Prior to ASTM A53M GR.B steel pipe welding quality control 


In the large-straight seam A53M GR.B steel pipe welded steel pipe joint structure, A53M GR.B steel pipe weld and heat affected zone is the easiest place to produce a variety of defects, and weld undercut, pores, slag, lack of fusion, lack of penetration, weld, burn, weld cracking is the main form of welding defects, and are often the cause A53M GR.B steel pipe quality accidents origin.



Prior to A53M GR.B steel pipe welding quality control 
  
1. Make a good quality of raw materials for A53M GR.B steel pipe, after passing inspection before being officially entered the construction site, and resolutely put an end to the use of substandard steel.


2. Followed by the management of welding materials of A53M GR.B steel pipe. Check whether the welding materials for qualified products, storage and baking system if implemented, whether to issue a A53M GR.B steel pipe welding material surface clean and free of rust, electrode coating is intact, with or without mildew.

3. Welding area clean management of A53M GR.B steel pipe. Clean quality inspection weld zone, without water, oil, rust and dirt oxide film, which is to prevent external weld defects produce important role.


4. Select the appropriate A53M GR.B steel pipe welding method should be implemented first test welding, after welding principles.

ASTM A517 steel belongs to the boiler steel plate

-
ASTM A517 steel (also called ASME SA517 standard) is a kind of high-strength quenched and tempered alloy steel plates intended for use in fusion welded boilers and other pressure vessels. The steel shall be killed and shall conform to the fine austenitic grain size requirement. Under this specification, the plate thickness determines the grade selection and the mechanical properties.   A517 grade A steel pates 2.5" in thickness and under, will have minimum Yield Strength of 100 ksi.  A517 grade b steel plates over 2.5" in thickness will have a minimum Yield strength of 90 ksi.  Typical applications include unfired vessels and tanks. ASTM A517 Grade A plates are Pressure Vessel Plate and supplied in the as-rolled condition. The ASTM A517 Gr. A plate may be ordered normalized or stress relieved, or both. ASTM A517 Grade H are Pressure Vessel Plate and supplied in the as-rolled condition. The ASTM A517 Gr. H Plate may be ordered normalized or stress relieved, or both. AS

Boiler operation status of the GB/T 5310 20G boiler steel pipe  Some steel companies produce the fake 20G boiler steel pipe cause the huge problems. Because the creep resistance of 20G boiler steel pipe is lower than other steel pipes and the 20G boiler steel pipe is overheated, the 20G boiler steel pipe wall metal overheated for a long time, which results in accelerated creep at high temperature, decreased strength, and finally the early creep burst occurred. During 20G boiler steel pipe fracture analysis, it was found that the macroscopic surface of the 20G boiler steel pipe fracture was covered with thin blue-purple oxide film, which indicated that the temperature of the 20G boiler steel pipe burst was 800℃, and the section was not smooth due to the effect of high temperature oxidation. There is a thick oxide layer on the inner surface of the  20G boiler steel pipe . The structure of the oxide layer has three layers and usually only when the ambient temperature

Katalor has more useful S235JR steel plate information S235JR steel plate  is a kind steel grade and it is mainly used for steel structural buildings, frames and other steel body under the standard of EN 10025-2.  S235JR steel plate  is for low temperature impacting test under zero centigree. Katalor steel Industrial specialized in S235JR steel plate  in china many decades years. The composition characteristics of S235JR steel plate  are low carbon, less than 0.20%, low alloy and total alloy element less than 3%. Low carbon content in S235JR steel plate  steel is to meet the technical requirements of plasticity, toughness, weldability and cold deformation of S235JR steel plate  used for engineering structural parts. The S235JR steel plate  has Mn as the main additive and conforms to the resource characteristics of our country. Mn not only has a significant strengthening effect on ferrite , but also reduces the cold and brittle temperature of the S235JR steel plate , and
