Gb elbow and two standard elbow difference

Gb elbow and two standard elbow difference  

Gb elbow manufacturers introduce gb elbow and the two standard is different: GB elbow products and the appearance of the two standard elbow products is the same, but the thickness and size of the gb elbow products, the size and wall thickness of the two standard elbow products is not as uniform as gb elbow fittings.  Gb elbow is divided into two kinds of seamless GB elbow and straight seam GB elbow, but two kinds of GB elbow products in the pipeline installation Angle is the same, GB seamless elbow fittings compared to straight seam GB seamless elbow pipe price is slightly higher, is the use of GB seamless steel pipe push machine and mold push shape.  Straight seam gb elbow is made by welding, and the weld is ground away.  The customer called the fake seamless gb elbow when ordering.  Then there is the elbow processed with the plate.  That is the top weld, the bottom weld, the straight pipe has a vertical weld (usually used for large diameter pipes), seamless nothing.  You can see it with the naked eye.  The longitudinal welds should be staggered when the straight seam pipe sets are paired.  Stamped elbows do not cause erosion, pitting, rust or wear.  Stainless steel is still one of the high strength metal materials used in construction.  Because of its good corrosion resistance, stainless steel enables structural components to maintain engineering design integrity.

 Stainless steel stamping elbow has a long service life in the service process, which can meet the needs of pipeline installation in construction and petrochemical industries.

All metals react with oxygen in the atmosphere to form an oxide film on the surface.  The iron oxide formed on ordinary carbon steel inherits oxidation, so that the corrosion is expanding, forming holes.  The surface of carbon steel may be secured by electroplating using paints or oxidation-resistant metals such as zinc, nickel and chromium, but, as is known, this protection will not be a film.  In addition, after pushing the head is generally the front end of the outer diameter is large, to be corrected through the correction mold.  The whole die is actually a press, to have a set of dies, two semi-arcs, one at the top and one at the bottom.  The corrected outer diameter meets the size requirements of the finished product.  The wall thickness is controlled by the wall thickness of incoming material.  The tolerance of wall thickness for both elbow and pipe is the same, ±12.5% for both.  In addition to chromium, commonly used alloy elements and nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of various uses of stainless steel stamping elbow and function.

 According to the above introduction of elbow pipe fitting products, each customer has some understanding of the difference between national standard elbow and second standard elbow. If you do not understand our company welcomes your consultation!
