The difference between precision steel pipe and cold drawn steel pipe 1. The main feature of seamless steel pipe is that it has no welding seam and can withstand greater pressure. The product can be very rough cast or cold dial.
2. Precise steel pipe is a product that has emerged in recent years. It mainly has strict tolerances and roughness on the inner hole and outer wall dimensions.
Characteristics of cold drawn precision steel pipe 1. Smaller outside diameter.
2. High precision can be done in small batch production.
3. High-precision cold drawn products, good surface quality.
4. The transverse area of ​​the steel tube is more complicated.
5. The steel pipe has better performance and the metal is denser.

Differences between hot-rolled precision steel tubes The hot-rolled precision steel tubes are made of continuous-cast round billet slabs or green-rolled slabs, heated in a step-type heating furnace, descaled after high-pressure water, and then passed into the roughing mill. , tail, and then into the finishing mill, the implementation of computer-controlled rolling, after the final rolling after laminar cooling and coiler coiling, a straight hair roll. The heads and tails of straight hair curls tend to be tongue-shaped and fish-tailed. The accuracy of thickness and width is poor, and there are often defects such as wave-shaped, folded edges, and tower-shaped edges. Its heavier roll weight and coil inner diameter is 760mm. After straightening the hair through the cutting line, cutting tail, trimming and multi-pass straightening, leveling and other finishing lines, and then cutting or re-rolling, it becomes: hot-rolled steel plate, flat hot-rolled steel coil, vertical Cut and other products. Hot rolled finishing rolls, after pickling to remove oxide scales and oiling them, are hot rolled pickled coils.
Rotor pump usually beed used to transfer high viscosity liquid. we have rotary lobe pump, roots pump, internal gear pump. stainless steel rotary lobe pump is one kind of food grade pump, pump be used to transfer many kind of food liquid, like: juice, beer, wine, milk, honey, molasses, sugar liquid etc. roots pump is also be called lobed rotor pump, this pump have big capacity and high pressure, it's high suction let pump powerful. pump can be usde to transfer high viscosity lliquid and thick liquid, like: toothpaste, glue, resin, bitumen etc, it's stainless steel material pump also can be used to transfer high viscosity food liquid. NYP series internal gear pump with the heat insulation jacket, it's usually be used to transfer crystallized high viscosity liquid.
