- Self introduction

- Required specifications

- Inquire about price/MOQ

Q:How much is the tube?
The first prerequisite we need to determine is: what are the specifications of the steel pipe mentioned? Such as the commonly used steel pipe specifications: diameter 108*4.5, diameter 219*6, diameter 377*10, diameter and wall thickness of steel pipe with different specifications, different weight, so the steel price per meter is different.
Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
Cold galvanizing refers to the zinc plating, the coating is thinner, corrosion resistance is slightly worse, variable color. Environmental pollution.Hot dip galvanized by molten zinc ingots, the coating thickness can be adjusted, good corrosion resistance, and subsequent passivation, can be used for outdoor rust, long service life, some up to 20 years.
Q:What is the difference between steel pipe and round steel?
Widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction. Making ring parts with steel tubes can improve data application rate, simplify manufacturing process, save data and work hours, such as rolling bearings, rings, Jack sleeves, etc., and have been widely used in steel pipe manufacture.
Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
Overview of two processesHot-rolled (extrusion seamless pipe): billet, heating, perforation, three roll cross rolling, rolling or extrusion, tube to tube diameter (or reducing) - cooling - tube, straightening, pressure test (or testing), marking and warehousing.Cold drawing (rolling) seamless steel pipe: round tube to heating to perforation, annealing, pickling, leading to oil (copper), multi pass drawing (Leng Zha), the blank pipe, heat treatment, straightening, pressure test (testing), marking and warehousing.
Q:What does cathodic protection of steel tubes mean?
There are two ways of cathodic protection: sacrificial anode, cathodic protection and impressed current cathodic protection.Sacrificial anode: connect a living metal or alloy to a protective metal to form a galvanic cell. The active metal replaces the protected metal to lose electrons so that the protected metal is not corroded.
Q:What is ND steel pipe?
ND steel also has the ability to resist chloride ion corrosion. ND steel pipe, the main reference indicators (70 degrees Celsius, 50%H2SO4 solution immersion 24 hours), and carbon steel, Japan imported similar steel, stainless steel corrosion resistance compared to higher than these steel grades. Products by domestic refineries and manufacturing units after the use of widely acclaimed, and achieved good results.
Q:What quota should be installed for heating seamless steel pipe?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Q:Seamless steel tube 89X4 meters, how heavy?
According to the theory, each meter is 8.3844 kilograms. If you want to be precise, you'll lose your own weight.
Q:What is the process of spiral steel tube production?
X ray flaw detection: 100% X ray industrial television inspection of internal and external weld seams, and image processing system is adopted to ensure the sensitivity of flaw detection.8. press test: the steel pipe is tested by root test on the water pressure test machine to ensure the test pressure of the steel pipe to meet the standard requirement.9. chamfering flat head: the qualified steel pipe is processed at the end of the pipe to achieve the required size of the end of the pipe10. final inspection: ultrasonic and X ray inspection, and magnetic particle inspection at the end of pipe to check for welding problems and pipe end defects.11., marking: qualified steel pipe for oil, in order to prevent corrosion, and according to user requirements for marking.
Q:DN150 welded steel tubes one meter multiple
DN150 welded steel pipe according to the thickness of two specifications: outer diameter 165mm, wall thickness 4.5mm, 17.81Kg per meter weight, wall thickness of 5.5mm, 21.63Kg. per meter weight
