How could we forget the sulfate galvanized conversion when we talked about the process characters of galvanized steel pipe. Today, as manufacturer of steel pipes, Threewaysteel pipe company would have a list for sulfate galvanized conversion in hot galvanized steel pipe. Sulfate galvanized conversion: Sulfate galvanized ferroalloy retains only the main salt of zinc sulphate zinc sulfate, and the remaining components, such as aluminum sulfate, alum (potassium aluminum sulfate) can be added in the treatment. This would finally lead to the formation of insoluble hydroxide precipitate precipitation. For organic additives, we can add powdered activated carbon adsorption to remove it. Tests showed that aluminum sulfate and potassium aluminum sulfate is difficult to completely remove in once. And this has a certain degree influence for brightness for brightness of the coating, but it is not serious, as it can be taken out of consumption, which make coating brightness can be restored. The solution passed the treatment, according to the new Process ingredients required additional content, that is the final complete the conversion.Stripped Sunflower Seeds
Steel pipe market has improved in the new year of 2018. We can have an analysis from trading volume increasing and demand. It is obvious that we should have a new market plan for various steel pipes, such as seamless steel pipe, SSAW steel pipe too. First of all, with the new year plas taking out, lots of engineering project would be here and thus the dominant orientation of large diameter straight welded pipe steel would be required. So that SSAW steel pipe would be here for customers. Whatâ??s more, the steel trade business would be carry out in the whole world. Under this situation, there is no doubt that to improve the further development of large diameter thick wall welded steel market and other sizes of steel pipe would be another trend for the steel pipe market. With new yearâ??s coming, new market goal would be carry out step by step and what we need to do is just follow our step of production and doing the best job for our clients.
Physics would tell us that degree of agitation have influence for galvanized steel pipe. Why? Here are some details introduction for it. And it would help us to slow the corrosion for steel pipe once we know the principles for damage of the steel pipe. Once we put the galvanized steel pipe on water, high water velocity can lead the quick erosion corrosion. Thus, here are the troubles caused by scouring of metal surfaces by turbulent water and suspended solids that removes protective scale (12, pp. 2.15, 2.16, 2.25 ; 15, p. 7220). Under this situation, we should know that water movement would have influence for the damage of galvanized steel pipe. As it would lead water aeration to support corrosion. Quickly dissolved oxygen is normal would damage the surface of steel pipe.
As steel pipes supplier, even for ERW steel pipe, we can supply different types with different grade, certification for customers. Today, editor would have a detailed introduction for the physical parameters of ERW steel pipe JIS G3444.

As the saying goes that different strokes for different folks. So does for the choosing of pipes for residence and commercial places. We would like to choose the different pipes according to our taste, pipes function and other factors. For Sara, it would be a consideration for the steel pipe like the galvanized steel pipe. However, which kind of material would you like to choose for your water pipe? Here are some sharing for all of friends. No matter hot or cold water, there is system generally conveying potable hot and cold water. They are applied in drinking water supply, cooking, and cleaning within in residential, commercial, institutional, and industrial buildings. There are several categories for pipes, such as copper pipe, CPVC pipe, galvanized steel pipe, PEX tubing, PVC pipe and stainless steel pipe. Each of them would have special power once you choose it. For example, copper is a long lasting, corrosion resistant, lightweight and strong material used in pipes making. However, we all know that we would decide the pipes option according to price, quality, function and other factors.
A confession coming from SSAW steel pipe touches me deeply.

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.
