How to Choose ASTM A500 #ERWSteelPipe Manufacturers - Production Conditions: Technical Capabilities: Evaluate the manufacturer's production facilities, technical equipment, and technical R&D personnel. High-quality products require integrated production facilities, first-class production equipment, and professional production technicians. Comparative Analysis: Compare the production conditions of different manufacturers to assess the reliability and quality assurance of their products.   - Meeting Actual Needs: Specifications and Models: Ensure that the manufacturer can provide steel pipe specifications and models that meet your actual needs. Consider the material, processing technology, and other relevant conditions to select the appropriate steel pipe products.   - Price: Cost Considerations: Take into account the price of ERW tubing, considering factors such as material selection, production process, pipe diameter, and pipe length. Price Comparison: Compare price schedules from different manufacturers, keeping in mind market price fluctuations. Ensure the selected option fits within your budget while meeting your specifications and quality requirements. For any further request, please contact: sales@union-steels.com

BS EN 12952-5 2021. Post bending heat treatment. 7.3.9.2. Austenitic Tubing. Post bending heatreatment will normally not be required for cold bent Austenitic tubing. why not pbht, what is the logic.because Austenitic Stainless Steel can be hardened by cold work ,due to this corrosion resistance will come down?? why the different version on PBHT of cold worked ASS.. As per ASME ,if strain exceed 15%, PBHT is required

"3.1.2.6 The pump suction line shall have a straight run (typically five diameters) between the suction flange and first elbow, tee, valve, reducer, permanent strainer, or other obstruction sufficient to ensure stable uniform API RP 686 is a recommended practice flow at the pump suction nozzle. Note: A piping straight run length of five pipe diameters, based on the pump suction nozzle size, is usually sufficient to ensure stable and uniform the pump suction nozzle. In some situations, the type and orientation valves and elbows in the pump suction line may affect the flow distribution to the impeller and necessitate a longer piping straight run length. Flow straighteners may also be utilized to reduce the piping straight run length." The straight run length of five pipe diameters is usually sufficient to ensure stable and uniform flow at the pump suction. This piping arrangement results in fewer failures over the life of the pump due to vibrations caused by flow induced turbulence. The manufacturer of the pump should also be consulted for additional specific requirements for the particular pump

API Standard Tubing and Casing Thread Connection The basic situation of API standard tubing and casing thread connection: The API standard threaded connection of tubing and casing in petroleum special pipes consists of two parts: pipe or male end and coupling or female end. Those with external threads are called pipes or male ends, and those with internal threads are called couplings or female ends. The two male ends are connected by a coupling, which is a short tube with an outer diameter slightly larger than that of the pipe. Both ends have internal threads. All casing and line pipes with API threads and couplings are not thickened. The tubing is not thickened or thickened on the outside. The inner diameter of the pipe end is approximately equal to the inner diameter of the pipe body, but the outer diameter of the thickened end is larger than that of the pipe body, and the two ends of the integral connecting tubing are thickened. The API specification includes 4 kinds of threads, namely, line pipe thread, round thread, buttress thread and direct connection type thread. Line pipes, round threads, and trapezoidal threads are required to be matched together during screwing and assembly to prevent leakage from the threads with sealing filler grease. The thread end of the direct connection type casing is designed to be sealed, and the sealing of the direct connection type connection is realized by a metal-to-metal seal. The main parameters of API standard threads include: (1) Thread length, (except for trapezoidal thread): the length from the starting point (pipe end) of the thread to the vanishing point; (2) Thread height: the distance between the top of the thread and the bottom of the tooth; (3) Pitch: the distance from any point of the thread to the corresponding point of the adjacent tooth in the axial direction; (4) Thread taper: the change in thread diameter per inch of thread length expressed in inches; (5) Close distance: the distance measured in the axial direction from the end face of the pipe or coupling to the tightening position of the ring gauge or plug gauge; (6) Thread tail taper (only partial ladder thread): The rapid retreat of the cutting tool causes a steep slope at the end of the thread.
