Product Information

inch (390mm) barrel diameter and firing a 220lb (100kg) hollow ball filled with gunpowder and used during the English Civil War in 1646. Fin-stabilised mortar bombs do not have to withstand the rotational forces placed upon them by rifling or greater pressures, and can therefore carry a higher payload in a thinner skin than rifled artillery ammunition. The archetypes are the Brandt Mle CM60A1 and Brandt 60 mm LR, which combine features of modern infantry mortars together with those of modern cannon. As time passes, you will note that the cement seal at the base of your flue pipe, where it blends into the outlet collar of the stove flue, has broken or crumbled, probably because of the slight shift in the stove balance when you open and close the door over many months. Choi Hae-san (최해산, 崔海山) (1380–1443), the son of Choe Mu-seon (최무선, 崔茂宣) (1325–1395), is generally credited with inventing the wan'gu.

Wherever you have a mixture of new black and old grey fire cement in the joint, it is recommended to leave the masking tape in place and use heat-resistant spray paint to dry it. It is supplied in various dimensions and colours, such as grey/buff and black fire cement, depending upon your preference and requirements. Based on Orbital ATK's Precision Guidance Kit for 155mm artillery projectiles, XM395 combines GPS guidance and directional control surfaces into a package that replaces standard fuses, transforming existing 120mm mortar bodies into precision-guided munitions. He then cleans the joints with a narrow, stiff-bristle scrub brush and sweeps up the mortar crumbs with a wet/dry vac. An Italian account of the 1456 siege of Belgrade by Giovanni da Tagliacozzo states that the Ottoman Turks used seven mortars that fired "stone shots one Italian mile high".

He is just as adept in providing his unit with water as he is with handling explosives, building a bridge or fortifying defensive positions. Especially since it does not come in contact with the stove, but only gets heat from the pipe, any amount of heat from medium to high setting should do the job in around four to six hours. Typical areas of use include health and leisure facilities, schools, universities, hotels, commercial, retail and industrial buildings.

Mortars are made in different sizes, from large and heavy mortars to infantry mortars which can be carried by just one soldier. After World War II the Belgium Fly-K silent spigot mortar was accepted into French service as the TN-8111. A sinking projectile detonated if it struck a submarine, and the pattern was such that any submarine partly in the landing zone of the projectiles would be struck one or more times. The XM395 munition consists of a GPS-guided kit fitted to standard 120mm smoothbore mortar rounds that includes the fitting of a nose and tail subsystem containing the maneuvering parts.Our fire cements, heat proof plasters and other aggregates offer excellent heat resistant properties.
