability, but it will be moved to the beach area, with large amounts of sea salt fog, will rust quickly; and the good performance of 316 steel pipe. Therefore, it is not any kind of stainless steel, capable of corrosion and rust in any environment.
Q:Comparison of ring type connection and argon arc welding of stainless steel pipe
1. The pipe is embedded in the pipe, and the ring pressure connection strength is high;2. After the ring is pressed, the inserted part of the pipe and the pipe is a closed ring, which can not generate spiral loosening and strong vibration resistance;3. The sealing material fills the entire seal cavity tightly and the seal is very reliable;4. Easy to install and quick.5. Shrinkage and anti drawing test of ring seal joint
Q:In stainless steel tubes, why are there some SS in the back and some standard L, such as 316L and 316SS? What's the difference?
316SS carbon content is higher than 316L (with L indicating ultra low carbon, corrosion resistance of chloride ion, improve its resistance to intergranular corrosion and oxide stress corrosion resistance), mechanical properties,.316SS strength higher than 316L316L is the steel that continues to reduce carbon content on the basis of 316316L is more resistant to corrosion due to its low carbon content
Q:The difference between galvanized steel pipe and stainless steel pipe
Plastic pipe, plastic pipe, also known as plastic composite pipe, with steel pipes for the matrix, by spraying, rolling, leaching, absorption process in steel tube (bottom tube) steel plastic composite pipe internal surface is welded with a layer of plastic coating or plastic anti-corrosion layer on the inner surface and the outer surface of the weld. The plastic pipe has excellent corrosion resistance and small friction resistance. Delivery of epoxy resin coated steel pipe is suitable for water, water, water, oil, gas and other medium, PVC plastic pipe for drainage, water, oil, gas and other media delivery.
Q:What are the specifications of stainless steel decorative pipes?
Decorative tubes, then more specifications. Our factory has the smallest 9.5MM, the largest to see how big you can, directly with the industrial pipe to polish it
