Reasons for uneven anti-corrosion thickness of 3PE anti-corrosion steel pipe
The industry standard SY/T0413-2002 does not stipulate the uniformity of the thickness, it stipulates the minimum thickness value of the coating, but it is required that the minimum thickness value of the coating cannot be lower than the thickness value of the low point, not t...Read more -
How to carry out anti-corrosion treatment of spiral steel pipe for water delivery
If the spiral steel pipe for water transportation is used to transport tap water or drinking water, the inner wall is usually made of IPN8710 non-toxic anti-corrosion coating, and the outer wall is made of epoxy coal tar pitch for anti-corrosion. Of course, it can also be used...Read more -
Submerged arc steel pipe welding control measures and forming methods
Submerged arc steel pipe welding control measures: Submerged arc steel pipe has become the steel pipe for large-scale oil and gas transmission projects at home and abroad because of its large wall thickness, good material, and stable processing technology. In large-diameter su...Read more -
Application of straight seam steel pipes in pressure pipelines
1. Definition of straight seam steel pipe pressure pipe: By definition, straight seam steel pipe pressure pipe should include all straight seam steel pipe pipes that use pressure to transport gas or liquid. From the point of view of production, it follows the name of a straigh...Read more -
Causes of Uneven Wall Thickness of Spiral Seam Submerged Arc Welded Steel Pipe
The wall thickness of the spiral seam submerged arc welded steel pipe is uniform, it looks good, the force is uniform, and it is durable. The wall thickness of the spiral seam submerged arc welded steel pipe is uneven, and the steel pipe is unevenly stressed. A phenomenon that...Read more -
What are the casting measures of stainless steel pipe fittings
1. Since the casting shrinkage of stainless steel pipe fittings is much higher than that of cast iron, to prevent shrinkage cavities and shrinkage defects in castings, measures such as risers, cold iron, and subsidies are mostly used in the casting process to achieve sequentia...Read more -
Details of high frequency welding of straight seam steel pipe
High-frequency welding process: Straight seam steel pipe is a steel pipe made by rolling a long strip of a certain specification into a round pipe through a high-frequency welding unit and welding the straight seam. The shape of the steel pipe can be round, square, or irregula...Read more -
The difference between cast steel flange and forged steel flange
The cast steel flange has an accurate blank shape and size, a small processing amount, and low cost, but has casting defects (pores, cracks, inclusions); the internal structure of the casting is poorly streamlined (if it is a cutting part, the streamlined form is even worse); ...Read more -
Connection problems between steel pipe fittings
Steel pipe fittings are parts that connect tubes to pipelines. According to the connection method, it can be divided into four categories: socket fittings, threaded fittings, flanged fittings, and welded fittings. Mostly made of the same material as the pipe. There are elbows ...Read more
