Spiral steel pipe machine for the manufacture of spiral seam welded pipe, It can produce the same diameter of pipe with different width of coil. Or It can produce the different diameter of pipe with different width of coil.
The process: uncoiler - leveler - shear welding station - disc trimmer - Milling Machine - delivery machine - pre-bent guide device - machine - both inside and outside welding equipment - sizing device - line ultrasonic testing equipment - rear axle and pipe cutting devices --- X-ray detection device - flat head chamfering machine - hydraulic press - welding station - weighing measuring - corrosion equipment - spray-standard equipment.
Rolling Machine is the key equipment of spiral pipe production, which is using a three-roll Bending Machine principle of continuous metal strip rolled into a spiral tube, and then single-sided welding, double-sided welding or high frequency welding spiral steel made.

In the second half of the year, the year-on-year figures will continue to improve as the base rate gradually decreases, but downstream demand remains weak. According to the survey, the sales of excavators have cooled in May. Excavator sales are expected to decline in May, and maintain a positive growth year-on-year.
In May, the construction machinery index increased by 1.87 percent in the month. The machinery index, the Shanghai Composite Index, and the Shanghai and Shenzhen 300 Index rose by 10.51%, 4.17%, and 6.22%, respectively. The construction machinery index significantly underperformed the broader market and industry indices, and the infrastructure investment remained relatively stable. Rapid growth, the rise of technology in the second half of the year poses a constraint on the promotion of space.
In April, small excavation and digging are still growing and digging is still falling.
Except for truck cranes, sales of other four major varieties in April were positive compared to the same period last year. From January to April, cumulative sales of excavators, loaders, truck cranes, bulldozers, and rollers decreased by 17.5%, 12.2%, 29.5%, and 16.1% year-on-year, respectively, and the decline was 5.6% more than the first quarter (-25.6%, -19%). , -32.4%, -16% and -6.8%) have been narrowed to varying degrees; in addition to a 21% year-on-year decrease in truck cranes, sales of excavators, loaders, bulldozers and road rollers increased by 5.8% year-on-year in April. 3.9%, 20% and 31%. Excavator tonnage point of view, small digging increased by 20% in April, a positive growth for 2 consecutive months, the middle digging is positive growth of 10%, large digging still fell sharply 54%.
Infrastructure investment constraints in the second half
From January to April, the growth rate of infrastructure investment for investment representatives in the shipping, warehousing, electric heating, gas and water production and supply industries continued to grow at a rapid rate, accumulatively increasing by 24.05%. Among them, shipping and warehousing grew by 23.7% year-on-year, increasing In the sub-sector, the investment in the railway and air transport industries rebounded sharply, the investment in railway transportation increased by 24.6% year-on-year, and the investment in air transport increased by 65%; the production and supply industries of water conservancy environment, electric gas and water increased by 30.8. %, 13.5%, the growth rate has declined, but still in the trend of recovery.
Infrastructure investment maintains a relatively low base for rapid growth. Infrastructure investment last year improved from June, constraining the growth of infrastructure investment growth in the second half of this year.
The second half of real estate uncertainty investment comes from the sustainability of sales
Real estate investment continued to rebound in the first half of the year and uncertainty in the second half came from the sustainability of sales. January-April real estate investment growth rate of 21.1%, compared with 20.2% in January-March continued to rise, continuing the upward trend since the end of last year. The new housing starts area and the growth rate of commercial housing sales also improved. New construction and sales of commercial housing increased by 1.9% and 38.0% year-on-year respectively, which were up 4.6 and 0.9 percentage points from January to March respectively. We are relatively optimistic about real estate investment in the first half of the year and uncertainty in the second half of the year comes from the sustainability of sales.
In the second half of the year, the year-on-year figures will continue to improve as the base rate gradually decreases, but downstream demand remains weak. According to the survey, the sales of excavators have cooled in May. Excavator sales are expected to decline in May, and maintain a positive growth year-on-year. Manufacturers and distributors have doubts about the sustainability of infrastructure construction and real estate investment in the second half of the year and are relatively cautious. Since last year from May onwards, the base figure has dropped significantly, and the cumulative year-on-year data is expected to continue to improve, but it does not mean that the downstream demand has improved.
Maintain the industry "neutral" rating. Maintaining our judgment last month, the impact of IPO restart on market style has already begun to appear. The valuation of large-cap stocks in construction machinery has been supported, and is currently in an empty window of disclosure of earnings reports. The weak recovery of the economy shows that the probability of large-scale investment in infrastructure is not high, there is uncertainty in real estate investment, and the improvement in sales volume of construction machinery is limited, which will restrict the upside of the sector. It is recommended to continue to pay attention to the industry-leading Sany Heavy Industry with a low valuation, and the Hengli Oil Tank with relatively good fundamentals and Anhui Heli.
