The transportation of oil and gas through pipelines requires a certain pressure. The longer the pipeline, the higher the pressure required for oil and gas transportation. The pressure of long-distance pipelines is generally between a few MPa and more than ten MPa. Therefore, the pipeline must have S
1. The use of large-diameter straight seam welded steel pipes can be divided into oil well pipes (casing pipes, oil pipes and drill pipes, etc.), pipeline pipes, boiler pipes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geological pipes, chemical pipes (high-pressure Fertil
The spiral steel pipe is drilled in rotation and begins to enter the soft formation. Under the action of the tritone, the drill bit first produces elastic shear deformation of the formation and then is removed under the pressure of the tritone. In the simulated environment, the soft soil is homogene
Routine maintenance is required when thick-walled steel pipes are used:Thick-walled steel pipes are widely used steel varieties. It directly affects the economic benefit and personnel's life. All countries in the world attach great importance to the inspection of thick-walled steel pipes and adopt v
Horizontal fixed welding of thick-walled stainless steel pipes:Stainless steel pipe is a hollow long strip of steel, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. Stainless steel pipes are lighter in weight when they have the same bendi
Product name: Anti-corrosion steel elbowSize: customized sizeStandard: ASTM A234 WPB WPC Project Location: BrazilThe order is from an old client, who needs to applicate for the energy transportation project. When the product arrived at the energy transportation project location, it was quickly used.
The main technical characteristics of spiral steel pipe:During the forming process of the spiral steel pipe, the steel plate is uniformly deformed, the residual stress is small, and there is no scratch on the surface. The processed spiral steel pipe has greater flexibility in the range of diameter a
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 submerged arc steel pipe w
What they have in common is that they all belong to inner and outer plastic-coated steel pipes, but fire-fighting plastic-coated steel pipes are only one category of inner and outer plastic-coated steel pipes.We are already familiar with the plastic-coated composite steel pipe inside and outside. Wi
Introduction of anti-corrosion on the inner wall of large-diameter steel pipes:1. Before processing all steel pipes, the steel plate on the inner wall side of the large-diameter steel pipe shall be derusted until the metal is exposed to metallic luster (whitening). It should meet the sa2.5 standard
