Product Description:

1Structure of DIN 1626 Precision Small Tube: 

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe. 

 

2‍‍Main Features of DIN 1626 Precision Small Tube:

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

- 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:How to distinguish seamless pipe and welded pipe?
The way to distinguish seamless pipes and welded pipes is to see if there is weld marks on the port.
Q:Heating system DN40 and DN32 welded steel pipe how to connect?
Is the wire: also called pipe thread connection, the malleable steel pipe fittings, malleable iron is the thread connection using DN40X32 diameter hoop.
Q:What does cathodic protection of steel tubes mean?
Applied current: a macro cell consisting of a protected metal piece and an insoluble auxiliary component. The negative electrode of the battery is connected to the metal to be protected. The power supplies the electrons so that the metal is not corroded by missing points.
Q:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
Hot rolled seamless tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..
Q:What's the material of Q325 steel pipe?
Plain carbon structural steelIt's a kind of steel material. Q stands for the yield of this material, and the latter 325 means the yield value of this material, at around 325. And the yield value will decrease as the thickness of the material increases.
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:How long is the seamless tube?
Generally finished seamless steel tubes are less than twelve meters, mainly for the convenience of shipment.In times of rolling (processing), the steel pipe can reach 80 meters or longer.
Q:What does "1.5" steel tube mean?
This is neither an outer diameter nor an inner diameter; it should be related to an English unit at the beginning of the pipeline development; it is usually used to describe galvanized steel pipes; it corresponds to the English units as follows:4, in charge of: 4/8 inches: DN15;• 6 in charge: 6/8 inches: DN20;• 1 inch tube: 1 inches: DN25;• inch two tubes: 1 and 1/4 inches: DN32;• inch half tube: 1 and 1/2 inches: DN40;- inch tube: 2 inches: DN50;• three inch tube: 3 inches: DN80• four inch tube: 4 inches: DN100;
Q:DN150 welded steel tubes one meter multiple
The theoretical weight table of welded steel pipe (Kg) can be checked, and the outer diameter and wall thickness can be measured according to the formula.For example: DN150 welded steel pipe, diameter 165mm, thickness 4.5mm, weight kg per meter.Welded steel pipe theoretical weight (Kg/m) = (165-4.5) * 4.5 * 0.02466=17.81Kg
