http://montymontgomeryart.com/bduydm08 Stainless steel in the past 20 years, the world’s stainless steel pipe production has developed greatly, technology and equipment levels have improved greatly, in recent years in the new and expanded stainless steel seamless pipe workshop, welded pipe workshop and cold rolling cold drawing workshop, there are many fruitful new technology and efficient new equipment. China’s stainless steel pipe production after more than 40 years of development, especially in the past 20 years, both stainless steel seamless pipe or welded pipe production technology has made great progress, production, quality and variety continue to increase and improve the quality of a few products to reach the international advanced level.

https://writersrebel.com/h5skmipl 1, according to the production method: seamless tube – cold-drawn tube, extruded tube, cold-rolled tube. Welded pipe: (a) classification by process – gas shielded welded pipe, electric arc welded pipe, resistance welded pipe (high frequency, low frequency). (b) according to the welding seam – straight seam welded pipe, spiral welded pipe.

https://www.sigmbi.org/9lfdixaq5 3, classified by wall thickness: thin-walled steel pipe, thick-walled steel pipe
https://wsbeorchids.org/2022/uvou16xwx 4, classified by use: civil tube: round, rectangular, flower tube, generally used for decoration, construction, structure, etc..
https://velvet-avocats.com/pja1appill Industrial pipe: industrial piping with steel pipe, general piping with steel pipe (drinking water pipe), mechanical construction / fluid transfer tube, boiler heat exchange tube, food sanitation tube, etc. Generally used in various fields of industry such as: petrochemical, paper, nuclear energy, food, beverage, pharmaceutical and other industries with high requirements for fluid media pipeline.

1, the concept of steel: steel is ingot, billet or steel through pressure processing into the various shapes, sizes and properties of the materials we need. Steel is an important material essential to national construction and the realization of the four, stainless steel pipe materialization is widely used, a wide variety, according to the different shapes of the section, steel is generally divided into four categories of profiles, plates, pipes and metal products, in order to facilitate the organization of steel production, order supply and good management, and is divided into heavy rail, light rail, large sections, medium-sized sections, small sections, steel cold-formed steel, steel. High-quality sections, wire rod, medium-thick steel plate, thin steel plate, electrical silicon steel sheet, strip steel, seamless stainless steel pipe steel, welded stainless steel pipe, metal products and other varieties.
Tramadol Cheap 2, steel production methods: most steel processing is steel through pressure processing, stainless steel tube materialization points to make the processed steel (billet, ingot, etc.) plastic deformation. According to the steel processing temperature steel is divided into two types of cold processing and hot processing.
https://wash.co.uk/nisxjw9vk3 The main processing methods of steel are: rolling – the steel metal billet through the gap between a pair of rotating rolls (various shapes), due to the compression of the rolls to reduce the cross-section of the material, the length of the pressure processing method to increase, which is the most common way of producing steel production, mainly used to produce steel profiles, plates, tubes. Divided into cold rolling and hot rolling.
https://velvet-avocats.com/k3n1es5n Forging steel: the use of forging hammer reciprocating impact or press pressure to change the billet into our desired shape and size of a pressure processing method. Generally divided into free forging and die forging, commonly used for the production of large materials, open billets and other cross-sectional steel size of larger materials.
https://10rate.com/gulsjkl7jf Pulling steel: is already rolled metal billet (type, tube, products, etc.) through the die hole pulling into a cross-sectional reduction in length increase processing methods mostly used for cold processing.
https://sepiabodoni-expo.com/m7nsyzrzs0m Extrusion: is the steel metal in the closed extrusion Jane, one end of the pressure, so that the metal from the specified die hole extrusion and get the same shape and size of the finished product processing methods, mostly used in the production of non-ferrous metal steel.

http://montymontgomeryart.com/libqe7e 1, seamless steel pipe stainless steel: seamless steel pipe is a long steel with a hollow cross-section, no seams around.

Characteristics of seamless steel pipe: From the above process we can easily see that, first, the thicker the wall thickness of the product, the more economical and practical it is, the thinner the wall thickness, its processing costs will rise significantly; second, the product’s process determines its limitations, the general seamless steel pipe low precision, uneven wall thickness, low brightness of the tube appearance, the high cost of sizing, and the internal and external appearance of the pockmarks, black spots are not easy to Third, its detection and shaping must be processed offline. Therefore, it reflects its superiority in high pressure, high strength, mechanical structure materials.
Tramadol Online Cash On Delivery The manufacturing process and process of welded steel pipe: steel plate > slitting > forming > solution jointing > induction bright heat treatment > internal and external welding channel treatment > shaping > sizing > eddy current detection > laser sizing > pickling > storage
https://writersrebel.com/yqz6wp8qrj Characteristics of welded steel pipe: From the above process flow we can easily see: one, the product is a continuous online production, the thicker the wall thickness, the larger the investment in the unit and dissolving equipment, the less economical and practical it is. The thinner the wall thickness, its input-output ratio will drop accordingly; secondly, the process of the product determines its advantages and disadvantages, general welded steel pipe with high precision, uniform wall thickness, high brightness of the tube appearance (the surface grade of the steel plate determines the surface brightness of the steel pipe), can be arbitrarily sized. Therefore, it reflects its economy and beauty in high-precision, low and medium pressure fluid applications.
