API 5L Seamless Pipe are used in conveying water, oil and gas. API 5L ERW Pipe are also suitable to use in natural gas, oil refineries and water supply systems. There are two different product specification levels PSL1 and PSL2 of API 5L Pipe that have different composition and mechanical properties.
The steel line pipe material generally in carbon steel and comply to API SPEC 5L specifications. Applied for petroleum and natural gas industries, oil industries requirements for transportation and are expected working in extreme situations, low and high temperatures, corrosion resistance for corrosive environments, and for sour services in H2S API 5L pipe specifications American Piping Products
Carbon steel pipe is used as the base pipe of bimetallic combination tubing, which has an internal liner made of stainless steel, titanium alloy steel, copper or aluminum, and so on. This type of tubing has high mechanical performance, high corrosion resistance, high weldability, high operational convenience, and high safety. Newest Press Releases, Hunan Standard Steel CO.Hunan Standard Steel Co. is as the one of member of Husteel Industry Group, as the professional manufacturer of steel pipe and pipe fittings,which has a complete system of production and sales serving our customers.

Since normalizing the heating temperature (hypoeutectoid steel as Ac3 +30 ~ 50 °C, eutectoid steel is Accm +30 ~ 50 °C) temperature control than hot-rolled termination strict, so the organization of steel, uniform performance.
Mar 29, 2019 · Precision spiral steel pipe is a kind of high-precision steel pipe after cold drawing or hot rolling. Because the inner and outer walls of precision spiral steel pipe have no oxide layer precision spiral steel pipe, high pressure and no leakage, high precision, high smoothness, no cold deformation, flaring, flattening without cracks, etc., it is mainly used to produce pneumatic Sturdy, Stainless cold rolled spiral steel pipe for The cold rolled spiral steel pipe you can find on the site are generally built using hot-dipped technology to prevent rusting and weakening of the structural elements. With seamless welding quality, these cold rolled spiral steel pipe are annealed with nitrogen protection and are polished with utter professionalism. These products are made of
After testing, all Lone Star ERW pipe is full body normalized by passing through a battery of induction furnaces where it is heated to temperatures above 1,650° F. It is then hot reduced to size, cut to ordered length and air-cooled. After cooling, every pipe is straightened, visually inspected, stenciled with the appro- The API Steel Pipe Normalizing Heat TreatmentApr 26, 2017 · It has been proven that as normalizing involves heating above eight hundred degrees in order to promote the API steel pipe base metal grain refinement, this will change the original characteristics of the API steel pipe as piping structure since the effect of the API steel pipe normalizing heat treatment on the metal micro structure has not been yet well studied in
Weled steel pipe specification, Standard and identification. Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. Top Seamless Carbon Steel Pipe Manufacturer and SupplierCompared with alloy steel pipe, It has the advantage of good performance with lower cost. Agico supplies most often used carbon steel pipes and tubes of comprehensive grades and specifications. According to its production process, Including seamless steel pipe , erw steel pipe and spiral welded steel pipe .
The spiral steel pipe pile has a steel pipe (3), a spiral portion (4) gained by twisting flat steel having the same or a greater width than the outer diameter of the steel pipe, and a spiral slit (5) through which the spiral portion is inserted at the lower end of the steel pipe, and is characterized in that the spiral portion is inserted into What Is Normalizing? Metal Supermarkets - Steel Jan 24, 2019 · Normalizing is a heat treatment process that is used to make a metal more ductile and tough after it has been subjected to thermal or mechanical hardening processes. Normalizing involves heating a material to an elevated temperature and then allowing it to cool back to room temperature by exposing it to room temperature air after it is heated.
Jul 21, 2014 · Normalizing permits the refinement of a metal's grain size and improves the metal's mechanical properties. Normalizing gives steel a uniform and fine-grained structure. This uniformity in the chemical and physical properties of an alloy is most important after it has been casted, forged, hot rolled or cold rolled.Heat Treatment Of Steel -Tempering, Hardening, Jul 27, 2019 · Afterward, the metal is slow-cooled. Normalizing:- Normalizing involves heating steel, and then keeping it at that temperature for a period of time, and then cooling it in air. The resulting microstructure is a mixture of ferrite and cementite which has a higher strength and hardness, but lower ductility.
