basic knowledge of pipe fittings pipe

Basic knowledge of pipe fittings tube pipe the first part of a steel pipe seamless steel pipe according to manufacturing methods and welded into two. Seamless high-quality carbon steel or alloy steel, with hot and cold rolling (drawing) of the points. Welded steel pipe is rolled into tube-shaped plate

To sew on the seam or spiral welded in the manufacturing methods, are divided into low pressure liquid delivery welded steel pipe, spiral seam welded steel pipe directly welded steel pipes, welded tubes. Seamless steel pipe can be used for a variety of liquids, gas pipelines. Welded pipes for water pipelines, gas pipelines

, Heating pipes.

1, welded steel pipe

1.1 low pressure liquid delivery and galvanized welded steel pipe welded steel pipe

Welded steel pipe for low pressure liquid delivery, is a soft carbon steel, is the most commonly used pipeline project of a small diameter pipes for conveying water, gas, steam and other media, according to the different surface quality, plated into Zinc pipe (commonly known as galvanized iron pipe) and non-galvanized pipe (commonly known as the Dark Iron

Tube). Plating on the inside and outside the wall layer of the protective layer of zinc than non-galvanized around 3% -6% heavy. Divided according to their different pipe wall thickness: thin-walled tube, general management and control of three thickening. Thin-walled tube should not be used for the transmission medium can be used as casing.

1.2 Straight Seam Welded Steel Pipe rolling

Straight seam welded rolled steel tube, welded steel pipe and the scene can be divided into blocks with a steel roll into a straight seam welded steel pipe welded. Several wall thickness can be made.

1.3 spiral seam welded steel pipe

Spiral welded steel pipe is divided into high-frequency automatic submerged arc welded steel pipe and two.

a. Spiral Seam Submerged Arc Welding Pipe by the pressure of high and low transmission medium is divided into two categories A pipe and B pipe. A carbon steel pipe for general use Q235, Q235F and ordinary low-alloy structural steel welding 16Mn, B tube with Q235, Q235F, Q195 and other steel welding, as a low pressure

Fluid power transmission pipe

b. High-frequency welded steel pipe spiral seam high frequency welded spiral seam steel pipe, still no uniform product standards, generally use the ordinary carbon steel Q235, Q235F and other steel manufacturers.
