ERW Steel Pipe

Project Location: Australia Product: LSAW steel pipe Specification: DN500 Standard & Grade: EN10219 S355JR Usage: Jetty piling construction Received the inquiry in Oct 2021. Signed the contract on May 2022 Estimated Shipping time: June, 2022 In last Oct, Xinyue received a new enquiry of LSAW steel pipes with Epoxy painting from our regular client for a small jetty piling construction to Australia. The enquiry is very complex, one OD pipe but with several different length and in total quantity only several piles & less than 50tons, also required heavy thickness Epoxy painting. After several months of bidding, design changes and price updates, the project finally made good progress in this February. The end user had verbally awarded the project to our client, but it still needs about several weeks to confirm the specific technical terms and contract details. Due to the chaos of global shipping in recent years, the congestion situation of various ports is very serious. As a result...

Project location：Morocco Product：Seamless Steel Pipe Standard and material：DIN 2440 ST 33.2，DIN 2448/1629 ST 37.0 Specifications：21.3-508mm Usage：Fire System Inquiry time：2022.02.18 Order time：2022.03.04 Shipping time：2022.05.27 Estimated arrival time：2022.07.27 After Chinese New Year Holiday, Xinyue received procurement demand from a regular customer in Africa for thin-walled seamless steel tubes, the thickness is on or below sch 30, with some items in galvanizing and threaded. After two week negotiation, we have reached an agreement of cooperation. The key point for the thin-walled seamless steel tubes is the control of thickness , NDT and damage during transportation and loading. Xinyue insists to load the container in the mill to make sure the pipes arrive in good conditions. All the pipes has been passed inspection currently and really delivery to the destination. https://www.xysteelpipe.com/thin-wall-steel-pipe-for-fire-fighting-set-sail-again-to-africa/

 The general application of thick-walled seamless tubes must do the corresponding anti-corrosion and anti-rust treatment work. The general anti-corrosion work is divided into three processes: 1. Anti-rust treatment of pipes. Before painting, the surface of the pipeline should be cleaned of oil, slag, rust, and zinc dust. The product quality standard is Sa2.5. 2. After the anti-rust treatment on the surface of the pipeline, apply topcoat, and the interval between them should not exceed 8 hours. When applying the topcoat, the base surface should be dry and the topcoat should be uniform, rounded and free of lumps and air bubbles. Both sides of the pipe shall not be brushed within the range of 150~250mm. 3. After the topcoat has dried and solidified, apply the paint and bundle the fiberglass cloth, and the interval between the topcoat and the paint should not exceed 24 hours. Cracking of thick-walled seamless steel tube: In the whole application process of thick-walled seamless steel t...

 The surface roughness of carbon steel pipe refers to the small spacing and the unevenness of small peaks and valleys on the machined surface. The distance (wave pitch) between the two wave crests or two wave troughs is very small (below 1mm), which belongs to the micro-geometric error. The smaller the surface roughness of the carbon steel pipe, the smoother the surface. The surface roughness of carbon steel pipe is generally formed by the processing method and other factors, such as the friction between the tool and the surface of the part during processing, the plastic deformation of the surface metal when the chips are separated, and the high-frequency vibration in the process system, etc. . Due to different processing methods and workpiece materials, the depth, density, shape and texture of marks left on the machined surface are different. Surface roughness is closely related to the matching properties, wear resistance, fatigue strength, contact stiffness, vibration and noise o...
