National seamless pipe price one week review

National seamless pipe price one week review 02.19-02.26

  This week the national seamless market prices were slightly up, poor trading performance. 26th  Feb (Fridays), according to International steel development  data: 21 major cities 219 * 6mm specification seamless average price 441 USD/ ton, from Friday (February 19) The average price of 441 USD / ton, up 1 USD / ton.
  East China market this week in most parts of seamless slight increase in prices, price stability maintenance in some areas, up 2 USD / ton. East Φ108 * 4.5 now offer in 460USD / ton, Φ219 * 6 offer in 467 USD / ton. Market turnover performance in general, details are as follows:
  Raw materials: Hot-rolled billet market prices this week, Shandong Granada rose about 8.5 USD / ton, transactions in general. As of press time Friday, Luli reported 305 USD / ton, Pot well 310 USD /ton  , Jiang Xin 308 USD / ton, the price including tax. Jiangsu week of hot-rolled billet prices edged up 10 USD / ton. As of press time, 20 # Huaigang reported 357 USD / ton.
  Feedback from the market to understand the current market, the overall turnover is still not fully open, most traders for seamless pipe prices continued to show a trend of the future and see attitude. Since this week, prices of raw materials continue to pull up and prices rose Linyi area, most businesses began to offer up, but did not improve market transactions, in addition, in the actual operation businesses also retain some concessions space. In terms of stock, due to the current poor market transactions, they are more cautious in stocking process, only some of the common specifications supplement, has no intention to increase the total inventory.
  This week Northwest seamless market price temporarily stable, less turnover. Steel mills, pipe factory in Shandong Province this week, part of the price increase, mainly because of rising billet prices rise, now cold drawn tubes mainstream offer 400 USD / ton, hot-rolled tubes mainstream offer 370 USD / ton, bulk prices are negotiable, which factory stock a large portion of the tube. Merchant said the return of the holiday, the weather gets warmer, demand is expected to heat up, the market mentality better, and other varieties of steel also appears certain to rise, but due to the current terms of seamless pipe upstream of the larger stock traders, coupled with the current actual turnover does not show substantial improvement, the market is still wait and see attitude obviously, continue to wait in the short term.
   Southwest Region Cities seamless pipe prices were mixed this week, market transactions in general.
   South China this week the overall seamless pipe prices stable, the market turnover downturn. Raw materials, this week, Shandong price of hot-rolled billet portion Straight up 5 USD / ton. The price of a whole stable southern China this week, poor turnover. After the Lantern Festival, the market fully opened, the recent North pipe factory price of raw materials and pull up, although demand is not released years ago in southern China due to the high prices, plus years later, despite the wishes of traders to raise prices, but the lack of terminal support efforts. Most traders in maintaining low inventory, a small increase in the overall stock market this week, there is a small market to cover short positions. Expected short-term price weakness in southern China operation.
  The spot market this week, central China seamless pipe market turnover is still subdued, rising prices individual. According to market conditions that inquiry, on the market this week, the small size seamless pipe prices pull up 10 USD / ton, the terminal procurement is still less than normal, the overall stock market volume balance, without substantial replenishment phenomenon. Optimistic about the market outlook, demand is expected to return to normal in March, it is expected that short-term price weakness Central seamless market stability maintenance run.

Spiral steel pipe surface treatment


1, cleaning
   Application of solvent, emulsion cleaning steel surface to remove the oil, grease, dust, smooth agent and similar organic matter, but it can't remove the steel surface rust, oxide skin, flux etc., so it is  only as auxiliary trick.
  2, cleaning tools
   Mainly used the steel wire brush tool on the steel surface polished, can remove loose or tilt the oxide scale, rust, welding slag and other. Manual derusting tools can reach to the grade SA2 level and power tool cleaning can reach to the grade SA3, if steel appearance attached to the solid iron oxide scale, de-rusting tools result is not ideal, amounting to less than anticorrosion construction requirements of the anchor pattern depth.
  3, pickling
   Ordinary pickling treatment with chemical and electrolytic two ways, anti-corrosion pipeline using only chemical pickling, can remove the oxide scale, rust, coating, sometimes used as sand blasting to dispose of. Chemical cleaning is necessary to make the appearance of cleanliness and roughness, but its anchor light, and easy to form the pollution to the environment.
  4, spray (throw) shot de-rusting
   Spray (CAST) shoot de-rusting is after high power motor drive injection (left) blade speed to reverse shot, steel grit, steel shot, wire, minerals and other abrasive under the effect of centrifugal force on the pipe surface spray (throwing incident disposal, not only can eliminate rust, oxide and dirt and steel pipe under the effect of abrasive fierce impact and friction force, but also to achieve the demand of average coarse.
   Spray (CAST) shoot de-rusting, not only can be extended tube surface physical adsorption effect and strengthening anticorrosion layer and the pipe surface mechanical adhesion effect. Thus, spray (parabolic) injection is an ideal method for removing rust corrosion protection of pipeline. Generally speaking, blasting de-rusting primary for inside and outside of the pipe surface treatment, shot blasting (sand) de-rusting basically is used at pipe surface disposal.

1.    Definition of Spiral steel pipe
Spiral steel pipe is also called spiral steel welded pipe or spiral welded steel pipe. Spiral steel pipe use low carbon structural steel or low alloy structural steel trips with a helix angle(called forming angle) rolling into a tube, then the tube seam welded together. The characteristics of spiral welded steel pipes is that it can use a narrow strip steel to produce large diameter steel pipes.
2.    Application of spiral steel pipe Application
Spiral steel pipes is mainly used in the filed of oil and gas pipeline or other large diameter structure pipes.
3.    Produce process
1) Raw material is strip coil, welding wire, flux. All these before producing need strict physical and chemical tests.
2) Strip head and tail docking, using single or double wire submerged arc welding, the steel tube rolled by automatic submerged arc welding machine.
3) Before molding, the strip passes through the leveling, trimming, planing, surface cleaning and conveying, and bending and handling
4) Using the electric contact pressure gauge to control the pressure of the cylinder on both sides of the conveyor, to ensure the smooth delivery of the strip.
5) Roll Forming is by the external control or internal control.
6) Using the welding gap control device to ensure that the weld gap to meet the requirements of welding, pipe diameter, the wrong side of the amount and the weld gap are strictly controlled
7) Welding with the Lincoln Electric welding machine for single or double wire submerged arc welding, so as to obtain the stable welding specification.
8) The welding seam is through the online continuous ultrasonic automatic inspection, to ensure that 100% of the spiral weld nondestructive testing coverage rate. If there are defects, automatic alarm and spraying marks, the production workers adjust the process parameters, timely elimination of defects.
9) Using the the air plasma cutting machine to cut a single pipe.
10) After cutting into a single tube, each batch of steel tube should pass the strict inspection system first, check the weld mechanical properties, chemical composition, blending, surface quality of the pipe and after nondestructive inspection, to ensure that the pipe qualified.
11)  The pipes have continuous acoustic inspection marks, after manual ultrasound and X ray review, if there are defects, after repair, once again after the non destructive testing, until the defects have been eliminated.
12) Each pipe is tested by hydrostatic pressure, and the pressure is sealed by radial seal. The test pressure and time are strictly controlled by the steel pipe water pressure computer testing device. Automatic print record of test parameters
13) ) The pipe end machine the slope angle and blunt edge.

Steel pipe Trend in 2016
  Current market structure of China steel product is full of fierce competition. China Iron and Steel Industry is facing strategic transition from a big steel country to a powerful one after development of more than half century.
  The situation of supply greater than the demand is basically formed, so that the stimulant competition of market is occurred. Price is the focus point of the market competition, and it becomes the important means of all big steel makers and dealers for preempting market shares and creating competition advantages.
  Some managers predict steel pipe prices have bottomed out as they viewed the market fell short of the space will be limited due to the auspicious start after Chinese New Year holiday in accordance with past practice.
  Hebei Shengtian Group Reaguan Pipeline Co.,Ltd the Purchase and sales manager Mr Jiang according to the the raw material price and the past experience forecast that the year 2016 will be better than the year 2015. Seamless steel pipe and pipe fittings will may be increase 5%-10% accordingly. In the monkey year the market will be better and better.
