Lubrication problems in the production of straight seam steel pipes
Straight seam steel pipes need to use a product to match in the production process, that is, a glass lubricant, which was produced with graphite before using the glass lubricant, because at that time there was no such product in the market. Therefore, graphite can only be used as a lubricant, but...Read more -
Adjustment and Control of the Position of High Frequency Induction Loop of Straight Seam Steel Tube
Straight seam steel tube excitation frequency is inversely proportional to the square root of capacitance and inductance in the excitation circuit, or proportional to the square root of voltage and current. As long as the capacitance, inductance or voltage and current in the loop are changed, the...Read more -
Factors affecting the accuracy and resolution of oil casing wall thickness detection
The API standard stipulates that the inner and outer surfaces of the imported and imported petroleum casings must not be folded, separated, cracked or scratched, and these defects should be completely removed. Petroleum casing must be fully covered for automatic wall thickness detection. Currentl...Read more -
Preparation before installation of 3PE anti-corrosive steel pipe
Before embedding 3PE anti-corrosion steel pipe, you need to clean up the surrounding environment first, and conduct technical tests on the commanders and mechanical operators who participate in the clean-up work. At least one line of defense personnel should participate in the clean-up work. It i...Read more -
Why should pipelines be pickled, degreased and passivated?
It is mainly aimed at steel pipes, which are prone to corrosion reactions, and there is a certain hidden danger to equipment damage after corrosion. After removing all kinds of oil, rust, scale, welding spots and other dirt, it can greatly improve the corrosion resistance of steel. If there are d...Read more -
Three processes for forging pipe fittings
Three processes for forging pipe fittings 1.Die forging For small size pipe fittings such as socket welding and threaded tees, tees, elbows, etc., their shapes are relatively complicated, and they should be manufactured by die forging. The blanks used for die forging should be rolled profiles, su...Read more
