Seamless steel anti-corrosion technology requirements

First, anti-corrosion of   seamless steel pipe Seamless steel pipe corrosion according to the requirements of the drawings, the use of epoxy coal tar lacquer outsourcing glass fiber cloth, painted topcoat anti-corrosion. The construction process of the outer wall: pipeline rust removal → coating primer → first time paint → second time paint → glass fiber cloth → topcoat; The inner wall construction process flow: pipeline rust removal → priming → first pass paint → second pass paint → third pass paint Corrosion requirements: 1, Pipeline rust removal the surface of the pipe should be cleaned of grease, ash, rust, and oxide scale before being primed. The use of sand blasting rust quality standards Sa2.5. 2. The surface of the pipe shall be rusted and then primed. The time interval shall not exceed 8 hours. When the primer is applied, the base surface shall be dry. The primer brushing is uniform and full, and there should be no clotting or foaming phenomenon. No brushing...

Seamless steel pipe production equipment requirements

There are some common production equipment for steel pipes. And of course, different types of steel pips would need the different production equipment for the special process too. Today, Tianjin Xinyue Steel Group would have an introduction for production equipment for   seamless steel pipe . Piercing mill: Taking conical-roller as quick-rolling and uniform tubularible thickness, it is widely used in seamless steel pipe's production. It is easy to adjust for feeding angle and the angle. Slight-stretch reducing mill: This kind of machine has three rollers for respective-power-transmission. Its flexible adjustment would make it high-precise outer diameter and superior when used for surface finishing. Rotating heat furnace: It is available for a single or dual-feeding type. Its automated furnace-temperature would save labor's energy. Check www.tjxysteel.com for more details. Contact Email: marketing@xysteelpipe.com Skype/WhatsApp/MP: +8618974849825

Cooling method for seamless steel pipe

Cooling method plays an important role during the production process of   seamless steel pipe . As some defects may happen during the cooling process if we don’t take the rightful plans for it. So we should have a clear understanding for the cooling methods before the production of steel pipe. There are three main categories for cooling method: 1. Fast cooling: this is the cooling method with the process of blowing, spraying and water. We can use fast cooling if we are in need of fast done for the product. Depend on the cold water, we can lower the temperature quickly than air cooling method. 2. Air cooling: according to the literal meaning, we can know the method easily. It is a kind of natural cooling method as we just need to put the steel pipe into the air. To some extent, it is a widely used way to cool steel pipe after hot rolling. 3. Slow cooling: this kind of cooling method is characterized by hot-rolled steel sheets or stacked together so that it cools slowly to...
