steel pipe

 Architecture and Construction Stainless steel first came to prominence in construction during the art-deco period. Famously, the upper portion of the Chrysler Building was constructed from stainless steel. Due to its strength, flexibility and resistance to corrosion, stainless steel is now commonly used in modern construction. It is used in the exterior cladding for large high impact buildings and can be seen in the interiors too in the form of handrails, counter tops, backsplashes and more. Stainless steel is easily welded, has an attractive finish and is low maintenance. Because of this, it is featured prominently in high-profile modern architecture including the Eurostar Terminal in London’s Waterloo Station, the Helix Bridge in Singapore, and the One World Trade Center in New York. The trend towards sustainable building also favors stainless steel, which is often comprised of 90% recycled metal. Stainless steel in a polished or grain finish can help bring natural light into th...

 Tianjin Xinyue received the customer's inquiry at the end of February. At the beginning, the customer required to make seamless steel pipe. After several communication, the customer finally decided to make straight welded pipe instead of seamless steel pipe. It’s fix length 3.05 meters, surface galvanized and tube ends was threaded. The thickness of galvanized is 45 microns. This steel tube is the first trial order of the customer for installing lamps. Straight seam welded pipe surface do galvanized tube and steel tube should be cut into 3.05 meters in length, the customer request strictly, in order to better control the length tolerance, need to cut pipe a a cut, but this will increase the processing cost, in order to meet the needs of customers and orders requirements, tianjin xinyue would like to reduce profits, to ensure that meet customer's technical requirements, so as to achieve the long-term friendly relations of cooperation. Every piece of steel pipe is strictly inspe...

 In march, Xinyue received the order from the old customer in South Africa. ERW gr. BN PSL2 . In this spring and blooming April, after the production test for one month.The delivery was completed! And has passed the strict test of SGS in batches, all the physical and chemical tests were up to the standard! It is a pipeline used for transporting aviation kerosene, the terminal has strict requirements on material quality, so it is necessary to issue the laboratory report certified by CNAS, and SGS is required to do the final inspection to witness the physical and chemical experiments.The experiment lasted 4 days . The test data are very satisfactory . All four items from different heat Numbers are passed at one time. The containers have been left China . we hope our customer can get good reputation from this project ! Xinyue is always returns customers with the best product quality and service, and strives for 100% customer satisfaction. Xinyue steel is your most reliable partner. We...

 There are three main methods of manufacturing tubing that lend their names to tubing classifications. Seamless steel tubes are produced through extrusion. Extruded tubes can be formed in a hot or cold process. Long sections of steel bar are forced through a die that blocks out the intended shape of the tube. As-welded or electric resistant welded (ERW). This method involves passing a rolled sheet of steel through two weld rollers. The weld rollers have a groove around their circumference, through which the steel roll passes. There is a contact at the roll seam that transmits electricity at a high enough current to weld the seam closed. The resulting weld is very small. Drawn-over-mandrel (DOM). A mandrel is a small piece of metal inserted into the tube to define a shape. It gives the tube extra support to prevent unwanted wrinkling during drawing. The tube is passed through a die that has a smaller diameter than the current tube size. As the tube is drawn, it shrinks to match the ...

 Stainless steel is a type of steel alloy containing a minimum of 10.5% chromium. Chromium imparts corrosion resistance to the metal. Corrosion resistance is achieved by creating a thin film of metal oxides that acts as protection against corrosive materials. A popular grade of stainless steel is stainless steel 316. Stainless steel 316 is generally composed of 16 – 18% chromium, 10 – 14% nickel, 2 – 3% molybdenum, and about 0.08% carbon. The added molybdenum makes this grade more corrosion resistant than the other types. Aside from those mentioned, other elements can be added to modify certain properties of the alloy. Stainless steel 316 is widely used in highly corrosive environments such as chemical plants, refineries, and marine equipment. Stainless steel 316L has a lower carbon content and is used in applications that subject the metal to risks of sensitization. The higher carbon variant is stainless steel 316H which offers greater thermal stability and creep resistance. Anoth...

 On the last day of 2019, we received a repeat order from an old customer in the Middle East. The customer has continuously cooperated with us to purchase steel pipes for 3 years. This contract is a five-year supply contract for the project of bridge construction. The customer will purchase about 500 tons per year under project demand continuously, and with a single specification of 762 * 9.53 * 10M. Xinyue people's maintenance of old customers has always been the top priority. Although we have been supplied this contract for 2 years, the technical team of Xinyue still pays attention to all technical requirements as before. From raw materials to production to shipment, all the details are carefully discussed on the Pre-production meeting. For the 762 OD pipe, the wall thickness of 9.53 is a critical value, which is very difficult to control. In order to ensure that the minimum thickness of the customer cannot be less than 9.5mm, according to production experience, we decided to ord...

 Xinyue Steel has always adhered the principle “ 100% QUALITY ASSURANCE”. Xinyue has strictly controlled step by step from raw material inspection, pipe production , on-line inspection, off-line inspection to make sure everything complied with the required standard and customer’s specified technical terms,then delivery to customer on time.

Cold-rolled seamless steel pipes are often of small diameter, and hot-rolled seamless steel pipes are often of large diameter. The accuracy of cold-rolled seamless steel pipe is higher than that of hot-rolled seamless steel pipe, and the price is also higher than that of hot-rolled seamless steel pipe. Cold drawn (rolled) tubes are divided into round tubes and special-shaped tubes. Advantages: Fast forming speed, high output, and damage the coating, can be made into a variety of cross-sectional forms to meet the needs of use conditions; cold rolling can cause large plastic deformation of steel, thereby improving the yield of steel point. Disadvantages: 1.Although there is no thermal plastic compression during the forming process, there are still residual stresses in the section, which will inevitably affect the overall and local buckling characteristics of the steel; 2. The style of cold-rolled steel is generally an open section, which makes the free torsional stiffness of the section ...
