WATER PIPELINE JOINING METHODS AND PIPE INSTALLATION

JOINING METHODS AND PIPE INSTALLATION This data sheet describes the most common joining methods of steel water mains and the most important phases of installation. Applications • water mains • sewage pipes   1. Trench, foundation and filling The trench is dug wide enough, according to Figure 1, so as to have enough working space on both sides of the pipeline. If necessary, a levelling course is laid on the bottom of the trench. It is to be at least 150 mm thick measured from the exterior bottom of the pipe (See Fig. 2). The max. allowed grain size of the […]

Difference Between SCH 40 and SCH 80 Steel pipe

“Schedule 40” and “Schedule 80” refer to the thickness of the walls of pipes. “Schedule” is the standard of wall thickness that has been adopted by the American National Standards Institute. As per the Institute, the thickness of wall pipes varies from Schedule 10, Schedule 40, Schedule 80, and Schedule 160. Pipes with Schedule 40 come with standard weight, and pipes with schedule 80 come with extra strength. The materials used for making Schedule 40 and Schedule 80 come from the same material. Schedule 80 pipes have a thicker wall than Schedule 40 pipes. As such, Schedule 80 pipes are […]

The difference between ERW steel pipe and spiral steel pipe

Steel pipes can be seen everywhere in our daily life. It is widely used in heating, water supply, oil and gas and other industrial liquids, which brings great convenience to our life and production. According to the tube forming technology, steel tubes can be roughly divided into the following four categories: seamless steel tubes, high-frequency welded tubes, LSAW tubes, and spiral submerged arc welded tubes. According to the form of the weld we can be divided into seamless steel pipe, ERW steel pipe and spiral steel pipe. We have made a corresponding comparison of ERW steel pipes and spiral steel […]

Large diameter welded pipe main production process description:

1. Prospecting: After the steel plate used for manufacturing large-diameter submerged arc welded straight seam steel pipes enters the production line, a full-plate ultrasonic inspection is first performed; 2. Milling: Double-sided milling of the two edges of the steel plate by the edge milling machine to achieve the required plate width, plate edge parallelism and groove shape; 3. Pre-crimping: Pre-bending machine is used to pre-bend the edge so that the edge of the board has a curvature that meets the requirements; 4. Forming: In the JCO molding machine, first half of the pre-bent steel plate is punched several times and […]
