How to distinguish steel pipes in the market professionally

Are you still confused about how to distinguish steel pipes in the market so that you will make a good choice for your desired products finally? DongPengBoDa Steel Pipe Group, a professional steel pipe manufacturer in China would like to give you the possible answers as follows.

1. Material Classification
Generally, steel pipe can be divided into: carbon pipe and alloy pipe, stainless steel tubes. Carbon tube can be divided into ordinary carbon steel and quality carbon structural tube. Alloy tube can be divided into: low-alloy tubes, alloy pipes, high alloy pipes, high-strength pipe. Bearing tube, stainless acid-resistant pipe, precision alloys (such as Kovar alloy) pipe and high temperature alloy pipe.
2. Production Methods
Steel pipe according to production methods can be divided into two major categories: seamless and welded steel pipe. Seamless steel pipe according to production methods can be divided into: hot-rolled seamless tube, cold drawn tubes, precision steel tube, thermal expansion tubes, pipes and cold extrusion spinning tubes. Seamless steel pipe with high-quality carbon steel or alloy steel, hot-rolled, cold-rolled (pull) of the points.      Welded steel pipe is rolled into a tube-shaped plate to the seam or spiral seam welded, in the manufacturing method, divided into low pressure liquid delivery welded steel pipe, spiral seam welded steel pipe, direct volume welded steel pipe, welded pipe. Seamless steel pipe can be used for a variety of liquids, gas pipelines. Welded pipe can be used for water pipes, gas pipes, heating pipes and so on.
3. Feature classification by plating coating
Characteristics of steel coated by coating the surface can be divided into two major categories: clarinet (not plated coating) and coating the coating tube, as such black steel pipe and galvanized steel pipe in the current market. Hot dipped galvanized steel pipe has been considered popular a lot among many users today. For one thing, the galvanization process protects the steel from rusting damage that can occur during transportation, installation and service. The zinc layer on the surface of pipe can form a barrier protection for steel products to extend the service life in applications. For the other thing, this layer is also resistant to wear and scratch, which makes the steel look more attractive. On the other hand, possession of the outer coating pipe coating, inner coating tubes, coated inside and outside the tube. Coatings are commonly used plastic, epoxy, coal tar epoxy, and various types of anti-corrosion coating of glass material.
4. Shape classification by cross-section
In the current steel pipe market, hollow section tubes have extremely diverse variety of specifications, performance requirements. All of these should be as user requirements or changes in working conditions to be distinguished. Typically, the cross-section shape steel products according to production method, pipe materials, connection methods, plated coating characteristics and the specific applications. Variable cross-section (or tapered) pipe is the pipe length direction along the cross-section shape, inside and outside diameter and wall thickness and other periodic or aperiodic changes in the occurrence of the pipe. The main are: outer conical tube, conical tube inside and outside ladder pipe, ladder within tube, cycle cross-section of pipe, corrugated pipe, spiral pipe, steel pipe with a heat sink and the barrel with a double-track and so on.
