Product material - stainless steel
AISI 304 (08X18H10), AISI 316 (03X17H12M2)
Standard - DIN 2999
Stainless steel threaded rod
Sgon - fitting for threaded connection in pipelines. It is a hollow cylinder with threads at both ends. The lengths of the threaded sections are not the same: on the one hand - 5 – 6 turns, on the other - 20 – 30 turns. Overclocking is intended:
- for connecting adjacent sections of the pipeline, none of which can be rotated;
- for connecting plumbing, heating, gas devices;
- to create additional pipeline branches.
The connection using the overclocking is performed as follows. Its end with a short thread is screwed into threaded fittings (coupling, tee, tap, tap, valve) at the end of the connected section using sealing materials (sanitary linen, sealing paste). A lock nut and a coupling are screwed onto the end of the long-threaded fold, the free space is wrapped in linen and coated with sealing paste. This end is joined to the pipe to be connected, the coupling on the fold is screwed until it captures the pipe. A lock nut is screwed to the coupling, leaving a distance of 2 - 3 cm. This gap is wrapped with linen, the lock nut is pressed to the coupling, creating a strong connection. It provides simplicity and cost-effectiveness of repair and replacement of pipeline elements in comparison with cutting out a section of pipe with subsequent welding. For a pipeline operating in corrosive environments, for example, laid in the ground, or requiring compliance with strict sanitary standards (household water supply), it is necessary to use a threaded stainless steel bend. Its anticorrosive properties and strength characteristics ensure high reliability and durability of the pipeline. The stainless steel run-off will last several times longer than ordinary steel or galvanized.
ALFA-STAR company offers this common type of fittings in the range of sizes "frac12" - 4" and lengths from 110 to 200 mm according to DIN 2999 standard. The material of manufacture is AISI 304 steel (analog 08X18H10) and AISI 316 (03X17H12M2). Stainless steel AISI 316 has increased anti-corrosion and strength characteristics and can work in acidic and alkaline environments, including seawater.
