Stainless steel welded pipe cap

Stainless steel welded pipe cap

Pipe cap, also known as head, plug, cap, pipe cap, or blind, is a pipe fitting welded to the pipe end or installed on the external thread of the pipe end to cover the pipe. Used to close pipelines, with the same effect as pipe plugs. The form of blind plates is similar, except that blind plates can be dismantled for sealing, while welded pipe caps cannot be dismantled. The design of the pipe cap includes a convex pipe cap, a conical shell, a reducing section, a flat cover, and a tightening mouth. Convex pipe caps include: hemispherical pipe caps, elliptical pipe caps, dished pipe caps, and spherical crown pipe caps. From the perspective of force, the convex pipe cap gradually becomes less effective than the hemispherical pipe cap, but from the perspective of manufacturing difficulty, it gradually becomes easier to manufacture.

Products Details
When splicing, the direction of the weld seam is only allowed to be radial and circumferential. In the future, this requirement may be cancelled for large pipe caps. The splicing distance should be required to be greater than 3 δ, And not less than 100mm (the welding heat affected zone is a high stress zone, and the chemical composition in this zone may be burned. Therefore, it is necessary to avoid the high stress zone, which is related to thickness. According to practical experience, the stress attenuation length is greater than 3 δ, And not less than 100mm). However, refrigeration equipment is difficult to meet this requirement due to its unique characteristics.

The formed head after splicing and the splicing welds should undergo 100% radiographic or ultrasonic testing, and the qualification level should follow the equipment shell. The final formed weld seam has the same level and proportion of detection as the equipment shell, which increases waste. For example, if the equipment shell is tested at 20% and passes the III test. The bulkhead splicing weld and the final weld are also qualified for Class III, with a welding joint coefficient of 0.85;

If the equipment shell is 100% tested, it is qualified for II. The bulkhead splicing weld and the final weld are also qualified for II, and the welding joint coefficient is 1,So although the blind end splicing is 100% tested, the qualification level varies depending on the equipment casing.

elbow
Stainless steel 45 ° elbow

Stainless steel elbows need to be protected according to certain process measures during use and production, to protect the rationality and quality of castings. Production and processing should be carried out according to certain process techniques to protect the quality of stainless steel elbows. The stainless steel elbow is protected by a long nozzle and enters below the liquid level of the ladle. The ladle is sealed with a cover, and the sealing between the long nozzle and the ladle cover is also necessary to protect the sealing performance of the casting. Before injecting water into the stainless steel elbow ladle, the ladle is filled with argon (nitrogen) for about 6 minutes to ensure that the oxygen content inside the ladle is less than 2%. A certain amount of oxygen input is strictly controlled to ensure good performance during use. Through such protection, the oxygen content in stainless steel elbows will remain unchanged or decrease to some extent.

DYH41X quick closing check valve

DYH41X quick closing check valve overview: The quick-closing check valve is mainly composed of body, valve seat, valve stem, spring, valve clack, guide sleeve and other parts. When the pump is turned on, the valve flap rises under the thrust of the water bottom to open the valve, and the spring is quickly closed under the action of the spring force. When the water flow is close to 0, the valve flap is completely closed. The phenomenon of no water backflow, and at the same time, because the water cannot flow back, no kinetic energy is generated, and the occurrence of water hammer is prevented.

Pneumatic regulating diaphragm valve

Fluorine lined pneumatic diaphragm regulating valve (ZMATF-10K) Pneumatic diphragm control valve (ZMATF-10K) The ZMATF (pneumatic open) pneumatic diaphragm regulating valve and ZMBTF (pneumatic close) pneumatic diaphragm regulating valve are composed of a multi spring pneumatic diaphragm actuator and a diaphragm valve. The diaphragm valve body has smooth flow, the throttling element is an elastic diaphragm, and there is no stuffing box on the valve cover. Therefore, the flow capacity of the valve is larger than that of general regulating valves and there is no leakage, which can be used as a shut-off valve within the allowable pressure difference range. The air opening and air closing functions are achieved by the forward and reverse actuators. This valve is suitable for regulating high viscosity fluids, suspended particles, fibrous media, toxic media, and corrosive media.
