Made of steel, are confined to special aplications. Their chief merit is that they can be assembled without welding: this explains their use in extremely high pressure services, particularly at or near atmospheric temperature where alloy steel is essential for strength and where the necessary post-weld heat treament is ijpractical. Screwed flanges are unsuitable for conditions involving temperature or bending stresses of any magnitude, particularly under cyclic conditions where leadage through the threads may occur in relatively few cycles of heating or stress:seal welding is sometimes employed to overcome this, but cannot be considered as entirely satisfactory.
