Spiral steel pipe, straight seam steel pipe, steel springboard be better progressly
The situation of the steel market this year is different from previous, traditional demand off-season arrival did not cause too big effect, because of the influence of the low costs and inventory, steel price short-term downside is limited, can predict early November steel prices fly again for a while! As a result, the spiral steel pipe, straight seam steel pipe, steel springboard products prices are going.
Steel market supply and demand in November there was still hope keep good posture, basically have the following reasons:
1, the capacity factor
Recent provinces to work in production on the agenda, on October 29, held in tangshan dissolve excess steel production capacity in October on demolishing, finished the province up to dissolve the steel production tasks this year. Operation, were dismantled the plump, qianan 8 companies nine four of converter or blast furnace burden, dissolve the ironmaking production capacity 4.83 million tons of steel production capacity of 2.9 million tons. Released parts factory shut down after the blast furnace, and the overall out of billet quantity reduced, already in short supply of billet is more short, cause certain influence to the stock.
2, inventory factors
In early October steel inventory and social inventory has fallen sharply, stock fell 113.3 and 902000 tons respectively, to the end of the month continues to decline, infinite close to historic lows. Look from the supply, according to the latest statistics, 164 tangshan steel blast furnace capacity utilization is 76.83%, weeks than fell by 4.88%, with the capacity to further fall to the ground, the development of the environmental supervision, the steel mills cut production maintenance, strained November will exacerbate, balance between supply and demand will be phased order.
3, cost factors,
Considering the steel mills coal, coke available inventory days continues to decline, some even only enough to use two or three days, the supply is still tight, there is a slight upward space; in November Catch up market also appears under its impetus, iron ore imports ore in October index gained about $10 / ton, this will encourage steel costs continue to rise. According to ChengShi of iron and steel group, data statistics, as of November 1, the average profit level of the thread is about 70 yuan/ton, profile is still losing money, the average losses of 30 yuan/tons, in social inventory and steel inventories are not high, steel sales, pressure is not big, the high cost can support steel prices continue to strong.
4, macro stabilizing factor
Obvious signs of macroeconomic stabilisation, demand for steel has had a huge impact. September PPI rebounded 0.5%, rose 0.1%, ended 54 months continue to fall. Due to higher commodity prices, laid the foundation for the expansion of enterprise management and earnings upgrades. Three is the enterprise profit improvement. Industrial enterprises above designated size 9 month before total profit year-on-year growth of 8.4%, 2.2% faster than the first half, 7-15.2% growth in August, September state profit up 27% from a year earlier. Corporate earnings improve, provides the power source for promoting investment. Both investment stabilized, and improve corporate profits, were supportive of steel consumption.
To sum up, the steel market in November, the cost and the influence of low inventory, downward space is limited, but, after all, the off-season fell to demand will continue to fall, the extent of upward will also be limited. Taken together, the probability of strong operation is higher, spiral steel pipe, straight seam steel pipe, steel springboard product prices will still be better progressly.

Galvanized Steel Pipe Using Advantages

Galvanized Steel Pipe Using Advantages

When we talk about the galvanized steel pipes, we usually refer to the hot dipped galvanized steels pipes which are more durable and strengthened than any other types. The cleaning process which the hot dipped galvanized steel pipe uses is far more special in the combination use of the solutions, including the ammonium chloride, zinc chloride or the mixed solutions of both. And it will be sent into the hot dipped groove afterwards. The galvanized steel tube will be with more even layer of the galvanization and the capacity of cohesion, anti-corrosion and anti-dust. All of these as mentioned above will contribute to this kind of steel pipe to be have longer longevity than any other steel pipe kinds.

The regular specification of the galvanized steel tubing which are available from SHINESTAR include 48.3×2.5、48.3×2.75、48.3×3.0、48.3×3.25、48.3×3.5 and other customized types per required.
To maintain these galvanized steel tubes, we should keep in mind about these following steps:
1. Regular clean away the piling-up materials around the steel and control its loading under its limitation.
2. Regular observe if there is any deviation among the steel tube's whole structure of parts of it. If yes, make alteration in time.

Advantages of welded pipe

Advantages of welded pipe

Structural welded pipe (tubing) can be used for a wide variety of mechanical applications. It may be used either statically or dynamically. Its close tolerances, good finish, and dense structure make it ideal for parts such as structural support and parts, frames, racks, trailer beds and trailer components, structural components and supports for buildings, bridges, and highways, conveyors, machine parts, ornamental usages and a wide range of applications in industrial, construction, automotive, appliance and agricultural industries.

Welded pipes are generally more cost effective than the equivalent seamless alternative. They are significantly more available both from distributor and mill stocks and from a mill production lead time perspective. With longer lead times seamless tubes can be exposed to unknown alloying price extras that can fluctuate substantially, hence it can be difficult to plan and predict the true costs for the material. Therefore in addition to faster delivery times for Erw tubes, there is the added advantage of lower economical risk. Erw welded steel tubes generally have better surface quality as compared with manufacturing seamless tubes. Seamless tubes are generally made in multiple steps starting with hot extrusion to form the tube hollows from billets.

Austenitic Stainless Steel

Austenitic Stainless Steel
Low carbon, iron-chromium-nickel stainless alloys containing more than 16% chromium, and 4 to 22% nickel to provide an austenitic structure at normal temperatures. These alloys cannot be hardened by heat treatment, but can be hardened by cold working. They are normally non-magnetic in the annealed condition, but can become slightly magnetic after cold working depending upon composition.

Austenitic Stainless Steel Pipe
Austenitic stianless steel pipe recers to the normal temperature of austenitc stianless steel containing about 18% of Cr, 8%~10% of Ni, 0.1% of C and a stable austenite. Austenitic chrome nickel stianless steel pipe including the famous 18Cr-8Ni steel. On this basis to increase the Cr, Ni content and adding Mo, Cu, Si, Nb, Ti and other elements developed high Cr-Ni series of steel pipe. Austenitic stainless steel pipe is non-meganetic and has high toughness and plasticity. However, the strength of austenitic stainless steel pipe is low which can not be strengthened by phase transformation and can only be strengthened by cold working, such as addign S, Ca, Se, Te and other elements which has a good easing cutting characteristic.

The Safe Ways to Use Scaffolding System and Tubes

In high-rise building construction, every step outside the frame to be paved with bamboo basketry or steel fabric, in addition to deaden 1 m high railing and standing bamboo basketry board. On the outer edge of the scaffold, set up safety set net.

Second, the floor protection measures. Now most of the high-rise buildings are concrete frame constructions, widespread adoption MS pipe scaffolding support steel formwork construction. In order to do the protection of the floor construction, can use floor frame. Guard is equal to the height of the two floors of the building, protecting frame width is equivalent to the length of the building a studio.(floor care on the scaffolding tube can prevent falling to the lateral personnel construction, can also be used as a construction safety channel.)  

Three, floor slanted protective measures Some concrete frame building, caused by a lack of hoisting equipment, inconvenient installation floor frame, using steel formwork support. Preferably in the surrounding buildings, the erection slanted plane, vertical height and construction of building height, the same set-up of ledger, carry on oblique one safety net. (the floor is slanted frame, also can prevent the staff falling to the outside, but in the build-up to pick frame, workers have to switch seat belt) four, socket frame protection measures.

Some high-rise building, using the plug in or the ingate cast-in-place reinforced concrete shear wall construction method, in order to ensure the safety of construction personnel. Tool type socket frame can be used, the height of the socket frame over a layer of floor, can prevent the construction layer surrounding the staff fall outward.

Vietnam steel industry has high growth potential

According to the Viet Nam Steel Association, the country's steel industry has great development potential. Speaking at a seminar titled "Viet Nam's steel industry – rise and fall and development potential" in HCM City on Monday, Dr Nguyen Van Sua the association's vice chairman said that per capita consumption in Viet Nam is 200kg, below the world average of 216kg. he said that "In an industrialised economy, the per capita consumption ranges from 500kg to 600kg."
