  Pipe cap parameters:

  304 l stainless steel: 304 316 316 l, 321, 2520, 310, 316, such as material. Size: DN15-48 ") wall thickness: SCH5 - SCH160 standard: ASME DIN JIS BS GB/T, JB SH HG USES: water, beverages, beer, food, petrochemical, nuclear power, chemical fertilizer, shipbuilding, machinery, medical equipment, waterproof processing, pipes, etc. Packing: wooden box, carton service: provide technical advice, installation guide disc, such as stainless steel pipe cap r, avoid joining together, will be thinned and high stress.

  Splice weld direction when asked to only allow is radial and ring. After large stainless steel pipe cap may cancel this request. Stitching distance requirements, for more than 3 g, and not less than 100 mm (welding heat affected zone is high stress zone, and in the chemical composition of the area will be a loss. So to avoid the high stress area, the area and thickness. According to the practical experience, the stress attenuation length is greater than 3 g, and not less than 100 mm). But refrigeration equipment is difficult to meet the requirements, has its particularity.

  The butt welds joining together after forming the head, should be 100% rays or ultrasonic testing, the qualified level with the equipment shell. Finally forming the same welding seam detection level, scale and equipment shell, high waste.
