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:How to perform nondestructive inspection of steel tubes
The detection principle is based on the ferromagnetic material is magnetized in a magnetic field, discontinuity materials and products (defects) produce leakage magnetic field, magnetic powder adsorption (or detecting) and appear (or on the instrument display). Therefore, this method can only be used for the inspection of the surface or near surface defects of ferromagnetic materials or products.
Q:What is the buckling type thin-wall steel pipe? What is a tight set of thin-walled steel tubes? What's the difference between the two?
The thread of the tightening (JDG) joint is unified with an outer thread, a wall thickness of 1.5mm, and a button (KBG). The thread of the joint is an internal thread, and the wall thickness is 1.0mm. Withholding type joint for the use of the same company and pipe connection to matching products with complete connection clamp buckle. Fastening and pressing type correctly connected and locked after no need to do a cross ground.
Q:How to make the internal tooth of the steel pipe?
At present, in our country, 300MW or 600MW or more large capacity sub critical and supercritical thermal power boilers are designed or imported abroad. Membrane internal wall tubes are widely used in membrane water wall.
Q:The plastic pipe and steel pipe difference
The steel plastic pipe is a general term, which includes plastic pipe, plastic lined pipe. Plastic pipe external coating, zinc coated and so on in Shanghai, Fujian, Portland, professional in this area
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless steel tube is a kind of steel strip with hollow section and without seams.
Q:What's the difference between straight steel pipe and seamless steel pipe?
Observe whether there is weld seam. Welded pipe without treatment, there are obvious weld, there are bulges, like scars. A better point will shave off the weld, but there is a distinct difference between the eye and the eye. Also a small number of pipe will be processed after cold rolling, surface roughness and accuracy are relatively high, may be counterfeit seamless pipe sales. Careful observation will still show that the pipe wall will have a continuous spiral, metal luster slightly brighter, that is, the original welding seam, metallographic structure and other parts of the difference. To tell the truth, the layman would have to observe that it might be a little difficult.
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 difference between steel pipe and round steel?
The middle of the steel pipe is hollow, and the round steel is solid. When compared with the solid steel such as round steel, the steel tube has the same flexural strength and torsion strengthLight weight, is an economic section of 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.
Q:What is the outer diameter and wall thickness of DN40 steel pipe?
DN40, refers to the diameter of 40mm, that is, an inch and a half, there are welded pipe and galvanized pipe,Ordinary wall thickness 3.5mm wt 3.84kg/mThicken 4.25mm weight 4.58kg/m
