Product Description:

1、Structure of Stainless Steel Welded Pipe ASTM A249/A269; GB/T24593:

    Stainless steel Welded pipe is used in applications that require the pipe to have high anti-corrosive properties. Compared to steel and cast iron pipes, stainless steels are more flexible, durable and have a higher strength. They are very resistant to erosion-corrosion and can be formed and welded into various shapes and sizes. It is easily connected with various other piping systems and materials and is designed to withstand long life cycles.



2、Main Features of Stainless Steel Welded Pipe ASTM A249/A269; GB/T24593:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Good visual effect

•Reasonable price

Q:Water and electricity thin wall stainless steel tube 304 material delta 2 what does that mean?
High temperature resistance is also good, the general use of temperature limit is less than 650 degrees centigrade. 304 stainless steel has excellent stainless steel corrosion resistance and better intergranular corrosion resistance. Delta 2 indicates wall thickness of 2 mm
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:Can stainless steel water pipes be cooled and bent?
They are lighter in bending and torsional strength, and therefore are widely used in the manufacture of mechanical parts and engineering structures. It is also used to produce all kinds of conventional weapons, guns, shells and so on.
Q:Stainless steel and stainless steel pipe inside and outside polishing off, what is the difference?
The inside and outside polishing tubes are polished by the surface of the polished material, and they look like bright ones, just like the mirror surface. Mainly used in viscous liquid and gas moving equipment, such as printing and dyeing, pulp and other industries
Q:Stainless steel pipe pickling ratio
Usage: used for contaminant removal of various types of stainless steel parts, sheet metal surface and its equipment rust, oxide skin, after welding of yellow blue black spot welding, a silver white metal surface cleaning, and surface passivation, corrosion resistance of stainless steel.
Q:Stainless steel seamless steel tube, ordinary seamless steel pipe, which is good?
Stainless steel pipe in the nickel element is relatively high, nickel is pipe rust proof, wear-resistant, mainly corrosion-resistant. The strength of the steel pipe is generally related to the content of carbon in the pipe. The ordinary steel pipe is carbon steel pipe, and the compressive strength is generally better than that of the stainless steel tube.
Q:What are the connecting methods of stainless steel pipes for indoor water pipes?
Card convex features: easy installation, the connection is not deformed inside and outside, belong to live connection, easy maintenance. Scope of application: cold water system, pipe direct drinking water system, water treatment equipment system. The installation is more suitable, mainly taking into account the replacement of the sealing ring later, the hot water system should be avoided as far as possible. The advantage of the connection is that the installation is simple, convenient and easy to maintain, and the sealing ring in the pipe needs replacing when aging, and the utility model is relatively simple and convenient, and the nut can be replaced as long as the nut is unscrewed. The disadvantage is that the applicable situation is single, in the hot water system sealing ring aging is more prominent, higher cost. Concealed piping and hot water systems are generally not recommended.
Q:How can galvanized steel pipe to be connected with stainless steel pipe?
Welding flanges respectively, with flange connection, but galvanized pipe according to specifications, dynamic welding after two times galvanized,
Q:What is the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless steel tube is a kind of steel strip with hollow section and without seams.
Q:Stainless steel tube, also known as why tube
Use can be divided into oil well pipe (casing, tubing and drill pipe etc.), line pipe, boiler tube, mechanical structure, hydraulic prop pipe pipe, cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, oil cracking tube) and shipbuilding pipe etc.
