Spiral steel pipes are mainly used as fluid pipes and piling pipes. After the steel pipes are made, if they are used for running water, they will generally be treated with anti-corrosion on the inner or outer surface. The general anti-corrosion includes 3pe anti-corrosion, epoxy coal tar anti-corros

Galvanized steel pipe is also called galvanized steel pipe. Galvanized steel pipe can increase the service life of steel pipe and prevent rust to a certain extent. This encyclopedia will introduce the classification, main uses, and process characteristics of galvanized pipes.Classification1. Hot-dip

Welded steel pipe slag is the slag that remains inside the weld. Theoretically, there are three main reasons for slag inclusion in submerged arc automatic welding seam: 1) There are many inclusions in the raw materials (including base metal, welding wire, and flux); 2) The interlayer cleaning is not

Different types of oil casing used in oil production: Surface oil casing protects the well from contamination by shallow water and shallow gas layers support wellhead equipment and maintain the weight of other layers of casing. Technical oil casing separates pressure at different levels so that dril

There will be rust spots on the elbow of the stainless steel pipe, indicating that the elbow is not made of pure stainless steel, but is a stainless steel elbow of electroplating type. The rust spots can be polished with ultra-fine sandpaper and then sprayed with colorless varnish for anti-rust trea

Product name: LSAW steel pipeMaterial: Carbon steelSize: 168.3*7.11*5800mmStandard: API 5LQuantity: 3820 tonsMany cooperations have given the customer full confidence in THREEWAY STEEL.

The spiral seam submerged arc welded steel pipe rotates and starts to enter the soft formation. Under the action of the tri-cone, the drill bit first produces elastic shear deformation of the formation, and then it is removed under the pressure of the tri-cone. In the simulated environment, the soft

Welding, also known as fusion, is a manufacturing process and technique that can join metals or other thermoplastic composite materials (such as plastics) by applying heat, high temperature, or high pressure. There are three welding methods:1. Fusion welding. The workpiece is heated to form a molten

At present, the most common pipe cutting method for spiral steel pipe manufacturers is plasma cutting, which will generate a large amount of metal vapor, ozone, and nitrogen oxide smoke during cutting, which will seriously pollute the surrounding environment. The key to solving the root problem is h

1. Different power sources: the same energy is required, but the power sources of crude oil pipelines and natural gas pipelines are different. The power source of the crude oil pipeline is a centrifugal pump, and the power source of the natural gas pipeline is the compressor.2. Different temperature
