News tell us that egypt is a modest exporter of natural gas transported by seamless steel pipe, galvanized steel pipe and so on, both through shipments of liquefied natural gas by sea and via pipeline to neighboring israel, jordan, syria, and lebanon. What, s the situation for chinese, s lng use and transportation? China's pipeline gas is mainly shipped from the west to the country, while lng receiving stations are built on the sea due to the high cost of pipeline gas crossing the oceans and the ever-decreasing cost of shipping lng and the increasing demand for clean energy from the developed coastal economies in the prc. Lng in the past few years makes rapid development in china. No matter which kind of gas we need to be used for our daily life, there is no doubt that we cannot leave the pipes behind for its transportation function. For example, domestic imports of natural gas mainly come from three parallel pipelines (starting in 2009) across turkmenistan, kazakhstan and uzbekistan, with an annual capacity of 55 billion cubic meters and an annual supply of 12 billion cubic meters of shwe pipeline in myanmar (13 years operation). This data tells us that high quality steel pipe is needed here.
With the expansion of urbanization, there is no doubt that the requirement for various steel products, like the galvanized steel pipe would be increased among every kind of engineering project. Shopping for galvanized steel pipe from manufacturer would be increased too. Galvanized steel pipe, with steel grade q195, q215, q235, q345, s235jr, s275jr, stk400, stk500 in threewaysteel, is for size of 21.3 - 610mm out diameter. All pipes have been hot dipped in a zinc rich galvanizing process. Of course, there are three types of the galvanized steel pipe including pre-painted (zinc: 60-120g/m2); hot-dipped galvanized steel pipe (zinc: 120-500g/m2) and cold-dipped galvanized steel pipe (zinc:10-50g/m2). Why it is an option for customers galvanized pipes are a lower cost alternative to stainless steel to achieve rust free protection once they have the helper of the zinc. Of course, maintaining comparable strength with a durable surface coating would be good for the corrosion resistance.
Cooling bed is a key link in steel pipe production line for guarantee the final quality. So there is essential to have some basic knowledge for those types of cooling bed for seamless steel pipe in order to produce high quality product. Most of us would familiar with single chain cooling bed and double-stranded cooling bed, so there would ignore the introduction about these two types. And today the main core is the new chain cooling bed and stepping rack-type cooling bed. The new chain cooling bed No doubt that with the development of advanced technology, the new chain cooling bed has combined good feature of single and double cooling bed as well as other special characters which would good for the production of the steel pipes. New chain cooling bed has been divided into uphill and downhill. The positive and negative interaction make the steel pipe continue to rotate forward and do climbing which is good for quality. Downhill section for the forward transport chain and steel pipe parallel arrangement of single-chain structure, relying on self-weight to achieve rotation, so landslide movement. Stepping rack- type cooling bed With two sets of step racks, there is no doubt that we can make the steel pipes safely and high quality except the basic demand requirement for steel pipes.

HongKong-Zhuahai-Macao Bridge would be completed at the end of year 2017, according to recent news. Thanks to all of engineers as well as various materials like the steel products ERW steel pipe and seamless steel pipe, this huge bridge now is in our life. Ive been here in Zhuhai at August, 2017 and Ive seen this huge and long bridge by myself. Which shocked me at that time. It is here crossing the whole sea and with all of original materials. I think the steel products appear would be the best answer for the complete of this huge bridge. First of all, we know that this long bridge has to hold on the weight of the long distance transportation, and all those steel products strength gives possibility for the strength of the bridge needs. Second, we know that there are lots of wind on the sea. And resistance of corrosion would be one of the most important role for the building of the whole bridge. And of course, galvanized steel products can provide this guarantee. Thanks to the wise engineers and also the high quality steel products so that we can get the distance short between Hong Kong, Zhuhai and Macao.
SSAW steel pipe, known as the submerged-arc welded helical pipe, is widely used in our daily life as well as engineering project.

See website of threewaysteel for overview information. Please visit our product pages for availability and other information specific to each product.
Installation would be an important part among the steel pipes production and selling. As ERW steel pipe supplier or lsaw steel pipes manufacturer, it is necessary to make sure the easy installation between the joint of every steel pipe. Troubles we need to pay attention: A: The pipe ring trouble: we should guarantee it must be stiff enough during the bury to hold pipe rings shape to near circular. B: Thick walls to provide equivalent stiffness is also quite important for various steel pipes. Due to the pressure steel pipes holding during the transportation, so in order to make sure the holding pressure, thick walls are necessary not only internal fluid pressure but also external pressure coming from cars and other products. How to increase the ring stiffness for installation There are lots of options available. We can do this job from longitudinal strength and smooth outer surface. Thus we can solve these troubles and let steel pipes have relative character to hold on the products they transport.

Large-diameter welded pipe is the pipe welds, raw materials are mainly steel sheet and strip, large diameter straight seam welded steel pipe is used, the higher productivity of the kinds of steel, more used in more low-cost steel products one. Large diameter spiral welded steel pipe is used, compared to the straight pipe joints, mechanical strength of the products is relatively high, to save raw materials, but the production is slow. The product is widely used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, is one of the products of China's 20 key development. For the transport of liquids: water supply, drainage. For gas transportation: gas, steam, LPG. For structural purposes: as piling pipe for bridges; piers, roads, pipes and other building structures. In the large-diameter steel pipe welding process, the most commonly used is welded steel pipe, which is mainly used for oil drilling and machinery manufacturing stove pipe can be used as water-gas pipe, large diameter welded pipe for high pressure gas transmission, etc.; spiral welded pipe for oil and gas, piles, piers, etc. seamless steel pipe and welded steel pipe is lower than cost, high production efficiency. Longitudinal simple production technology, high production efficiency, low cost, rapid development. spiral strength than the straight seam welded pipe is generally pipe, can narrow the billet production of large diameter pipe, you can use the same width of the billet production of different pipe diameters, but with a straight seam pipe compared to the same length, the weld length of 30 to 100%. and lower production rate, so the smaller diameter pipe is mostly a straight seam welded, large diameter spiral welded pipe is mostly used. According to different methods can be divided into arc welding pipe, high or low frequency electric resistance welded pipe, gas pipe, stove pipe, Bundy tubes. According weld shape can be divided longitudinally and spirally welded pipe welded steel refers to steel or steel bending round, square, etc. and then welded into shape, the surface of the steel pipe seams welded steel pipe production process simple, high production efficiency, variety specifications, less capital equipment, but generally lower than the intensity of seamless steel tubes. since the 1930s, along with the rapid development of high-quality steel rolling production, and improve the welding and inspection technology, continuous improvement of weld quality, welded steel pipe increasing number of varieties and specifications, and in more and more areas instead of seamless pipe.
