LSAW Steel Pipe

Project Location: Mongolia Usage: For Drinking Water Pipeline Transmission Arrival time：2023.12 Product：Black&Galvanized Pipes, Fittings and Couplings Specification：1/2 inch–10 inch Standard and Material： ASTM A53, ASTM A234 WPB With the continuous development of globalization and increasingly frequent international trade cooperation, the number of Xinyue Company’s orders has increased multiple times. On the one hand, it benefits from the concerted efforts of the Xinyue team, and on the other hand, it also benefits from the trust and support of our customers. Today I would like to introduce to you a Turkish customer who has been undertaking the construction business of international projects. In 2022, he took over Mongolia’s drinking water transmission project. Based on our good cooperation in the past, the customer has unswervingly chosen to order products from Xinyue since the beginning of this project, and has continued to place new orders based on the progress o...

　　 Galvanized pipe is pipe that has been coated with a layer of zinc. This coating protects the pipe from corrosion and rust, leading to increased longevity and enhanced reliability. 　　The zinc is often applied via a hot-dipping process, literally lowering the intended material—whether it is steel, aluminum or another metal—into hot zinc. This coating protects the pipe by corroding first when the pipe is out in the field, allowing the metal underneath it to stay intact and usable for a longer period of time. 　　Here are a handful of great reasons why you should choose galvanized pipes: 　　 Inexpensive Protection 　　Galvanization is often less expensive than other ways of protecting metal from corrosion. This is due to the fact that other methods often require intensive labor. Labor costs have risen steadily, which means the costs of these methods have risen as well. 　 　ASTM Galvanized Pipe Standardization 　　The ASTM has standards for many different types of galvanized pipes. ...

　　 Galvanized pipe coating process 　　A continuous galvanized pipe coating production technology and equipment, and the process includes the following steps: passivation, cleaning; paint; curing, with drying preheating before coating, and the drying preheating temperature is about ±20 ℃ of the curing temperature. The device is based on the known device, before the dip-coating slot with drying preheating furnace. The process and equipment can not only in bulk for continuous galvanized pipe paint production, but also ensure the quality of paint, the surface no bubbles, no orange peel, efficiency can be improved twenty or thirty times. 　　Hot dip galvanizing production difficulty is steel leakage defect, zinc layer falls off and edge thick. 　 　1. Steel leakage defect 　　In order to reduce cost and increase the strength of steel, much more silicon are often be added to the steel base. The exceeded silicon can increase the surface tension, reduce the steel plate to the zinc liquid wet...

　　 Galvanized pipe is usually used for indoor water supply. Outdoor water supply pipes are usually laid at <0.7m depth and must be below the local freezing line. Working pressure <0.6MPa. 　　Installation requirements of galvanized water pipe: 　　(1) The pipes, fittings and connecting methods for pipelines, pipe fittings and connecting pipelines for firefighting and domestic water sharing must comply with the design requirements or the construction specifications; pipes and pipe fittings shall be galvanized with all pipe walls and shall not be non-galvanized or galvanized only, Galvanized inside the pipe, pipe fittings used in domestic water supply pipe. 　　(2) Where the galvanized pipe used for water supply is connected with the pipe fittings, it shall be connected by means of threaded fasteners and welded connections shall not be used. Otherwise, the galvanized layer will be damaged or the inner diameter of the small pipe will be blocked by the welding torch. 　　(3) Prior t...

　　The diameter of steel pipe can be divided into outer diameter, inner diameter and nominal diameter. 　　The outer diameter of the pipe with the antiseptic spiral steel pipe is denoted by letter D, followed by the size and wall thickness of the outer diameter. 　　For example, the anticorrosive spiral steel pipe with an outer diameter of 108 has a wall thickness of 5mm, which is expressed by D108*5. The plastic pipe is also expressed by the outer diameter, such as De63. Others such as reinforced concrete pipes, cast iron pipes, and galvanized pipes are indicated by DN. Design drawings are generally expressed in terms of nominal diameters. The nominal diameter is a standard that is conveniently and artificially specified for design, manufacture and maintenance. It is also a nominal diameter and is the specification name of a pipe (or pipe fitting). 　　The nominal diameter of the pipe is not equal to its inner diameter and outer diameter. 　　For example: a nominal diameter of 100MM sp...

　　Generally speaking, the welded steel pipes are divided into general welded pipe, galvanized welded pipe, oxygen welding tube, metric system welded tube, transformer tube, welding thin wall pipe and spiral welded pipe etc. 　　General welded pipe: General welded pipe adopts Q195A, Q215A and Q235A or mild steel as raw materials. It is used to transfer the low pressure fluid. In addition, the pipes need water pressure, bending and flattening test etc. Usually, it has some certain requirements on the surface quality. The length of delivery is often from 4 to 10mm. The specifications of welded pipe in nominal diameter are different from actual size. Depending on the wall thickness, welded pipe are also divided into common steel pipe and thicken steel pipe. 　　Galvanized welded pipe: In order to enhance the corrosion resistance, the general welded pipe is galvanized zinc as protective layer. Galvanized steel pipe has two types: hot dip galvanized pipe with thicken zinc layer and electrica...
