Adjustable pipe clamp

A method of welding together ends of first and second pipes comprising the steps of:

• a. securing a first clamp corner to a second clamp corner to create a first clamp half;
• b. securing a third clamp corner to a fourth clamp corner to create a second clamp half;
• c. placing a first end of said first pipe adjacent a first end of said second pipe to create a site for welding said first and second pipes together;
• d. placing said first clamp half adjacent a first side of said site and said second clamp half adjacent a second side of said site;
• e. securing said first clamp half to said second clamp half to create an adjustable clamp having a first and second weld windows;
• f. welding together said first and second pipes within said first and second weld windows;
• g. wherein each said clamp corner comprises:
• g1. a first transverse aperture;
• g2. a second transverse aperture;
• g3. a third parallel aperture;
• g4. wherein the first and second transverse apertures are transverse relative to a first axis perpendicular to the pipes and the third parallel aperture is parallel relative to the first axis;
• and
• h. wherein said step of securing said first clamp corner to said second clamp corner comprises:
• h1. placing a first transverse bolt within the first transverse aperture of said first clamp corner and a second transverse bolt within the second transverse aperture of said first clamp corner;
• h2. placing a first spacer around the first transverse bolt and a second spacer around the second transverse bolt;
• h3. placing said first transverse bolt within the first transverse aperture of said second clamp corner and said second transverse bolt within the second transverse aperture of said second clamp;
• and
• h4. securing a first transverse lock nut to an end of said first transverse bolt and a second transverse lock nut to an end of said second transverse bolt.
