The main technical characteristics.
- Asbestos waterproofing washers are made by us of two types: for bolted connection and discharge hole in tubing.
The waterproofing washer is asbestos-bitumen for bolted connection.
It is made especially for bolted fasteners and connections in cast-iron tubing support. Washers are made for bolts of diameters 27, 30, 36, 42 mm.
Symbol: GSHA-d/h, where
- G - waterproofing;
- W - washer;
- A - asbobitumnaya;
- Y - sealing plug two inches;
- d - bolt dimeter;
- h - is the thickness of the metal spherical washer.
The waterproofing washer is asbestos-bitumen for the filling hole of the plug G-2(B) (GSHAU-2).
The waterproofing washer is asbestos-bitumen for the filling hole, often called by builders a "sealing washer" for a two-inch plug. In the very name of this washer, its main purpose is indicated, namely, sealing and waterproofing the area of space between the filling hole and the 2-inch plug plug.
Metal washers
- Mounting washers are designed for sealing polyethylene or savylene washers in bolted joints (fasteners) in cast-iron tubing fasteners used in the construction of vertical and inclined mine shafts, subway tunnel crossings and other underground structures.
- Mounting washers Tchaikovsky Hardware Factory produces two types of overhead washers and spherical washers.
Mounting plate washer (abbreviated name SMN):
It is worth noting that builders often use the name or designate washers as "conical washers". Overhead washers (conical) are made according to TU11168000-1001-176638952-2006 or THAT ONE 1102.11065-117.10-1160-11.1110
It is made especially for bolted fasteners and connections in cast-iron tubing support. Washers are made for bolts of diameters 27, 30, 36, 42 mm.

Plastic plugging plugs
- The polyethylene plugging plug (abbreviated name PTP) is intended for waterproofing the plugging holes of cast-iron tubing support during the construction of underground structures, vertical and inclined trunks, subway tunnels.
- The polyethylene plug consists of a "CUP" (a waterproofing element in the form of a cut-off plug without a turnkey head) and a "WEDGE" (a wedge-shaped insert). It is made of high-pressure polyethylene.
The main technical characteristics.
A polyethylene plug plug is made specifically for plugging holes of cast-iron tubing support with a size of G-2ʺ.
Installation: Pre-remove the temporary wooden plug from the hole in the cast-iron tubing support, clean the contact surface of the plug and tubing from dirt, dust and cement mortar. The thread is driven with a tap. Screw into the hole for pumping cement mortar, the first part of the polyethylene plug, "GLASS" with a special key to the flange. Next, a "WEDGE" is driven into the inner hole of the "CUP" to the upper level of the flange using a hand tool. Having achieved uniform compression and sealing of the polyethylene wall of the plug, which allows sealing the hole.
