PPGI & GI Coil

图片
PPGI & GI Coil Product Description PPGI sheet  is the ultimate product for deep processing of sheet by steel companies in the world today. With light weight, beautiful appearance, good corrosion resistance, etc., it is widely used in construction, light industry, home appliances and other industries. During production, use a crane to roll up the raw materials on the receiving platform of the color coating unit, and then use a transport trolley to transport the steel coil  to the coil seat in front of the color coating unit, remove the steel strip here, and then load the trolley to remove the raw steel The coil is loaded on the uncoiler, and the strip head is automatically guided to the cutting head by the belt guide device. The strip is sewn with the previous loop on the sewing machine. The stitched steel strip first enters the pre-cleaning section for alkaline water washing, alkaline water scrubbing, and hot water washing, and then enters the looper after being dried by hot air. A

Welded Pipe Manufacturing Process

图片
Welded pipe is manufactured from plates or continuous coils or strips. To manufacture a welded pipe, the first plate or coil is rolled into a circular cross section with the help of a plate coiler or in a continuous process by means of rollers. Once the circular section is rolled off the plate, the pipe can be welded with or without filler material. Large sizes of welded pipes can be manufactured without any upper limit. Welded pipes with filler material can be used to manufacture long radius elbows and bends. Compared to seamless pipes, welded pipes are cheaper and weaker due to the weld seam There are different welding methods for welding pipes. ►ERW- resistance welding ►EFW-Electrofusion welding ►HFW-High Frequency Welding ►SAW-Submerged arc welding (long seam and spiral seam)   ERW steel pipe manufacturing process In  the ERW / EFW / HFW pipe  process, the first plate is formed into a cylindrical shape and the longitudinal edges of the formed cylindrical shape are welded by flash w

Seamless pipe manufacturing process

Seamless pipe is the strongest of all pipe types because it has a uniform structure over the entire length of the pipe. ►  Seamless pipe  is manufactured in the same size and schedule. However, the manufacture of large diameter pipe is limited. Seamless pipe is widely used in the manufacture of pipe fittings such as elbows, bends, and tees. ►A detailed explanation of the various manufacturing processes.   Mandrel mill process In mandrel-rolled pipe manufacturing process, billets are heated to high temperatures in a rotary furnace. The cylindrical hollow, also known as the female hollow, is produced with the help of a rotary piercer and a set of roller devices that hold the piercer in the center of the billet. The outer diameter of the perforator is approximately the inner diameter of the finished tube. With the help of this, the alignment of the outer diameter and thickness of the secondary rolls is achieved.     Mannesmann Plug Mill Pipe Manufacturing Process Mannesmann was a German e

Why do I need a roof inspection service?

Stainless Flange

Stainless Flange Product Description Flange is a part that connects two pipe ends. Flange connection is defined as a combined sealing structure in which flanges, gaskets and bolts are connected to form a set of detachable connections. Add gaskets between the two flanges, and then tighten them with bolts. Different pressure flanges  have different thicknesses and use different bolts. When the pump and valve are connected to the pipeline, the parts of the equipment are also made into corresponding flange shapes, also known as flange connections . More information visit Usually closed bolted parts are also called flanges, such as the connection of ventilation pipes, such parts can be called "flange-type parts". If this connection is only a part of the device, such as the connection between a flange and a water pump, it is not suitable to call the water pump a flanged part. But relatively small valves can be called flanged parts. Product Stainless steel flange, stainless steel pi

Therefore, here are some reasons why "steel and aluminum are different". ✱ Ductility Aluminum is a highly malleable and flexible metal, which is why it is about 20% more expensive than steel. Few roofing profiles require thick aluminum, which would make the price higher. Aluminum is only about 2/3 the amount of steel and can be very expensive to use. The syste
