Plastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, and plastic-coated composite steel pipes, are based on steel pipes. A layer of plastic anti-corrosion layer or plastic anti-corrosion layer is fused to the inner surface of the steel pipe (bottom pipe) thr

(1) During the extrusion process, the temperature of the lining of the spiral steel pipe continues to increase as the extrusion process proceeds. At the end of the extrusion, the temperature in the area of the inner wall of the lining close to the extrusion die is relatively high, reaching 631°C. Th

Eccentric steel pipes are most likely to occur during the production process of hot-rolled steel pipes, and most of them occur during hot piercing: Based on the anatomical analysis of steel pipes rolled by automatic pipe rolling machines, we believe that the perforated capillary pipes are rolled by

Cleaning methods for large diameter steel pipes:1. Shot blasting and rust removal: A high-power motor drives the blades to rotate at high speed, so that steel sand, steel shots, wire segments, minerals and other abrasives are sprayed and blasted on the surface of the steel pipe under the action of c

Oil casing is a large-diameter pipe that plays a role in fixing the walls or wellbore of oil and natural gas wells. The casing is inserted into the wellbore and fixed with cement to help the wellbore separate the rock formations and prevent the wellbore from collapsing while ensuring the circulation

1. Use solvents and emulsions to clean the surface of anti-corrosion spiral steel pipes. This can remove organic matter on the surface of spiral steel pipes, but it cannot remove surface rust, oxide scale, flux, etc., so cleaning can only be used as an auxiliary means.2. Use wire brushes, sandpaper,

In oil drilling operations, an oil-slotted pipe is an important piece of equipment, often used for early completion or oil production and control. Currently, the most commonly used oil-slotted pipe is a wire-wound slotted pipe. The manufacturing method of this kind of oil-slotted pipe is to wind a s

Stainless steel pipes are very distinctive in terms of model specifications and appearance performance. First of all, the thicker the pipe wall of this type of stainless steel pipe, the higher its cost performance and practicality will be. The thinner the pipe wall, the greater the processing cost w

Boiler heating surface steel pipes work for a long time under the action of high temperature, stress, and corrosive media. When the steel pipes cannot withstand the load of their working conditions, different forms of damage will occur and cause accidents. Common accidents of steel pipes on the heat

1) Sizes of steel wire, steel bars, in-diameter steel pipes, wire ropes, etc. can be expected in a well-ventilated storage shed, but the bottom layer needs to be thatched.2) Some enterprises and small companies can store steel products, thin steel plates, steel strips, silicon steel sheets, small-di
