Technical requirements for straight seam elbows
Straight seam elbow technology requirements are strict, high quality requirements, easy installation, long service life and other characteristics. So need to go through before construction welding welding technology training for installation, welding certificate, obtain corresponding project may show certificates, pipelayer also after large diameter stainless steel pipe installation process training, understand the characteristics of the straight seam pipe bend pipe production and processing technology, can skilled operation procedures and specifications before mount guard after installation.
Before installation and construction of straight seam elbow pipe fittings, first confirm the size and measurement of pipe supply and meet the requirements of installation. All straight seam elbow main materials should be packaged during transportation. All main materials should be packaged in good condition and accompanied by the corresponding material quality certificate. It needs to be properly preserved and protected to prevent pollution. The straight seam elbow pipe has beautiful appearance and quality assurance. It meets the corresponding standard requirements in the production process, without scratches, cracks, beautiful appearance and accurate bending Angle. All customers who order straight seam elbow pipe fittings from our company, our company shall mark and record the materials that do not meet the requirements, and store them separately.
Straight seam elbow pipe fittings are divided into; Long radius elbow and short radius elbow, short radius elbow refers to bend radius to 1 times the diameter of the pipe to practice car, also known as 1 d, the bend radius of curvature is equal to 1 times the diameter of the tube, is usually a 90 - degree Angle, looked from the intuitive, short radius elbows are much shorter than the long radius elbow, elbow bending radius according to the customer's requirements and use of the production processing. Long radius elbow is a common elbow pipe fitting product. The general default is long radius elbow, high pressure or high flow rate of the place with long radius, if it is a solid pipeline resistance requirements are strict when the use of large radius elbow, short radius is generally used in low pressure fluid or elbow is limited. All customers who order straight seam elbow pipe fittings of our company, before ordering, the customer shall first explain whether long radius elbow or short radius elbow, generally speaking, the default long radius elbow quotation is not said.
