16mn Sanitary Pipe End Cap For Waterproof Treatment

Description

Mechanical Purpose: Pipe fittings that are welded at the end of the pipe or installed on the thread outside the end of the pipe to cover and plug the pipe. It is used to close the pipeline and has the same function as pipe plugging. The form of blind plate is similar, but the blind plate can be disassembled and blocked, while the welded pipe cap can not be disassembled.

The cap includes the design of convex cap, conical shell, variable diameter section, flat cover and contraction opening. The convex cap includes: hemispherical cap, elliptical cap, dish cap and spherical cap. Materials can also be divided into 20G, 20, Q235, Q345, Q345D, 16Mn, 12Cr1MoVG, 15CrMo, 304, 304L, 316L, 321, 2520, 310, 317 and other materials. Path: DN15-DN2020; Wall thickness: SCH5-SCH160-XXS

Standard: ASME DIN JIS BS GB/T JB SH HG,

Specifically as follows: GB/T 12459-2005, GB/T 13401-2005, ASME B16.9, SH3408, SH3409, HG/T 21635, DL/T695, SY/T 0510, DIN 2617

Uses: water, beverage, beer, food, petrochemical industry, nuclear power, machinery, medical equipment, chemical fertilizer, shipbuilding, waterproof treatment, pipeline, etc.

The R part of the disc cap avoids splicing, which will reduce the thickness and increase the stress.

When splicing, only radial and circumferential weld directions are allowed. This requirement may be cancelled in the future for large pipe caps. The splicing distance shall be more than 3 δ and not less than 100 mm (the heat affected zone of welding is a high stress zone, and the chemical composition in the zone will be burnt. So avoid the high stress area, which is related to thickness. According to practical experience, the stress attenuation length is greater than 3 Delta and not less than 100 mm. But refrigeration equipment is difficult to meet this requirement, and has its particularity. After splicing, 100% X-ray or ultrasonic inspection should be carried out on the splicing weld of the formed head, and the qualified level should follow the equipment shell. The final weld inspection level and proportion are the same as the equipment shell. If the equipment shell is 20% inspected, III is qualified. The stitching weld and final weld of the stuffy head are also qualified for III, and the coefficient of weld joint is 0.85.
