- 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 is the production process of seamless steel tube?
Main production process of cold rolled (drawn) seamless steel tube:Blank preparation, pickling, lubrication, cold rolling (drawing), heat treatment, straightening, finishing and inspectionThe production process of seamless steel tube in general can be divided into two kinds of hot rolling and cold drawing, cold-rolled seamless steel pipe production process than hot-rolled billet to complex, first to three roller rolling and extrusion to sizing test, if the tube through the cutting machine cutting surface without crack growth response after cutting blank about one meter. Then enter the annealing process, annealing and pickling to use acid pickling liquid, should pay attention to the surface if there are a lot of bubbling, if there are a large number of bubbling pipe shows that the quality is not up to the standard. The appearance of cold rolling seamless steel tube shorter than hot-rolled seamless steel pipe, cold rolled seamless steel pipe wall thickness is generally higher than hot-rolled seamless steel pipe to be small, but the surface looks better than thick wall seamless steel pipe is more bright, rough surface is not too much, not too much burr diameter.
Q:What are the main aspects of precision steel tubes?
Products according to their application areas are divided into: automotive, precision machinery tubes; power plants, nuclear power tubes; titanium and titanium alloy tubes; chemical tubes; varieties include colored, black; seamless; welding; general and special-shaped
Q:What are the specific differences between flexible pipes and rigid pipes?
Choose from the waterproof performance:A rigid waterproof sleeve is a steel pipe with an outer wing (a steel ring made of a steel ring), mounted in the wall (mostly concrete walls), used for general pipe wall crossing, and is beneficial to the waterproof of the wall;The flexible waterproof casing except external wing ring, flange ring and internal wire like, and have complete sets sold, but also their own processing, for pipeline damping needs, such as pipes and pumps connected through walls.
Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
1.: Construction of the underground pipeline, levy more pumping, boiler hot water transportation etc..2., mechanical processing, bearing sets, processing machinery parts.
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's the actual size of the DN25?
Different materials of steel pipe, nominal diameter of the same, then its outer diameter is the same, diameter = outside diameter -2 times, wall thickness.
Q:Is the electric pipe used with steel pipe or PVC pipe?
Electric pipe laying is generally divided into the following circumstances:1) the explosion-proof area must be galvanized steel pipe and explosion proof flexible pipe (used for front end equipment connection);2) non explosion-proof area can use KBG pipe or PVC tube, the former is higher cost, but the installation is firm, the latter is low cost, easy to construction, and in the rain where it will not rust, but compared to the KBG pipe may be damaged.
Q:What is the process of spiral steel tube production?
Shear forming: on the production line will be along the outer edge of the spiral plate winding tube.
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
