pittsburg ca steel pipe Spiral welded pipe: it is to roll the low carbon carbon structural steel or low alloy structural steel strip into tube billet according to certain spiral Angle (called forming Angle), and then weld the tube seam to make it. It can use narrow strip steel to produce large diameter steel pipe.Its specification is indicated by the outer diameter * wall thickness, and the welded pipe shall ensure that the water pressure test, tensile strength and cold bending performance of the weld meet the requirements.
Pittsburg Ca Steel Pipe
A simple comparison of the technical characteristics between spiral welded pipe and straight welded pipe:
so it becomes impossible to completely absorb the dust.3. Because the cutting part is far from the dust removal suction inlet, the wind force reaching the suction inlet is difficult to pump the dust.
For this reason, the design principle of the vacuum cover is:1, the dust collector suction air volume is greater than the total amount of dust and pipe air generated by plasma cutting, should be in the spiral steel tube internal forming a certain amount of negative pressure chamber, and try not to let a large number of external air into the spiral steel tube,
in order to effectively dust into the dust collector.2, the position after the cutting point of the spiral steel pipe will be blocked by smoke, suction inlet to try to avoid cold air into the spiral steel pipe inside, in the spiral steel pipe internal space to form a negative pressure
Install the smoke baffle plate on the trolley inside the spiral steel tube and place it at the plasma gun cutting point of about 500mm. After the spiral steel tube is cut off, it will stay for a while to fully absorb the smoke.Note that the smoke baffle should be accurately positioned after cutting.In addition, in order to make the traveling trolley supporting the dust baffle coincide with the rotation of the spiral steel pipe, the wheel Angle of the traveling trolley must be consistent with the Angle of the inner roller.
The Process Flow
has more than ten years history company which located in Lecong Iron and Steel World, a well-known steel distribution center in China, with superior geographical position and convenient water and land transportation.
We are a direct-selling manufacturer specializing in the research and development of spiral steel pipes, steel coiled pipes, anti-corrosion steel pipes inside and outside. Since its inception, the company has been guided by a brand-new thinking of steel pipe product market based on the business philosophy of honesty, pragmatism and knowledge-seeking.
