Causes and measures of pipe weld porosity
Weld pipe weld porosity affects not only the pipeline denseness, resulting pipeline leakage and corrosion will be induced point seriously reduce the weld strength and toughness. Factors weld porosity are: the flux in the water, dirt, oxide and iron filings, welding ingredients and cover thickness...Read more -
Coated pipe transportation
The point to note of coated pipe during transportation 1) When using special hooks, angle steel and sling of not less than 300, in order to avoid excessive damage to the lateral pull spout. 2) anti-corrosion pipe loading must meet: a loading height of not more than two layers. b corrosion pipe be...Read more -

DSAW(Double-sided spiral submerged arc welded pipe)characteristics
DSAW(Double-sided spiral submerged arc welded pipe)characteristics: production process of welded pipe is simple, high efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than dsaw pipe and can narrow the billet production of large diameter pipe, you...Read more -
Classification and role of tubing
1. Tubing classification Tubing can be divided into the tubing (NU), upset tubing (EU) and the overall joint tubing. Flat means the oil casing pipe end without directly threading thicker and bring couplings. Upset tubing means after two pipe ends through external upset, then threading and bring c...Read more -
Ceramic-lined steel pipe
Ceramic-lined steel pipes are manufactured by a high-tech production process and are made of a breeding high-temperature synthetic clutch. It is made of corundum ceramic and the transition layer consists of three layers of steel from the inside out. Ceramic-lined steel pipes represent ceramic-lin...Read more
