Class Symbols (Applicable till the end of 1990): These tubes are classified into 3 grades and their class symbols are given as: We need to know how we can get Hydrant, Pipes & Sprinkler? The Manufacturer, their address, telephone. Thanks.

Please tell me the material composition of 10B21 boron steel, with the tolerance and permissible limits in %age.

an Exclusive member you can find 6 different suppliers for the required tubes, from those who have joined the products to their account, under following products:

Yes. In addition they can biodegrade in soil and backyard compost, fresh and marine water as well as in anaerobic environments such as septic systems.

BS 1387 is EN BS 1387 and for ASTM A53 - see previous answers to: hfayez@nets.com.jo, quasiy@yahoo.com & terence.sundgren@eskom.co.za

For Casing and/or Tubing pipes sometimes grade is not indicated at all and indicated only a letter as "K", "D" etc. acc. to related yield and tensile strengths.

ASTM is an independent, not-for-profit standards-writing organization. They promulgate standards in many diverse technical disciplines. ASTM is the forum for a majority of standards in the USA, especially those related to plastic materials and products testing. ASTM writes standards and conducts educational training seminars (specifications, test methods and guides). ASTM does not conduct testing, listing, certifying, or enforcement of its standards.

Absolutely! The TTM 52 and TTM 54 are both built with the same components and hand assembled quality right here in beautiful downtown Mukilteo WA. USA, as are all Rane products.

The idea evolved from the fact that running a marathon in every state was not nearly the novel idea I thought it was at first. (Hundreds of people have accomplished the feat). So I took it up a notch.

Some colors are missing on the character cards. We've fixed most of them before we sold the books, but if yours is missing the colors, here's what they should be: For Mac Aber and other multi weaponed characters... If he has his Javelin drawn, can he do his basic moves? (24, 28, 10, 2, 32, 14, ...) The listing which follows will feature each of the published books, along with any changes, clarifications, and /or special questions which might help clarify a sticky rules issue.
