GENERAL PROPERTIES:-

317L is a molybdenum bearing, low carbon content "L" grade austenitic stainless steel that provides improved corrosion resistance over 304L and 316L stainless steels. The low carbon provides resistance to sensitization during welding and other thermal processes. 317L is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding.

APPLICATIONS:-

  • Flue-gas desulfurization systems
  • Chemical process vessels
  • Petrochemical
  • Pulp and Paper
  • Condensers in power generation

CORROSION PROPERTIES:-

317L has excellent corrosion resistance in a wide range of chemicals, especially in acidic chloride environments such as those encountered in pulp and paper mills. Increased levels of chromium, nickel and molybdenum compared to 316L stainless steel improve resistance to chloride pitting and general corrosion. Resistance increases with molybdenum alloy content. 317L is resistant to sulfuric acid concentrations up to 5 percent at temperatures as high as 120°F (49°C). At temperatures under 100°F (38°C) this alloy has excellent resistance to solutions of higher concentration. However, service tests are recommended to account for the affects of specific operating conditions that may affect corrosion behavior. In processes where condensation of sulfur-bearing gases occurs, 317L is much more resistant to attack at the point of condensation than conventional alloy 316. The acid concentration has a marked influence on the rate of attack in such environments and should be carefully determined by service tests.


WELDING:-

317L is readily welded by a full range of conventional welding procedures (except oxyacetylene). AWS E317L/ER317L filler metal or austenitic, low carbon filler metals with molybdenum content higher than that of 317L, or a nickel-base filler metal with sufficient chromium and molybdenum content to exceed the corrosion resistance of 317L should be used to weld 317L steel.


CHARACTERISTICS:-

  • Improved general and localized corrosion to 316L stainless
  • Good formability
  • Good weldability

Fittings and Flanges for Stainless Steel Pipe
Stainless steel piping systems can be joined by butt welding and, in the heavier 40S and 80S schedules, with threaded connections.

BUTT WELDING STAINLESS STEEL PIPE FITTINGS

Harsh steel stocks butt welding fittings in the following configuration.

  • Elbows 45 degree and 90 degree - long radius and short radius.
  • Return bends 180 - long radius and short radius.
  • educers - concentric and eccentric.
  • Tees - equal and reducing.
  • Caps.
  • Stub ends - Type B.

Advantages of stainless steel butt Weld fitting to the pipe are to keep pipes permanently leak proof. The continuous structure helps strength between pipes and fittings. It reduces pressure and also minimises the action of corrosion and erosion. Butt welding fittings can be supplied in either seamless or welded construction and are covered by specifications ASTM A403M and ASTM A815M for Duplex grades.

STAINLESS STEEL SCREWED AND SOCKET WELD FITTINGs

Stainless steel piping systems can be connected using stainless steel screwed fittings - BSP threaded ("150lb") low pressure stainless steel fittings and NPT class 3000 high pressure stainless fittings in Grade 316. Socket weld fittings are used in high pressure piping systems and available in grade 316L to suit schedule 80S wall thickness piping.


MANUFACTURING SPECIFICATIONS:

  • ASTM A182M (3000lb NPT and socket weld).
  • ANSI B16.3 (BSP dimensions)
  • ISO 4144 (BSP dimensions)

STAINLESS STEELS FITTINGS AND FLANGES:

A flange is a ring of steel (forged, cut from plate, or rolled) designed to connect sections of pipe, or to join pipe to a pressure vessel, valve, pump or other integral flanged assembly. Flanges are joined to each other by bolts, and to the piping system by welding or threading (or loose when stub ends are used). Forged stainless steel flanges are designed to the following common pressure ratings, stainless steel flanges are exported by Harsh Steel in Classes 150, 300, 600, 900, 1500 and 2500. Standard sealing face is Raised Face (RF).
The basic types of flanges are:

  • Stainless steel slip-on flange
  • Stainless steel socket weld flange
  • Stainless steel blind flange
  • Stainless steel lap joint flange
  • Stainless steel weld neck flange
  • Stainless steel threaded flange
  • Stainless steel orifice Flange

Manufacturing specification: ASTM A182M
Plate stainless steel flanges are cut and machined from plate - Table 'D', Table 'E', etc.
Manufacturing specification: AS2129.
Types and applications of Stainless steel and Nickel alloy flanges

Slip-on flanges The flange is slipped over the pipe and then welded both inside and outside to provide sufficient strength and prevent leakage. Slip-on flanges are also used as loose back-up flanges when stub ends are used.
Blind flanges This is a flange without a centre bore, used to shut off a piping system or vessel opening
Weld neck flanges This is a flange without a centre bore, used to shut off a piping system or vessel opening
Lap joint flanges This is again similar to a slip-on flange, but has a radius at the intersection of the centre bore and the flange face to accommodate a lap stub end.
