Both Screws SGP-VA Standard Nipple

• Material standard

  SGP-VA Hard PVC lined steel pipe for water supply (JWWA K116) Carbon steel pipe for SGP piping Black (JIS G3452) with primary antirust coating on the outer surface and hard vinyl chloride resin (JIS K6742) on the inner surface. Excellent corrosion resistance, oil resistance, and chemical resistance on the inner surface of the pipe. Since the inner surface is a smooth hard vinyl chloride resin, the frictional resistance is small and changes in flow rate and flow velocity inside the pipe can be minimized. Instead of the conventional hot-dip galvanized steel pipe, it is also used for water supply piping for general households, and it is also used for air conditioning cooling water and industrial water, and can be used in a wide range.

• Application

  Mainly for indoor water supply piping

• Screw standard

  An external thread type pipe joint that requires a taper male thread [symbol: R (PT)]. (Compliant with JIS B0203) Suitable for joining screws with the main purpose of tightness resistance when joining internally threaded pipe fittings, other pipe parts, fluid equipment, etc. It is suitable for the case where the exterior process, electroplating, welding, and bending are performed in the post-process.

• Maximum working pressure

  1MPa

• Mechanical strength

  Same as SGP steel pipe.

• Recommended temperature

  0 to 40 ° C when using pipe end anti-corrosion fittings

• About inspection of screw

  All thread inspections are performed using a taper thread gauge specified in the standard number (JIS B0253) defined by the Japanese Industrial Standards (JIS standard). In addition, our inspection gauge manufacturer uses OSG (OSG).

• Join method

  When tightening, after tightening by hand, it is necessary to tighten with torque using a tool such as a pipe wrench. However, in order to tightly bond, even if it is tightened tightly, there is a slight space between the top and bottom of the mountain in practical use, and perfect airtightness cannot be secured. Therefore, it is necessary to take measures such as wrapping seal tape (tape-like gap filling material) around the screw before assembly or applying the same liquid sealant. (It is necessary to select the type of sealing material suitable for the piping application.) Also, when assembling in a place where attention is paid to leakage, seal tape (about 2 to 3 turns) is wound around the external thread. Apply sealant from the top, and then apply sealant on the female screw side and tighten it to ensure tightness.

• Inspection pressure

  Leakage(pneumatic)	0.5Mpa(5.1kgf/cm2)
  Pressure resistance(water pressure)	2.5Mpa(25.5kgf/cm2)

• Type, symbol, chemical composition

  Type	Symbol	Chemical composition(%)
  		P	S
  Carbon steel pipe for piping	SGP	0.040 or less	0.040 or less
