The biggest difference between seamless steel pipe and other long strips is that there is no joint around it, and the section of steel pipe is hollow. Due to different cross-sectional shapes, it is often classified as circular steel pipe and heterosexual steel pipe. Of course, circular steel pipe is more common in terms of actual use efficiency. Wonder…
Read MoreThere are many kinds of quality inspection methods for large-diameter seamless pipes, and physical methods are also the most common inspection methods. Physical inspection is a method of using some physical changes to carry out measurement or inspection. The inspection of the internal defects of raw materials or large-diameter seamless steel pipes is generally carried out by non-destructive testing….
Read MoreThe basic manufacturing process of thick wall P22 seamless alloy pipe is: melting, blank making, extrusion and annealing heat treatment. (1) Smelting P91 steel has high alloy content. How to complete the alloying of steel in a short time is the key of smelting process. P22 seamless alloy pipe is smelted by 50t power electric arc furnace + 5T…
Read MoreDefinition of carbon steel seamless steel pipe: carbon steel seamless steel pipe is a kind of long steel with hollow section, which is widely used as pipeline for conveying fluid, such as pipeline for conveying water, natural gas, oil, gas and some solid materials. Compared with solid steel such as round steel, steel pipe has the same flexural and…
Read MoreAlloy seamless pipe is a pearlite heat-resistant alloy structural steel, which has good high-temperature mechanical properties, high plasticity during cold deformation, no tempering brittleness tendency, good machinability and acceptable weldability. It is generally used under high-temperature normalizing and high-temperature tempering; It is mainly used for superheater tubes with working temperature of 570 ~ 585 ℃ in pressure boiler, pipeline…
Read MoreWhat are the processing methods of stainless steel welded pipe? What should be paid attention to in processing? Cold drawing deep processing: it is easy to generate friction heat, so the stainless steel pipe with high pressure resistance and heat resistance shall be formed at the same time. After processing, the oil attached to the surface shall be removed….
Read MoreAlloy steel pipes can be used to transport different substances, mainly including the following: 1. Transportation of solid particles and powders – anti-wear, impact resistance, self lubrication, anti adhesion, sanitation and cleanliness, impact absorption, good silencing effect, good resistance to environmental stress cracking, light weight, which can be applied to various industries, such as anti-wear transportation of solid particles…
Read MoreStainless steel welded pipes processing is easy to cause certain changes to the inside or outside of stainless steel welded pipes. Stainless steel welded pipe welding: Before processing and welding stainless steel welded pipes, rust, oil, water, paint, etc. that are harmful to welding should be thoroughly removed, and an electrode suitable for the steel grade should be selected….
