- 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 can seamless steel tubes be produced?
The material of rolling seamless tube is round tube blank, and the billet is processed by cutting machine to grow about 1 meters, and sent to the furnace by conveyor belt. The billets are heated into a furnace and the temperature is about 1200 degrees celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key problem. When the round billet is released, it should be punched through the pressure piercer. The most common punching machine is a cone roll piercer, which has high production efficiency, good product quality, large perforation and expanding diameter, and can be used in various steel grades. After the perforation, the round tube blank has been successively rolled, rolled or squeezed by three rollers.
Q:Heating system DN40 and DN32 welded steel pipe how to connect?
Welding: AC arc welding machine welding. Mode 1: apply to the medium of non demanding piping, DN40 steel pipe necking and DN32 steel pipe butt welding, or directly DN32 steel pipe into the DN40 internal welding. 2: the pipeline requirements apply to the inner wall of smooth transition, reducing short circuit welding for DN40x32 suppression of this mechanism are used for connection pipe seamless steel pipe high pressure pipeline connection, no special requirements, not commonly used welded steel pipe. Connection of mechanism fittings is not only costly, but not necessary unless special requirements are required!
Q:What are the lengths of scaffold steel tubes?
Scaffolding steel pipe standard length is 6 meters, for easy use, respectively, 6 meters, 3 meters, 2 meters, 1.5 meters, 1 meters, etc., if there is a special length, you need to intercept.
Q:Difference between cold rolled steel pipe and common steel pipe
3, the caliber of cold-rolled steel tube is smaller than that of hot rolled steel tube4, from the price point of view, cold-rolled steel pipe is 1000-2000 tons more expensive than hot-rolled steel pipe
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
Classification is not the only way, fastener type steel pipe scaffolding is divided by force, and the latter 2 are classified according to the structure.
Q:What is lined pipe?
Pipe lining is a new technology in recent ten years of development, also called composite pipe conveying fluid with different needs, the use of different materials to make the durability of the pipeline inner wall and outer wall of pipeline, to ensure the purity of the fluid, pipeline adaptability, performance is greatly improved, more extensive use.
Q:What's the difference between No. 20 steel pipe and 27SiMn Steel Pipe?
Cold plastic deformation and for bending, rolling, bending and hammer arch processing, arc welding and contact welding welding performance is good, when the thickness is small, prone to strict requirement of shape crack or complex shape parts. The cold or normalizing condition of cutting is better than that of annealing. It is generally used to make the material with little force and high toughness.
Q:What does "HBB" glass steel pipe mean?
HBB glass fiber reinforced plastic cable protection tube is suitable for power, communication and communication cables laying protection pipes in all kinds of occasions. Especially in the traffic crossing through cable and cable bridge across the river, the use of the special environment, more fully reflects its simple construction, high strength performance, widely used in the construction of infrastructure, transportation, electricity, communications and other fields of Civil Aviation Airport
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless pipe featuresFirst, the product of the wall is thicker, it is more economical and practical, the wall thickness of the thinner, processing costs will be substantially increased it; secondly, the product process to determine its performance limitations, generally low precision seamless steel pipe: uneven thickness, tube inner surface brightness low and high cost of fixed length, and the inner surface pitting and black spots difficult to remove; the detection and plastic third, must be processed offline. Therefore, it has its advantages in high pressure, high strength, mechanical structure and timber.
Covering an area of 150,000 m2, is with total assets of 500 million RMB,with annual production capacity of 500,000 tons. Currently, we has approximately 1000 employees, including many top-rankingtechnical experts and excellent management team.
