Cross the Knowledge of Piping Fabrication

Huh, this mind is stuck on the middle of no where, I can't think clearly, I must be got a headache. But, still I will continue this post for Piping & Fabrication, because there is so much article that I have to post. now we already reach to the letter "S" of General Definitions and now we will cross the knowledge of Piping Fabrication.

Saddle Flange.

saddle flange

Also known as tank flange or boiler flange. A curved flange shaped to fit a boiler, tank, or other vessel and to receive a threaded pipe. A saddle flange is usually riveted or welded to the vessel.

Sample Piping.
All piping, valves, and fittings used for the collection of samples of gas, steam, water, oil, etc.

Sargol.
A special type of joint in which a lip is provided for welding to
make the joint fluid tight, while mechanical strength is provided by bolted flanges. The Sargol joint is used with both Van Stone pipe and fittings.

Sarlun.
An improved type of Sargol joint.

Schedule Numbers.
Approximate values of the expression 1000P/S, where P is the service pressure and S is the allowable stress, both expressed in pounds per square inch.

Seal Weld.

seal weld

A fillet weld used on a pipe joint primarily to obtain fluid tightness as opposed to mechanical strength; usually used in conjunction with a threaded joint.

Seamless Pipe.

seamless pipe

A wrought tubular product made without a welded seam. It is manufactured by hot-working steel or, if necessary, by subsequently cold-finishing the hot-worked tubular product to produce the desired shape, dimensions, and properties.

Semiautomatic Arc Welding.

Semiautomatic Arc Welding

Arc welding with equipment which controls only the filler metal feed. The advance of the welding is manually controlled.

Semisteel.
A high grade of cast iron made by the addition of steel scrap to pip iron in a cupola or electric furnace. More correctly described as high-strength gray iron.

Service Fitting.
A street ell or street tee having a male thread at one end.

Shielded Metal Arc Welding (SMAW).

Shielded Metal Arc Welding (SMAW)

An arc welding process in which coalescence is produced by heating with an electric arc between a covered metal electrode and the work. Shielding is obtained from decomposition of the electrode covering. Pressure is not used, and filler metal is obtained from the electrode.
